Php
Could the statement "PHP must be compiled with LDAP support for any functionality at all" be explained further? I'm not a developer and simply downloaded php5 from php.net and followed config instructions to get mediawiki running. I never compiled php. According to php.net I would need some development tools to compile php? What is needed to change the default version of php5.1.2 windows package to be 'compiled' for LDAP? Can I just configure some extension from php.ini? my specific situation is Windows2003/IIS/php/mysql.
 * There is quite a bit of documentation on how to get LDAP working with PHP, and specifically with windows. I believe someone even posted some info on the content page of this article. I believe this is probably beyond the scope of this documentation. --Ryan Lane

Problem with autocreated users
Dangerous code snipped


 * You need to figure out what your real problem is. If there is some incompatibility between 1.10 and the plugin, I'll be happy to track down the problem and fix it (either in the core code, or the plugin). --Ryan lane 19:49, 6 August 2007 (UTC)


 * Exactly same issue as above! $wgLDAPUpdateLDAP, $wgLDAPMailPassword and $wgEmailAuthentication == false.
 * -- 22:11, 15 August 2007 (UTC)


 * ... I need more information than "it isn't working." Please post your configuration, and your debug info, with sensitive stuff snipped out. I've heard multiple reports of this working fine with 1.10. --Ryan lane 01:05, 16 August 2007 (UTC)


 * Oh, btw, all three of those are false by default, and use domain (array) style configuration. I'm betting it is pretty likely your configuration is messed up. --Ryan lane 01:07, 16 August 2007 (UTC)


 * I too was having difficulties with LDAPAuthentication for new AD users. You can view the history of this article for all my configuration settings and debugging output, but the crux of it was a "external authentication database error or you are not allowed to update your external account" error when trying to use LDAPAuthentication 1.0h on new Active Directory users and a "Login incorrect" error for all users when trying to upgrade to LDAPAuthentication 1.1g.


 * In the end I suspect it was because LDAPAuthentication 1.0h used plain LDAP binding to authenticate by default whereas the newer 1.1g uses TLS by default. By setting $wgLDAPDebug = 3 I was able to see both TLS and SSL options failing suggesting that I first need to learn about these protocols and why my server doesn't seem to support them. Setting $wgLDAPEncryptionType = array("DOMAIN"=>"clear") in conjunction with using LDAPAuthentication 1.1g allowed login via straight LDAP binding, but it would be good to get some info about the security issues of using clear binding on a semi-private wiki (internal server, accessible to outside world, logins required).

Verified to work with 1.10
I've tested this pretty throughly, and I have yet to have issues with MediaWiki 1.10; if anyone has problems that can be linked to 1.10, let me know. --Ryan lane 13:25, 20 August 2007 (UTC)

LdapAuthentication.php up to 1.1c (>=1.1d can skip this)
I've added a bug into MediaWiki's bugzilla to get part of this fixed. One part of the workaround is in my code (which will be fixed and released soon), and the other is in MediaWiki's code. So, to make it work, please change the following in LdapAuthentication.php in the initUser function (if using 1.1c or below):

$user->setPassword( '' );

to:

$user->mPassword = '' ;

and add the following function to LdapAuthentication.php:

/**        * Can the wiki change passwords in LDAP? * Return true if yes. *        * @return bool * @access public */           function allowPasswordChange { global $wgLDAPUpdateLDAP, $wgLDAPMailPassword;

if ( isset($wgLDAPUpdateLDAP[$_SESSION['wsDomain']]) ) { $updateLDAP = $wgLDAPUpdateLDAP[$_SESSION['wsDomain']]; }               if ( isset($wgLDAPMailPassword[$_SESSION['wsDomain']]) ) { $mailPassword = $wgLDAPMailPassword[$_SESSION['wsDomain']]; }               if ( $updateLDAP || $mailPassword ) { return true; } else { return false; }              }

SpecialUserlogin.php (all Versions MediaWiki 1.9.x)
And in includes/SpecialUserlogin.php you can use the following patch (you probably want to patch by hand since this patch is against SVN):

--- SpecialUserlogin.php       (revision 19677) +++ SpecialUserlogin.php       (working copy) @@ -307,13 +307,18 @@        * @private */       function initUser( $u ) { +              global $wgAuth; +               $u->addToDatabase; -              $u->setPassword( $this->mPassword ); + +              if ( $wgAuth->allowPasswordChange ) { +                      $u->setPassword( $this->mPassword ); +              } +                $u->setEmail( $this->mEmail ); $u->setRealName( $this->mRealName ); $u->setToken; -              global $wgAuth; $wgAuth->initUser( $u ); $u->setOption( 'rememberpassword', $this->mRemember ? 1 : 0 );

Please let me know if this fixes the problem
I don't currently have the ability to test MediaWiki 1.9 w/ LDAP authentication, please let me know if this fixes your problem. --Ryan Lane 18:16, 13 February 2007 (UTC)

With a config very similar to Robert, above, and applying you fixes everything seems to be working fine for me. -- sterling 144.92.220.30 20:30, 15 February 2007 (UTC)

The above config changes together with LDAPAuthentication 1.1d fixing the problem with MediaWiki 1.9.2 and LDAP authentication against Novell eDirectory. Thanx a lot! -- Günther Rasch 07:35, 22 February 2007 (UTC)

Shit yeah! I've been trying to make this work for 2 days straight and I missed this last step. Works like a charm. :) -- Jonathan Puddle

This is exactly what i was searching for. Now every LDAP-user ist automaticaly registered while logging in at the first time, and authenticates with LDAP-password. Thanx a lot! -- Jens Vieler, 21 March 2007

This worked for me. Against both AD and Linux LDAP. Thanks much! -- John Harris, 23 March 2007 (Virginia Tech, ECE)

This fix stopped me to sweat over the ldap issue I have been having. Thanks!!!! - Mutuk March 27 2007.

PHP errors in allowPasswordChange
This fix produces PHP errors because your local variables $updateLDAP and $mailPassword are not properly scoped. (Enable onscreen PHP errors to see them.) You have defined these variables inside the IF statements, but your final test is outside. So these error messages are produced for the if ( $updateLDAP || $mailPassword ) test:

Notice: Undefined variable: updateLDAP in ....\extensions\LdapAuthentication.php on line 596

Notice: Undefined variable: mailPassword in ....\extensions\LdapAuthentication.php on line 596

To fix, just set both variables to the empty string just below the "global" line. Maiden taiwan 02:29, 1 March 2007 (UTC)


 * Well, they aren't errors, just warnings. Another user has pointed this out (I'm too lazy to find it now), and it'll be fixed in the next release. Ryan Lane 14:30, 1 March 2007 (UTC)

allowPasswordChange doesn't check for $wgLDAPUseLocal
This fix causes another bug. If $wgLDAPUseLocal is set to true and no LDAP user with write permission is specified, then when someone tries to create a new account and the wiki attempts to add the user's password to the database, it first checks with $wgAuth->allowPasswordChange which returns false. This causes the user to be added to the database fine but with no password. The user is logged in, but once they log out their account has no password so they can never get back in. --Christian 15:57, 17 April 2007 (UTC)

if ( 'local' == $_SESSION['wsDomain'] ) { return true; }


 * You can fix this by adding the above to the beginning of the function allowPasswordChange --Christian 16:13, 17 April 2007 (UTC)


 * Thanks for the report and fix; this will be in the next release. Ryan lane 02:45, 18 April 2007 (UTC)


 * This is fixed in svn right now if it is causing you any issues. Ryan lane 02:45, 18 April 2007 (UTC)


 * After overwriting 1.1d with 1.1e on 1.9.3, my password is no longer accepted. I'm using AD 2003.  Are there any additional tweaks that need to be done?  163.252.39.78 14:56, 18 April 2007 (UTC)


 * 1.1d to 1.1e was essentially just bug fixes. It shouldn't have broken anything. I'll need debugging info from you, and your configuration with anything sensitive snipped out. --Ryan lane 15:04, 18 April 2007 (UTC)


 * I just tried to apply this fix to the top of allowPasswordChange but it had no effect. I had to simply put "return true;" at the top of the function for my logins to work.  This was with $wgLDAPUseLocal set to 'true'.  (Setting it to 'false' caused the same password-change-forbidden error before I applied my hack, though).  This is on mw 1.9.3 and plugin 1.1e.  --138.26.64.50 15:35, 24 April 2007 (UTC)


 * I just checked this using the SVN version. It seems to be working for me. I'm working on the plugin right now, so don't use HEAD, try revision 24891 (or you can wait for the release of 1.1f) --Ryan lane 01:39, 18 August 2007 (UTC)


 * I installed this and am getting the same error message "password-change-forbidden". I get the same error regardless of what $wgLDAPUseLocal is set equal to.  Is it trying to set the password in Active Directory, or in the MySQL Database?  I am using the 1.1g version.  Thanks, Shane.


 * Are you using MediaWiki 1.9? If so, upgrade MediaWiki, or follow the instructions posted on how to fix the problem. I won't actively support issues with versions of MediaWiki that are out of support (with the exception of 1.6, until PHP5 is readily available most places). --Ryan lane 14:11, 5 November 2007 (UTC)


 * Thank you, I was using 1.9, I upgraded to 1.11 and it logged in without any issues.

Nested Groups option not working
Hello All,

I know this isn't a default plugin for MediaWiki, but I am sure that others are using LDAP authentication.

I am using the Ldap plugin on the mediawiki site and I am unable to get nested groups working. I can authenticate when a user is part of a specific group, but when a group is added to the required group it does not work.

Below is my nested groups array in my Localsettings.php file.

$wgLDAPGroupSearchNestedGroups = array( "domain.com"=>true );

I am running mediawiki 1.9.3, php 5.2.0, apache 2.2.3 and Version 1.1c 12/04/2006 of this module.

Can anyone help me out with this?

What can I do to fix this or get further assistance?

Thanks :)

 * This looks like it may be a bug. The part about "Returned groups" looks completely wrong. It shows the same group a bunch of times. All the looping is pretty strange too. Can you post your configuration with sensitive stuff snipped out? --Ryan lane 13:30, 27 March 2007 (UTC)

Was this issue ever resolved? I am having the same problem. The only difference is I am doing a straight bind. Any ideas? Thanks.


 * I just noticed that "$wgLDAPGroupNameAttribute" isn't defined here... it should be defined as $wgLDAPGroupNameAttribute = array ("domain.com"=>"cn"); --Ryan lane 22:48, 30 June 2007 (UTC)

I still can't get it to work. Same errors. Just to clarify, should that be $wgLDAPGroupNameAttribute = array ("domain.com"=>"cn"); or should I substitute cn for my master group name that contains the nested groups that need to be searched? I tried it both ways, but I wanted to make sure my syntax was right. MIS is the master group that contains a bunch of other nested groups. So here is what I used with all the sensitive information removed.

require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array( "domain.com" ); $wgLDAPServerNames = array( "domain.com"=>"server1.domain.com server2.domain.com" ); $wgLDAPSearchStrings = array( "domain.com"=>"USER-NAME@domain.com" ); $wgLDAPEncryptionType = array( "domain.com"=>"clear" ); $wgLDAPUseLocal = true; $wgMinimalPasswordLength = 1;

$wgGroupPermissions['*']['edit'] = false;
 * 1) Disable anonymous editing

$wgGroupPermissions['*']['createpage'] = false;
 * 1) Anonymous users can't create pages

$wgGroupPermissions['*']['read'] = false;
 * 1) Disable reading by anonymous users

$wgStrictFileExtensions = false; $wgCheckFileExtensions = false; $wgMimeDetectorCommand= "file -bi"; require_once("extensions/SpecialPdf.php");

$wgLDAPRequiredGroups = array( "domain.com"=>array("cn=mis,ou=groups,ou=site1,ou=sites,dc=domain,dc=com") ); $wgLDAPGroupUseFullDN = array( "domain.com"=>true ); $wgLDAPGroupObjectclass = array( "domain.com"=>"group" ); $wgLDAPGroupAttribute = array( "domain.com"=>"member" ); $wgLDAPGroupSearchNestedGroups = array( "domain.com"=>true ); $wgLDAPBaseDNs = array( "domain.com"=>"ou=administrators,dc=domain,dc=com" ); $wgLDAPSearchAttributes = array( "domain.com"=>"sAMAccountName" ); $wgLDAPGroupNameAttribute = array( "domain.com"=>"mis" );
 * 1) DNs in $wgLDAPRequiredGroups must be lowercase, as search result attribute values are...
 * 2) $wgLDAPRequiredGroups = array( "domain.com"=>array("cn=mis-tech-2,ou=groups,ou=administrators,dc=domain,dc=com", "cn=mis-tech-1,ou=groups,ou=administrators,dc=domain,dc=com") );
 * 1) $wgLDAPGroupSearchNestedGroups = array( "domain.com"=>false );
 * 1) $wgLDAPBaseDNs = array( "domain.com"=>"ou=groups,ou=administrators,dc=domain,dc=com" );

$wgLDAPDebug = 3;

It should be this exactly (copy, paste): $wgLDAPGroupNameAttribute = array( "domain.com"=>"cn" );

Once you make this change and authenticate, you should notice this line Returned groups:,,,,,,,,,,, Change to Returned groups:mis-tech-2,mis-tech-1,etc Basically, it will return the actual groups instead of ,,,,,,,,,. Once it returns the groups, does the Nested Groups work? It's still not working for me. I'm going to make a post to the mailing list. 2007-07-02

I made the change and it did return the proper groups instead of just the commas, but the login still isn't working.

In my case, I can log in if the user is in one of the $wgLDAPRequiredGroups, however, I CANNOT log in when my user is in a group, that is in one of the $wgLDAPRequiredGroups (ie, Nested). In the case of a nested group, I get what you are getting, my debug log shows massive looping when "Entering searchNestedGroups" and "Entering getUserGroups". I'm assuming this has something to do with our GroupNameAttribute, but my PHP is limited. Here is my post to the mailing list. I haven't received a reply yet: http://lists.wikimedia.org/pipermail/mediawiki-l/2007-July/021463.html


 * Ignore the last thing I wrote (now erased). I'm reading my own function very poorly :) (stupid recursion). $wgLDAPGroupNameAttribute should definately be set as "cn", as that seems to be the naming attribute of your group. The massive looping may be a bug, as I've noticed it happening to a few people. It also may just be poor debug logging on my part. I'm going to change around the logging some to be less spammy, and more informative. Hopefully it'll help us track this problem down. --Ryan lane 19:55, 6 July 2007 (UTC)

Ryan, If you need help recreating the error, or testing, I'm available M-F 9-6 PST. You can get my email from the post http://lists.wikimedia.org/pipermail/mediawiki-l/2007-July/021463.html

Same here. I can help test too. This is a big issue for me in getting this implemented. GT4NE1 at gmail dot com Thanks

Nested groups works fine for me, but...

I use LDAP auth extension to authenticate against AD with quite complicated structure with global groups consisting local groups. Users are members of "departmental" groups, that belong to local level, only. So effectively there is 3 level structure, with users in bottom level groups. When I specify "top level" groups as required ($wgLDAPRequiredGroups) then authentication process takes up to 1min, sometimes even longer. (BTW it is possible to have more then one group in $wgLDAPRequiredGroups array).

So my point is - would it be possible to have some caching for LDAP queries, as vast number of queries performed in authentication process are for groups resolving.

Thanks, Pawel

Fixed in SVN (1.1f)
I believe I've fixed the problem. I had some caching issues on searches, that speed up group searching/syncing, but completely clobbered nested group searching. I modified the caching stuff to take into account nested group searching; everything should be working now. Please test this out, and let me know. --Ryan lane 13:21, 20 August 2007 (UTC)
 * Tested in a 3-level nested group, works perfectly. Thanks a lot! --Guillaume Moutier 19:32, 30 August 2007 (UTC)
 * Confirmed working in 1.1g (alpha). Great work Ryan!  Thanks!

initUser bug is fixed in current mediawiki svn
I setup MediaWiki 1.9.3 and LdapAuthentication.php but got errors about "password-change-forbidden" when logging in as a user in LDAP but not yet in the MW DB. I found that this bug is already fixed in mediawiki svn, just not yet in a released version. If you encounter this, apply this small change:

http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/includes/SpecialUserlogin.php?r1=20158&r2=20300

Multiple domains leads to username clash?
We're running a multi-domain AD environment, and I'm hoping this LDAP extension will make mediawiki "intergratable" into our environment.

So I've set up the ability for our users to login from the different domains, including myself as "dom1/user1". However, now I've logged in, I notice my mediawiki "account" is actually "user1" - ie the "dom1" has disappeared.

Well, we definitely have many instances of username "clashes" - eg there's a "dom3/user1". Won't that mean "dom3/user1" logging in will end up in my mediawiki profile?

Owch :-(

Update: I just had a thought. As slashes of all description are bad as username chars, perhaps getting the AD-retrieved email address to become the mediawiki account name would be the best workaround? e.g. dom1/user1 logs in, and finds themselves in a mediawiki account profile named "user@email.address" instead of the non-unique "user1"?


 * Email addresses likely won't work as the @ symbol is illegal in user names. Maybe I'll try to work some domain conflict resolution stuff into the next version. --Ryan lane 14:22, 28 October 2008 (UTC)


 * How about just DOM "-" USERNAME (eg dom-jhaar). Your "conflict resolution" comment implies you think it should remain "username" unless a clash occurs? I think that would be unwise - specifically as it leads to inconsistancy. What about defaulting to "dom-username", and having (new variable) "$wgLDAPIgnoreDomainInAccountName=1" as the default. That would then allow a new release to by default act like old releases, but would enable users like me to set to zero and enable the multi-domain account support? --Jason Haar 10:30, 30 October 2008 (NZDT)


 * When I said conflict resolution, I meant adding something like user@domain or DOMAIN\user. I can't promise anything soon. I'm not really a big fan of dom-user; something more common would be nice. I'll take patches to fix this, but it would probably be a good idea to run the ideas through me before coding them up. --Ryan lane 22:38, 3 November 2008 (UTC)
 * I've already looked at user@domain - but the interwiki code appears to misinterpret that? It sort of works - but if you try to change wiki group membership using such accounts, it fails. The backslash would be most "Windows-like" - but as an escape char, it might be misinterpreted by all sorts of things? The forward slash is likewise not a usable choice - which is why I was suggesting lame things like hyphens --Jason Haar 19:44, 6 November 2008 (NZDT)

Problems with underlines in username (AD)
Hi I've got the Problem that users with underlines in their usernames can't login. Read in another article that I have to change $this->mTextform = str_replace( '_', ' ', $dbkey ); to $this->mTextform = str_replace( '_', '_', $dbkey ); int the Title.php. But this didn't make any difference. The Login still doesn't work with users withe underlines in their loginnames. Is there anybody who can help me? ..Thanks...


 * I honestly don't know how to fix this. The username is passed to the plugin after it is munged by MediaWiki. I'm sure there is somewhere I can hack the core code to fix this, but I haven't looked around for it yet. --Ryan lane 22:50, 30 June 2007 (UTC)

I had the same problem and fixed it with a small edit in the plugin. I added a line at the beginning of the function "getSearchString" $username = str_replace(' ','_',$username); This replaces the space with an underscore when it creates the user username that is sent to the LDAP server. As far as MediaWiki is concerned it will still use the space in the name. --JoeD July 7th 2007

Internal server error on login
Ok, so i've setup the wiki before the weekend, and it was working all just fine with LDAP-authentication. Now on monday, when logging in with a user that already exists in the database it comes up with the following Internal server error: Database error A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "User::addToDatabase". MySQL returned error "1062: Duplicate entry 'ldap-username' for key 2 (localhost)". Where ldap-username is ofcourse the ldap-user. When I delete the ldap-user from the database, logging in works just fine, but after logging out and in again it comes up with the same error message. It's strange because nothing has changed on the server over the weekend as logging on and off was just working fine last week. With debugging on the authentication has passed. Somehow it is trying to add the user again, while instead it has to update it if I am correct? Anybody got any ideas? -Martin
 * BTW, I am using the following setup: MediaWiki: 1.9.3, PHP: 5.2.1, MySQL: 5.0.37, LDAP plugin 1.1d. -Martin
 * Ok, so I fixed the problem, by making a dump and dropping the database. After this importing the database fixed the problem. Somehow there is some caching issue here, but I cannot seem to know which. Also I didn't use database caching upon installation. Maybe this helps somebody out or maybe Ryan can take a look at it in furter development. -Martin


 * Did you mess around with your database manually? I don't remember any entry called ldap-username... The plugin doesn't ever touch the database directly. --Ryan lane 21:34, 1 May 2007 (UTC)

Making work with Pywikipediabot
Has anyone had any experience getting pywikipediabot to work with LDAP? I tried it and it seems to not work because it can't successfully select the domain name. Any thoughts?

HotMonkeyAC 18:25, 27 April 2007 (UTC)


 * See: Extension talk:LDAP Authentication. This is a similar issue. the domain stuff is a valid part of the software, and bot frameworks should be providing that info on login. The pywikipediabot developer needs to fix that. --Ryan lane 20:10, 27 April 2007 (UTC)


 * one possible fix is to add the line
 * "wpDomain": self.domain,


 * to the predata array under def getCookie in login.py


 * you'll have to set self.domain somewhere else. mine is hardcoded in login.py as
 * self.domain = 'mydomain'
 * but this is very nasty. it should be set somewhere else like mywiki_family.py
 * let me know if this works for you
 * Jono Brooker 13:27, 20 June 2007 (UTC)


 * Jono, that worked perfectly.  Thank you!!!   -HotMonkeyAC 14:48, 26 June 2007 (UTC)


 * I logged a pywikipedia ticket about this. -maiden_taiwan, 09 May 2008

Import LDAP user data to wiki
Hi! I've got a strange problem. I've read a lot, but couldn't find anything, that was helping me. The LDAP-Authentication works well (after some starting troubles) ... when a user logs in, then the user is created in the wiki-database as well, that's good.

1. But is there a way, to import ALL LDAP users to the wiki? Thus, I can see on the userlist site in the wiki all LDAP users, which are able to log in, even those who haven't been logged in yet? Maybe there is a way in combination with another extension?

2. And is there a way, to automatically import the basic LDAP data of a user to his usersite, like Realname and email? Therefore the usersites of the users, who haven't logged in yet, wouldn't be that empty.

I already thought about writing a php script, which inserts the users in die usertable in the wiki DB ... but I'm afraid of destroying the consistency of the DB.

I hope you can give me some hints to achieve that.

thanks -- widi


 * Unfortunately, that is probably the only way to do it. If you really want to do this, I'd right a php script that uses MediaWiki to add the users, don't manually mess with the database. The SSL auto-authentication hook is probably a good starting ground for figuring out how to do it; you can ignore everything except for the part that actually creates the users. --Ryan lane 22:44, 30 June 2007 (UTC)

Hi, is there a way to create an account for each user in the ldap annuary now ? Maybe a solution has been designed since june 2007... Thanks --Teriblus 11:10, 13 May 2008 (UTC)


 * I don't think I understand your question... --Ryan lane 21:20, 13 May 2008 (UTC)

Oops sorry, I'm french. I would like to create a MediaWiki account for all registered users in LDAP including those wich have never been logged in on the wiki. Is it better now ?.. Thanks --Teriblus 10:30, 14 May 2008 (UTC)


 * I don't plan on supporting this any time soon. This would require things like scheduled tasks (cron, windows task scheduler, etc), as you'd have to keep it up to date. Also, it would require the deletion (or renaming) of accounts, and the renaming of accounts when they have been modified in LDAP. This isn't exactly an easy feat, and it doesn't really add much as far as I can tell. --Ryan lane 21:49, 19 May 2008 (UTC)

Another preferences problem
Everything works great for me except the preference pulling, i think (via the $wgLDAPdebug option) i have narrowed it down to it doesn't pull preferences. i have the following line at the end of the LDAP options in localsettings.php: $wgLDAPRetrievePrefs = true; but for some reason this is still returning false: $this->printDebug("Retrieving preferences",1); $entry = @ldap_read($ldapconn, $userdn, "objectclass=*"); $info = @ldap_get_entries($ldapconn, $entry); $this->email = $info[0]["mail"][0]; $this->lang = $info[0]["preferredlanguage"][0]; $this->nickname = $info[0]["displayname"][0]; $this->realname = $info[0]["cn"][0]; $this->printDebug("Retrieved: $this->email, $this->lang, $this->nickname, $this->realname",2); #} I'm not very patient so after posting this i continued to try to fix it. i found that this was also returning false: #if ( isset($wgLDAPRetrievePrefs[$_SESSION['wsDomain']]) && $wgLDAPRetrievePrefs[$_SESSION['wsDomain']] ) { $this->printDebug("Setting user preferences.",1); if ('' != $this->lang) { $user->setOption('language',$this->lang); } 		if ('' != $this->nickname) { $user->setOption('nickname',$this->nickname); } 		if ('' != $this->realname) { $user->setRealName($this->realname); } 		if ('' != $this->email) { $user->setEmail($this->email); } 		$saveSettings = true; #} i commented out the check blocks and preferences are reported as pulled and after my second edit, they are being populated in wiki, tho preferred language is coming back empty as such: Retrieved: eberlec@ .com,, Christopher Eberle, Christopher Eberle Setup is mediawiki 1.9.3, IIS6, mysql 4.1, PHP 5.2.2, windows 2003 standard I have changed the specialuserlogin.php as suggested and here are the settigns from my localsettings.php (incase you need them):

 * /me pokes you in the - you are using the wrong syntax for this option, and the option is documented at Extension:LDAP_Authentication. This option, like most options, are defined on a per domain basis. A good way to ensure your options are correct is to never use external documentation for how to configure this plugin. External documentation almost always seems to be completely incorrect. Usually the external docs were written for an older version of the plugin. Options have changed since then.


 * BTW, the "Fetched username is not a string" part is something most people don't configure. It isn't a bug; I guess I should make the message a little clearer. --Ryan lane 03:35, 13 May 2007 (UTC)

Username / Real Name question
I'm tackling LDAP authentication for the first time. I've managed to connect and authenticate, logging in with my LDAP username. Ideally, I'd like to login to an account named after LDAP real name, eg. having authenticated with username "johns", the registered account name is "John Smith" instead of "johns". Is this possible? I'm using the following configuration fragment (version 1.1d).

require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array( " " ); $wgLDAPServerNames = array( " "=>" "  ); $wgLDAPSearchAttributes = array( " "=>"uid" ); $wgLDAPBaseDNs = array( " "=>"o=Gla" ); $wgLDAPEncryptionType = array( " "=>"false" ); $wgLDAPDebug = 7; $wgMinimalPasswordLength = 1;


 * Well, if you have an attribute in LDAP that is the same as the real name, then yes, it is possible. For instance, if the entry's cn value is "John Smith", you can change:


 * $wgLDAPSearchAttributes = array( " "=>"uid" );


 * to:


 * $wgLDAPSearchAttributes = array( " "=>"cn" );


 * This way, the user can log in with "John Smith" instead of "johns". Also, btw, if you don't want to use encryption, set:


 * $wgLDAPEncryptionType = array( " "=>"false" );


 * to:


 * $wgLDAPEncryptionType = array( " "=>"clear" );


 * The plugin defaults to TLS encryption if the setting isn't defined, or if it is set to an incorrect value (for protection purposes). However, if this is working for you, set that to "tls", or remove the entry, since TLS is much better than clear. --Ryan lane 22:41, 30 June 2007 (UTC)


 * But in this case, username will look like "John smith" instead of "John Smith" which is not correct. And the main idea was to let users use their login name everywhere, and in a wiki too. There is a hook that calls for a function that extracts user name. Why can't extracted name be used as wiki user? That would be perfect.

LDAPAuth for 1.10?
I try to use LDAPAuth for MediaWiki 1.10... it works with

$wgLDAPEncryptionType = array("D Name"=>"clear");

but not with

$wgLDAPEncryptionType = array("D Name"=>"ssl");

I get Failed to bind as xxusernamexx when I use ssl... - any idea?


 * Ok - it works fine ;) I forgot the LDAP-Cert :-/ -- 07:57, 24 May 2007


 * I am using LDAPAuth and MediaWiki 1.10 and am still having issues when I have $wgLDAPEncryptionType = array("D Name"=>"ssl");

I have the LDAP-cert imported and working as far as I see. Here is an example of my config

require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array( "test" ); $wgLDAPServerNames = array( "test"=>"ad.test.lan" ); $wgLDAPEncryptionType = array ( "test"=>"ssl" ); $wgLDAPSearchAttributes = array ("test"=>"sAMAccountName" ); $wgLDAPBaseDNs = array ("test"=>"dc=test,dc=lan" ); $wgLDAPSearchStrings = array ("test"=>"TEST\\USER-NAME" ); $wgLDAPProxyAgent = array ("test"=>"cn=user,ou=test,dc=asynchrony,dc=lan" ); $wgLDAPProxyAgentPassword = array ("test"=>"password" ); $wgLDAPRetrievePrefs = array( "test"=>"true" ); $wgMinimalPasswordLength = 1; $wgLDAPDebug = 3;

I get Binding as the user and than Failed to bind as username. If I don't use ssl everything works fine......HELP! -- 27 Aug 2007


 * Are you sure SSL is enabled on your AD server? Does your web server trust the AD server's CA? Does the fully qualified hostname of the AD server match the CN on the certificate? Try using TLS instead of SSL, it should die in the connect method instead of the authenticate method. To see the error messages coming from the LDAP calls, remove the "@" character from before the function calls; the errors should show up in your web server or php error logs.


 * I recommend testing using a command like:
 * ldapsearch -Z -x -D "username@DOMAIN" -W -b "dc=YOUR,dc=DOMAIN" -H ldap://ad.test.lan (sAMAccountname=*)
 * (notice that -Z tells the command to use startTLS, if you want to try it using ldaps, remove the -Z, and change ldap://ad.test.lan to ldaps://ad.test.lan) --Ryan lane 00:33, 28 August 2007 (UTC)

PHP warnings
With the latest version on MW 1.10 getting the following PHP warnings: [Mon May 28 21:59:59 2007] [error] [client ...] PHP Notice: Undefined index:  wsDomain in ..../extensions/LdapAuthentication/LdapAuthentication.php on line 669, referer: http://.../w/Special:Preferences [Mon May 28 21:59:59 2007] [error] [client ...] PHP Notice: Undefined index:  wsDomain in .../extensions/LdapAuthentication/LdapAuthentication.php on line 673, referer: http://.../w/Special:Preferences [Mon May 28 21:59:59 2007] [error] [client ...] PHP Notice: Undefined index:  wsDomain in .../extensions/LdapAuthentication/LdapAuthentication.php on line 677, referer: http://.../w/Special:Preferences This comes from a failure to check for isset($_SESSION['wsdomain']) in the relevant code (3 spots I've found).

I just finished setting up LdapAuthentication.php version 1.1e with MediaWiki 1.93. After getting the login to work with TLS & SSL to work and the debug info turned on, I see these warnings after successful login:

... Notice: Undefined index: mail in /var/www/wiki/mediawiki-1.9.3/extensions/LdapAuthentication.php on line 354 Notice: Undefined index: preferredlanguage in /var/www/wiki/mediawiki-1.9.3/extensions/LdapAuthentication.php on line 355 Notice: Undefined index: displayname in /var/www/wiki/mediawiki-1.9.3/extensions/LdapAuthentication.php on line 356 Notice: Undefined index: cn in /var/www/wiki/mediawiki-1.9.3/extensions/LdapAuthentication.php on line 357 Retrieved:, , , ...

The warnings go away if I remove the setting for $wgLDAPRetrievePrefs.


 * This should be fixed in 1.1f (currently in SVN, but stable) --Ryan lane 13:18, 20 August 2007 (UTC)

Real AD Group Synch
I needed a real Group Sync to get the LDAP Extension work with the "Group_Based_Access_Control" Extension. I wrote this method and add it to the Class. I call in in the "authenticate" method. It does a real syncronize between AD Group Membership and the Wiki UserGroups. (Note: The Group Name size is limited by wiki database)

04.06.07 by Punisher: [mailto:punisher@e-workstation.de E-Mail]

function syncGroups($username){ $aLDAPGroups = $this->userLDAPGroups; $userID = User::idFromName($username);

if(($userID == 0)||(count($aLDAPGroups)== 0)) return; $u = User::newFromName($username); $aOldGroups = $u->getGroups;

// Adding new Groups for($i=0;$iaddGroup($aLDAPGroups[$i]); }           // Remove old Groups for($i=0;$iremoveGroup($aOldGroups[$i]); }           }	    $u->saveSettings; return; }


 * Huh? I've tested the plugin against active directory, and it seems to sync groups just fine. Is there something specific not working in the plugin? --Ryan lane 22:32, 30 June 2007 (UTC)


 * I actually found a bug in group sync, thanks to bug reports from other users. You may want to try this again. --Ryan lane 13:17, 20 August 2007 (UTC)


 * Thanks for this code, works great! I simply added it at the start after the variable initializations, and then called it with:

// LDAP Group Synchronization $this->syncGroups($username);
 * just before the "//Retrieve preferences" line. Syncs our LDAP<->Wiki groups perfectly. --Andrew Hodder 17:28, 19 February 2008 (UTC)

Creating a sysop user after configuring LDAP
My WikiSysop user account seems to be locked out now that I've set up MediaWiki to use LDAP authentication and I can't create a WikiSysop user in our LDAP directory. Can I make my own LDAP username a sysop user somehow? The instructions under Adding WikiSysop seem to be for doing so before setting up LDAP; however, I've already gotten LDAP configured.


 * Nevermind, I found the instructions on the Help:Setting user rights in MediaWiki page and that helped me figure it out.

HTTP Basic Authentication
I modified the extension to use HTTP Basic Authentication, if available. I tried to make it be an AutoAuth plugin, like SSL Auth is in this extension now, but I'm willing to bet it's not 100% right. You'll find a diff against SVN trunk below.

Problems authenticating usernames with underscore character(s)
I installed the LDAP Auth extension and have it working in MediaWiki 1.7.1 and Windows 2003 Server. The problem I have is that authentication does not work with usernames that include an underscore ("_"). After googling around, it looks like it is normal for MediaWiki to convert underscores ("_") to spaces (" "). Is there any workaround for this? Or, will I have to make sure any AD user that needs Wiki access has a username without any underscores? :( Please see my included debug output below... Anyone else have this issue :)? Your help is appreciated! Entering validDomain User is using a valid domain. Setting domain as: exampledomain Entering getCanonicalName Username isn't empty.

 * Well, the plugin doesn't currently support this. You may be able to add support for this into the authentication method, similar to how the plugin allows users to lowercase the username. Thing is, no matter what, you can either have users that have underscores, or spaces, not a mix of the two, because the wiki is always going to change underscores to spaces. The plugin unfortunately has no way of changing that. Sorry I couldn't be more help. --Ryan lane 22:30, 30 June 2007 (UTC)

Returned Groups not returning my Returned groups :)
I'm having a similar problem as the "Nested Groups option not working" guy. Ldapauthentication.php works fine prior to adding group based restrictions. When I add the "#group based auth" section to my config, AD users in the allowed group can no longer authenticate. However, the users that logged in prior to group based restriction were added to the users mySQL table and they can still successfully authenticate although they are no longer in the allowed group.

cat LdapAuthentication.php | grep "'version'" 'version' => '1.1f (alpha)',

Here is my conf: require_once( "includes/LdapAuthentication.php" ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array( "DOMAIN" ); $wgLDAPServerNames = array( "DOMAIN"=>"frodo.domain.com legolas.domain.com" ); //this place is run by true geeks $wgLDAPSearchStrings = array( "DOMAIN"=>"DOMAIN\\USER-NAME" ); $wgLDAPUseSSL = false; //not recommended but OK for testing $wgLDAPEncryptionType = array( "DOMAIN"=>'clear' ); // this is needed in >= 1.1c $wgLDAPUseLocal = true; //allows mysql db driven auth (default Root user) $wgMinimalPasswordLength = 1; $wgLDAPRetrievePrefs = true; $wgLDAPUpdateLDAP = array( "DOMAIN"=>"false" ); //disables mediawiki from updating LDAP $wgLDAPDebug = 3; //debugging $wgLDAPBaseDNs = array( "DOMAIN"=>"dc=domain,dc=com" ); $wgLDAPRequiredGroups = array( "DOMAIN"=>array("cn=wiki-sysops,dc=group,dc=domain,dc=com") ); $wgLDAPGroupUseFullDN = array( "DOMAIN"=>true ); $wgLDAPGroupObjectclass = array( "DOMAIN"=>"group" ); $wgLDAPGroupAttribute = array( "DOMAIN"=>"member" ); $wgLDAPGroupSearchNestedGroups = array( "DOMAIN"=>false ); $wgLDAPSearchAttributes = array( "DOMAIN"=>"sAMAccountName" );
 * 1) LDAP FUN!!!
 * 1) $wgLDAPRetrievePrefs = array( "DOMAIN"=>false ); // this is needed in >= 1.1c
 * 1) group based auth

Here is the debug log:

Entering modifyUITemplate Allowing the local domain, adding it to the list.

Look at my 2 lines that start with "Returned groups:". It appears that the search string is returning results, however it's not listing the groups. When there are multiple groups, the second Returned Groups: line has a bunch of commas, ie:

Returned group:,,,,,,,,

When I turn on nested groups, it also cycles the same groups multiple times. I've read this has happened to other users as well. 6/26/07 15:45 PST

EDIT-i had the wrong OU defined. this has been resolved.

Allow certain department numbers
How would I do a search for department number ("departmentnumber") or a group of them in LDAP and restrict the login using those numbers? Thanks


 * If you want to limit login by an attribute like department number, you can use search based options, like so:

$wgLDAPRequireAuthAttribute = array( "mydomain"=>true ); $wgLDAPAuthAttribute = array( "mydomain"=>"departmentnumber=331" );


 * Say for instance, you wanted to have multiple department numbers, you could use the following syntax:

$wgLDAPRequireAuthAttribute = array( "mydomain"=>true ); $wgLDAPAuthAttribute = array( "mydomain"=>"|(departmentnumber=331)(departmentnumber=332)(departmentnumber=333)" );


 * Pretty much any valid LDAP filter works; notice however, that the plugin wraps around the filter (I'll try to fix this in the future in a backwards-compatible way), so make sure you take that into account.


 * As for groups, you can define groups however you like in LDAP, and then use group based login restrictions to limit users by group.


 * Btw, I didn't notice your post earlier because you stuck the question at the top. Please stick all new support requests at the bottom of the page. --Ryan lane 20:42, 9 July 2007 (UTC)

Needless search (IMHO)
I tried this, but it does not work as I expected. Please patch the getUserDN in a way it uses $wgLDAPAuthAttribute. With this you save a needless search.
 * 1) The $wgLDAPAuthAttribute does not not effect the initial user search - getUserDn -.
 * 2) It only works for the first (of n) result entries of getUserDN searches.
 * 3) The effect is another search after the binding. This is redundant!

I have three cn="jane doe"s in my LDAP, each with different mail addresses. I want only one mail domain to be allowed to log in mail=*@example.org. Jane Doe cannot log in, because getUserDN finds three jane doe, tries the first, fails, error, end. If getUserDN would work as I mentioned above, there would be only one search result: filter=(&(cn=jane doe)(mail=*@example.com)).

I now hardcoded the filter in my getUserDN to get it work quickly. I'm not a experienced PHP coder, otherwise I would send you a patch. :(

Passwords using §
Any user who uses a § in his password cannot login. Mediwiki is claiming that the password is wrong or has not been entered. Can I change that? Thanks


 * Does this work with LDAP Authentication turned off? I need to know if it is MediaWiki causing the problem, or the plugin. --Ryan lane 13:27, 30 July 2007 (UTC)

Local Username Munging and Local User Creation
Two issues:

Local Usernames are Munged
If you enable local authentication in addition to the LDAP auth, all usernames are still munged, which causes previously created local MW user accounts with upper-case letters in the middle of them to be unusable (i.e. StatBot). Moving the strtolower call in to the if {} block that runs only for DOMAIN logins resolves this issue.


 * Hmm, I never thought of this... (I haven't used local accounts since I transitioned to LDAP). I'm putting this on the todo list. --Ryan lane 13:30, 30 July 2007 (UTC)


 * I ran into the same problem today. Here's the fix:

Local Users are created with a blank "user_password" field
Only Domain user accounts should have a blank user_password field - Local users need to have the standard MW password hash. As-is, any local accounts created are unusable.


 * This bug must have creeped in recently. I know for sure that at some point in the past this was working properly. It sounds like I need to make some unit tests... I'm adding this to the todo list. --Ryan lane 13:30, 30 July 2007 (UTC)

 * Unless I'm mistaken, this bug duplicates the allowPasswordChange doesn't check for $wgLDAPUseLocal bug which is described (and patched) elsewhere on this page. I applied the Christian's suggested patch under that heading, and it appears to have more-or-less solved the problem with missing passwords for locally-created users. (As an aside, however, I'll note that it would be nice if the Domain dropdown list on the create account page didn't show the LDAP domain if remote password creation isn't enabled for LDAP.) --Dmdwiggi 20:46, 14 August 2007 (UTC)

Fixed in SVN
I've fixed both of these in SVN. Can you test it out to see if the fixes did in fact fix your problem?

getCanonicalName fix for Local and AD users
I downloaded the latest version from SVN and I noticed this addition in getCanonicalName :

if ( !isset( $wgLDAPUseLocal ) || !$wgLDAPUseLocal ) { //Change username to lowercase so that multiple user accounts //won't be created for the same user. $username = strtolower( $username ); }

I believe that is a clever step ahead in the solution of this issue.

The condition tested, thou, tests a "constant" for what concerns LdapAuthentication.php, since $wgLDAPUseLocal never changes its value given in LocalSettings.php

This test doesn't help those wikis that use both local (SysOps and Bots with a capital letter in the middle) and AD accounts (case insensitive).

I thought to modify the test condition this way:

if ( isset($_SESSION['wsDomain']) && 'local' != $_SESSION['wsDomain']) { //Change username to lowercase so that multiple user accounts //won't be created for the same user. $username = strtolower( $username ); }

This way I can have $wgLDAPUseLocal == True.

When I select the Local domain, I skip this test and capitalize the first letter without changing the rest. (done in the rest of the code not re-written here)

When I select one AD domain, I lowercase the user name, that for some reason arrives in getCanonicalName still with mixed lowers and caps.

I was curious to know why $this->LDAPUsername doesn't get set in my wiki configuration... that's why I made this change.

 * Ah, good catch. That most likely is the best logic. Its in SVN now. --Ryan lane 04:01, 23 August 2007 (UTC)

AD Group usage help
Hi, I need some help on how to set up this extension in the following way: we have two AD groups, for example "WikiUsers" and "WikiAdmins". I want to restrict the the usage of the Wiki for these groups, i.e.
 * If a user is in neither group, he cannot access the Wiki at all (well, except the main page and the login page)
 * If a user is in WikiUsers, he should get read access to all wiki pages (and, if possible, r/w access to his own userpage and to all talk pages)
 * If a user is in the WikiAdmin group, he has "full" rights to view/edit the wiki (obviously still restricted by "blocked" pages or the like)

Anyone care to give me a quick howto on how to set up the wiki like that? I'm an LDAP newbie, so any help would be much appreciated. I guess I need to create the respective groups in the wiki and map the two AD group to them, then set $wgGroupPermissions accordingly?


 * Yep, that would be it. I'm not sure if it possible to restrict edit access like you would like to do with WikiUsers, but I could be wrong. That is more of a MediaWiki permissions thing. --Ryan lane 19:02, 6 August 2007 (UTC)

AD/LDAP and wgGroupPermissions and Group Name length
I've created a group in my AD called "Wiki Administrators", and given that group sysop permisions with this line: $wgGroupPermissions['Wiki Administrators'] = $wgGroupPermissions['sysop'];

This doesn't work, because the DB schema allows only 16 chars in the Group name. I am added to the "Wiki Administ" group, which doesn't match, so I am not a sysop.

A work around for this was to shorten the name to Wiki Admins, but the DB schema should allow longer names or the LDAP Auth module should match in a different way.


 * I don't disagree, but this is a MediaWiki core thing. I've asked the developers before, but didn't get much of a positive response (schema changes are somewhat of a big thing). --Ryan lane 19:04, 6 August 2007 (UTC)


 * I'll take a look into making it match a different way (or I'll talk to the developers again). --Ryan lane 19:28, 6 August 2007 (UTC)

User gets added to groups, but is never removed
I am using the $wgLDAPUseLDAPGroups feature. At first, everything works fine... Users are being added to the MW Database, MW Groups are created, and users are put into groups, all according to LDAP. Now: When i Remove a user from a group in LDAP, it stays in all the groups in MW. I found that this is a bug in the code: $this->printDebug("Checking to see if we need to remove user from: $cGroup",1);                                if ((!$this->hasLDAPGroup($cGroup)) && ($this->isLDAPGroup($cGroup))) { $this->printDebug("Removing user from: $cGroup",1);

The Fixed line would be:                                if ((!$this->hasLDAPGroup($cGroup)) && (!$this->isLDAPGroup($cGroup))) {

I Am using the Version 1.1e right now, but found that the bug is still existent in 1.1f alpha. Keep the good work up, this Extension is GREAT!

Cheers: Thomas Gruber --17:52, 7 August 2007 (UTC)


 * Hmm, actually I'm not sure that is a bug. The logic looks correct; well, I actually do see a problem, but not what you are describing. Turn on debugging, and make sure that the "getAllGroups" function is returning your groups. If it isn't then the plugin can't remove the user from the group, because it leaves non-ldap mediawiki groups alone.


 * Which of course causes a bug I just noticed. If you delete a group from LDAP, that group still exists in mediawiki, and the plugin can't sync it (and hence, can't remove the user from the group). --Ryan lane 21:50, 7 August 2007 (UTC)


 * Hi there, i got the following from the Debug output:

Available groups are: bot,sysop,bureaucrat,global-it
 * When i remove a user from a group, it IS displayed correctly when returning the groups for LDAP, but the user is not removed from the Group in MW - oh and BTW: This is a AD I am trying to use. Thomas Gruber - 13:49, 8 August 2007 (UTC)


 * Well, thats the available mediawiki groups. Look for this string "Returned groups:", after seeing "Entering getAllGroups". Btw, can you post your configuration with all sensitive stuff snipped out? --Ryan lane 02:04, 9 August 2007 (UTC)


 * Hi again, sorry, that i did not answer a long time. Had Holidays :-). I pasted the Config and the complete Debug output (debug 3) into a file on my server. I think this would definately be too big (and this article is long enough already) -> http://tuxpower.org/~virusmaster/mediawiki-ldap-bug - at the moment i have the problem, that i cannot recheck the problem now, since i do not have access to the AD Server atm. But in the debug output i see no "Entering getAllGroups" which would indicate, that the function is never called in the first place.
 * --ThomasGruber 13:11, 10 September 2007 (UTC)


 * Actually, it looks like it isn't finding the user in any groups. If it doesn't find your user in a required group, it won't synchronize groups at all. You need to get group restriction working before you worry about group synchronization. Please upgrade to the newest plugin release; there is a bug in the version you are using that may be causing the issue. --Ryan lane 16:56, 10 September 2007 (UTC)

Any DLL Files needed?
I am using Mediawiki 1.9 running it on an XAMPP server on Windows XP. My LDAP is not working at all even after pasting the code from the configuration link from mediawiki help. Do i need to copy any ".dll" into the system32 folder in order to make it working?

Also, including LdapAuthication.php and making changes in the LocalSettings.php is all i need to make to LDAP running right ?

I need simple Authentication from my LDAP server as to confirming username and password. What all codes do i need to paste in the respective .php files Please help me on this .. thanks.

Also,When i click on Login button,nothing happens and a blank screen come up. Frustration creeping in.

Honestly, a little googling on your side is probably a good idea. I know there have got to be other people who have had to have ldap and ssl working with php on windows before.

 * Thanks for helping me on this Ryan

The LocalSetting.php is as follows: $wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['user']['edit'] = true;


 * 1) Prevent new registrations from anonymous users (Sysops can still create new account)

$wgGroupPermissions['*']['createaccount'] = false;


 * 1) Define the pages un-authenticate users can see. This is crucial.
 * 2) Otherwise, there's no way for people to login.

$wgWhitelistRead = array( "Main Page","Special:Userlogin","-","MediaWiki:Monobook.css"); $wgGroupPermissions['*']['read'] = false;


 * 1) Authenticate users from an Active Directory.

require_once('LdapAuthentication.php'); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array( "ASDF" ); $wgLDAPServerNames = array( "ASDF"=>"10.76.122.2"); $wgLDAPUseSSL = false; $wgLDAPUseLocal = false; $wgLDAPAddLDAPUsers = false; $wgLDAPUpdateLDAP = false; $wgLDAPMailPassword = false; $wgLDAPRetrievePrefs = true; $wgMinimalPasswordLength = 1; $wgLDAPSearchStrings = array( "ASDF"=>"ASDF\\USER-NAME" );

I have pasted the .dll files and made changes to the php.ini in the apache/bin folder as that is the path shown in http://localhost/xampp/phpinfo.php under Loaded Configuration File. The Line 165 in LdapAuthentication.php is 		//TLS needs to be started after the connection is made if ( $encryptionType == "tls" ) { $this->printDebug("Using TLS",2); //165-->	ldap_start_tls($ldapconn); }

return $ldapconn;


 * Please take a look at the official documentation... Most of your configuration settings are invalid. I swear. I have no clue where these old configuration settings are at, but when I find them, all of them are getting deleted, or I'm going to bitch at the person hosting them. This is a pretty common problem...


 * Notice that since you are not using the correct config setting for encryption that TLS is going to be used. Also, you should use the AD server's fully qualified domain name, not its IP address. If you ever plan on using TLS/SSL, the server's certificate name needs to match the server name used, and the client must trust the CA that signed the certificate. Encryption is generally a good idea if you can get it working. --Ryan lane 01:02, 16 August 2007 (UTC)


 * Oops.. i just got it after searching for LDAP+Mediawiki+Windows :)

To be frank documentation is pretty confusing.Which part of it should i use ?There are so many Code Snippets here that i dont know which one to use ! I'm running it on Windows XP,PHP 5.2.3(XAMPP Server),Mediawiki 1.9.3,LdapAuthentication v 1.1d There is no specific documentation for Windows XP. --Ankit.madan 03:57, 16 August 2007 (UTC)


 * The documentation isn't OS dependent. It is LDAP server dependent for the most part. Look at the configuration examples, and use the one that fits your environment. If you are using AD, and only have a single domain, use Extension:LDAP Authentication/Configuration Examples.


 * Notice that the main documentation page's explanation of options should be used to ensure that the options you are using have the correct syntax, and do what you expect them to do.


 * Also notice that there is user provided information about how to configure windows Extension:LDAP Authentication. I don't use Windows as a web server (Linux is free after all, and I use OSX as my main desktop...), so it is hard for me to provide documentation on how to configure Apache/PHP/MySQL/OpenLDAP/MediaWiki on that platform; honestly, it is a little out of the scope of this documentation. If a user is kind enough to provide precise documentation after doing it, I wouldn't mind having an entire section devoted to it in the documentation, I'm just not likely to ever write it.

Yet another preferences problem
It seems I can authenticate as a domain user, but on Special:Preferences, email and real name are empty. I'm running Apache2, PHP5, MediaWiki 1.7, LdapAuthentication 1.1d.

LocalSettings.php:

require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPRetrievePrefs = true; $wgLDAPDebug = 4; $wgLDAPDomainNames = array( "DOMAIN" ); $wgLDAPServerNames = array( "DOMAIN"=>"pdc.domain.edu" ); $wgLDAPSearchStrings = array( "DOMAIN"=>"DOMAIN\\USER-NAME" ); $wgLDAPEncryptionType = array( "DOMAIN"=>"false" ); $wgLDAPUseLocal = false; $wgMinimalPasswordLength = 1; $wgLDAPBaseDNs = array( "DOMAIN"=>"dc=domain,dc=edu" ); $wgLDAPSearchAttributes = array( "DOMAIN"=>"sAMAccountName" ); $wgLDAPAddLDAPUsers = false; $wgLDAPUpdateLDAP = false; $wgLDAPMailPassword = false;

And the debug output:

Munged username: Jscott Entering authenticate Entering Connect Using TLS or not using encryption.

 * Please read the documentation. Most of your configuration options are wrong. Almost every configuration option is specified with the domain in question. Specifically, you do not have "$wgLDAPRetrievePrefs" set correctly, and the plug-in considers this to be set to false. BTW, options are set to false by default, so explicitly setting options to false isn't necessary. --Ryan lane 13:56, 13 August 2007 (UTC)

MS LDAP Authentication from LAMP setup
is MS Active Directory domain authentication possible using LAMP? Specifically can i use Linux/Apache to authenticate users on MS active directory? I dont have the possibility to install wiki on IIS/windows however i am using MS Active Directory. I tried some configs but logging always fails.


 * Yep. This is supported. I'd imagine a decent amount of people are doing this. Notice that AD will not allow unencrypted binds by default. AD requires the use of some type of encryption (which is kerberos by default -- unfortunately the plugin doesn't currently support kerberos authentication). If your AD server does not have an SSL certificate installed, TLS/SSL binding is not possible, and will cause logins to fail. Turn on debugging to see if encryption is the issue. Also notice that openldap by default will require the AD server's certificate to be trusted, and the server name to match the certificate name. Please see the appropriate PHP/openldap documentation to enable this correctly; if you don't care about the trust, and only care about the encryption, you can turn off the trust setting in openldap. Notice that information on how to do this is in the user provided information section of this article. --Ryan lane 14:01, 13 August 2007 (UTC)

Connecting to Global Catalog
I have gotten the extension working and authenticating using AD, but I wonder how to connect to the global catalog to authenticate. I would assume from the debug log that the connections use the standard ldap (389) and ldaps (636) ports. I saw a reference to the GC in the documentation but never how to actually connect (if I missed it, my apologies). When I add the :3269 (port for secure GC connections) to the server name it no longer allows me to bind. We have a main domain, and then several sub-domains. For instance, sub1.domain.com, sub2.domain.com... Also each subdomain then has several DC's. My problem is that only the GC can authenticate people from sub1, sub2, sub3, etc...  I can't list the servers from the other subdomains because I don't have the privileges to connect. Is there a way to choose the port to connect to or am I going about this wrong?? --Ctbarber 16:05, 14 August 2007 (UTC)


 * The global catalog is the AD server that hosts it. You will still use either port 389 or 636. AD should take care of the rest for you. --Ryan lane 00:56, 16 August 2007 (UTC)

Restricting groups from AD
Is it possible to restrict the groups the are pulled into mediawiki from an AD other that by using the GroupBaseDN?

The problem is that we have a large AD that contains many groups which have the same CN and the sAMAccountNames of these groups is not unique within the first 16 characters.

What I would like to be able to do is name a group in the AD that contains the groups that I would like mediawiki to pull in. Preferably it would pull all the sub groups as well. I have modified the code so getAllGroups just returns the groups I want but I still need to restrict the groups the user is in to those returned by getAllGroups based on the long name (DN).


 * You'll have to come up with some method of doing this. If your group names aren't unique within the first 16 characters, mediawiki won't be able to tell the difference. As I mentioned elsewhere on this page, I'll take a look into trying to get the character limit increased.--Ryan lane 13:13, 21 August 2007 (UTC)


 * I've talked with the core code developers, and there is now a bug in bugzilla regarding it. I'm hoping it'll be put in place for 1.12. --Ryan lane 16:51, 4 October 2007 (UTC)

Updated to MediaWiki 1.10, cant create new users
I updated from MediaWiki 1.7.1 to 1.10.1. When a new user tries to login, the following error appears: .. .. Authentication passed Entering setPassword Wiki is set to not allow updates

Internal error There was either an external authentication database error or you are not allowed to update your external account. ..

Now with the update, I assume localsettings.php and LDAPauthentication.php should not have been changed. That is those files remain the same. Should something have been changed here? Should something in SpecialUserLogin.php be changed?

Thank you very much Polo 08:42, 23 August 2007 (UTC)

OK, fixed it!!

Edit the LDAAuthentication.php script

change $user->setPassword; to $user->mPassword; (round about line 695) change return false; to return true; in the else if path in the setPassword function. (round about line 367)

 * What version of the LDAP plugin are you using? This was fixed quite a while ago. You probably need to upgrade. --Ryan lane 16:53, 23 August 2007 (UTC)

I also had the exact same problem with mediawiki 1.11 and thankfully your suggested code changes resolved the issue. I tried the latest 3 versions of the plugin and all gave a 'password incorrect' error. Debugging showed the error 'unable to start tls'. reverting back to an old version of the plugin and making the suggested code changes suggested by polo resolved my issue. - Anna


 * Reverting back worked because the older versions didn't throw an error if tls failed, which is a very bad thing. Now you think you are using encryption, and you really aren't. You need to figure out why TLS failed. You can try SSL, and see if that works for you. Either way, reverting back isn't really a fix. --Ryan lane 16:45, 4 October 2007 (UTC)

Problem with ProxyAgent and LDAPWriter using encrypted passwords
The documentation shows storing the passwords for the Proxy Agent and LDAP Writer in the LocalSettings.php using SHA encryption. When I try to specify the passwords this way, I get errors on binding inside the  function (called from  ) and the   function. If I change the configuration to plain-text passwords, everything works properly.

I am using MediaWiki 1.10.0 on PHP 5.1.6, with LDAP Authentication Plugin 1.1e. Is there some configuration setting or step that I am missing to make SHA-encrypted passwords work?

Thanks... Pcorreia 19:18, 23 August 2007 (UTC)


 * I can't remember the last time I did this. I usually just use a user who has very few privileges. --Ryan lane 03:32, 24 August 2007 (UTC)

WikiSysop user
I've added a WikiSysop user to the LDAP server as directed, but when I log in as WikiSysop I don't have sysop privileges. As it turns out, when I log in as WikiSysop the first time after turning on LDAP authentication, a new user is created in the MediaWiki database named Wikisysop (note the lowercase 's'). This user does not have sysop privileges. I have tried it with  set to both true and false, and I get the same result both times. Here's my LDAP WikiSysop user:

dn: uid=WikiSysop,ou=ServiceAccounts,dc=mydomain,dc=net objectClass: account objectClass: simpleSecurityObject uid: WikiSysop description: Wiki administrator account userPassword: (withheld)

Am I missing something? Does anyone have this (a WikiSysop user in LDAP that automatically gets sysop privileges) working with MediaWiki 1.10.0 and LDAP Authentication Plugin 1.1e?

Pcorreia 20:10, 23 August 2007 (UTC)


 * Well, actually, I don't recommend putting WikiSysop in LDAP. I recommend creating a regular user with the LDAP plugin disabled, and giving it sysop and bureaucrat rights, then enabling the LDAP plugin. You can also turn on $wgLDAPUseLocal temporarily, and log in with WikiSysop and do the same. Essentially, once the plugin is enabled, WikiSysop is never used again. --Ryan lane 03:35, 24 August 2007 (UTC)

Scoping down LDAP search for (&(member=*)(objectclass=group))
Well, doing this search on our AD is suicide - we would NEVER want a list of all our LDAP groups - we have over 3000. So how about this patch that scopes the search down to all the user's LDAP groups (which will definately hit) and all existing MW local groups, pulled from $wgUser->getAllGroups - which should yield all groups that we could ever want to compare anything to for this particular session:


 * This is a good solution to the problem (...actually, it is far better than the solution I was thinking of). Thanks for the patch, I'll be including this in the next release. --Ryan lane 17:00, 10 September 2007 (UTC)


 * I believe I've fixed this problem in 1.1g. I actually didn't include the patch, but I've added $wgLDAPLocallyManagedGroups, which allows the plugin to not have to check to see if a group is an LDAP group or not. So, now getAllGroups is simply not called unless $wgLDAPGroupsPrevail is enabled, which doesn't need to be unless you are using one of those (insecure) access control plugins.


 * Notice that the default behavior of the group synch stuff slightly changed. bot, sysop, and bureaucrat (which are always considered to be part of $wgLDAPLocallyManagedGroups) will sync normally, but never have members removed (unless you remove them manually). All other groups that are not part of $wgLDAPLocallyManagedGroups will have members added/removed normally. --Ryan lane 21:19, 21 September 2007 (UTC)

Protest vote about lack of "auth" category?
Fair enough - and much appreciated. I don't really think LDAP (or any of the other security related extensions) belongs as an "interface" type either, but for now it was the only one that even maybe fit (no access --> no interface), and of course, that alone proves the point that we need some new categories. There is an on-going discussion at Template_Talk:Extension. Please feel free to add your ideas. Egfrank 14:21, 11 September 2007 (UTC)


 * It looks like there is a category called User identity, which contains all of the auth plugins. I think this is probably fine. --Ryan lane 18:54, 21 September 2007 (UTC)

Problem after update to 1.11
Hello,

I just updated MediaWiki to 1.11 and am having some problems with the LDAP extension. I just updated the extension to 1.1f. Here is a sample of my configuration (that worked on 1.10):


 * 1) BEGIN ALL LDAP CRAP

// Active Directory LDAP Authentication require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin;

$wgLDAPDomainNames = array( "MYDOMAIN" ); $wgLDAPServerNames = array( "MYDOMAIN"=>"mydomaincontroller.mydomain.edu" ); $wgLDAPUseLocal = false; $wgLDAPEncryptionType = array( "MYDOMAIN"=>"clear" ); $wgLDAPRetrievePrefs = array( "MYDOMAIN"=>true ); //<- this is how to do it $wgMinimalPasswordLength = 8; $wgLDAPSearchStrings = array( "MYDOMAIN"=>"MYDOMAIN\\USER-NAME" ); //BINDING


 * 1) GROUP CRAP

$wgLDAPRequiredGroups = array( "MYDOMAIN"=>array("cn=wikiusers,ou=ntfs groups,ou=enterprise,dc=mydomain,dc=edu") ); $wgLDAPGroupUseFullDN = array( "MYDOMAIN"=>true ); $wgLDAPGroupObjectclass = array( "MYDOMAIN"=>"group" ); $wgLDAPGroupAttribute = array( "MYDOMAIN"=>"member" ); $wgLDAPGroupSearchNestedGroups = array( "MYDOMAIN"=>false ); $wgLDAPBaseDNs = array( "MYDOMAIN"=>"dc=mydomain,dc=edu" ); $wgLDAPSearchAttributes = array( "MYDOMAIN"=>"sAMAccountName" );
 * 1) DNs in $wgLDAPRequiredGroups must be lowercase, as search result attribute values are...

/** $wgLDAPUseSSL = true;   //Commented out because these options use syntax $wgLDAPUseLocal = false;    //for 1.0 and below (and are hence incorrect) $wgLDAPAddLDAPUsers = false; $wgLDAPUpdateLDAP = false; $wgLDAPMailPassword = false; $wgLDAPRetrievePrefs = true; */

//FOR DEBUGGING ONLY $wgLDAPDebug = 1; //for debugging $wgShowExceptionDetails = true; //for debugging MediaWiki

Now keep in mind the above worked fine in 1.10. After updating I get the error:

Incorrect password entered. Please try again.

I have had several people try their passwords and everyone gets the same message. When enabling debugging I get the following:

Entering validDomain User is using a valid domain. Setting domain as: MYDOMAIN Entering getCanonicalName Username isn't empty. Munged username: Acook001 Entering authenticate Entering Connect Missing LDAP support; please ensure you have either compiled LDAP support in, or have enabled the module. Failed to connect Entering strict. Returning true in strict. Entering modifyUITemplate

I'm not sure why it's saying: Missing LDAP support; please ensure you have either compiled LDAP support in, or have enabled the module. Any ideas?? Thanks!

 * Anyone still around in here?? HotMonkeyAC 16:13, 20 September 2007 (UTC)


 * I'm probably doing the check for the ldap module improperly... This is an issue with the plugin. You can comment out the return statement after the check in the code for now. In the next release I'll give a warning and won't cause the plugin to die (I'll try to figure out the proper way to detect the module too). --Ryan lane 19:00, 21 September 2007 (UTC)


 * Thanks for the reply Ryan. Do you happen to know where in the code I'd need to comment out?  Maybe you can provide a line number?  I'll let you know if it works.
 * -HotMonkeyAC 14:13, 25 September 2007 (UTC)


 * I changed this in 1.1g. If you upgrade, it should work for you. --Ryan lane 16:43, 4 October 2007 (UTC)

$domain Variable Empty?
I've been struggling to get this to move past the very first stage on my intranet wiki. I'm continuing to get these errors:

Entering validDomain User is not using a valid domain. Setting domain as: invaliddomain Entering modifyUITemplate

I added a "strlen($domain)" into the debugging code and it returned 0! I guess this means my $domain variable is empty. What does this mean? How do I fix this?


 * Does the login page have a selectable domain? If not, the plugin probably isn't configured properly. Post your config with sensitive stuff snipped out. --Ryan lane 19:02, 21 September 2007 (UTC)

Queries in Group Authentication
Hi Ryan,

I could do simple user authentication using LDAP.

But my aim was to authenticate and allow only a group of users to access the site. But i am unable to authenticate the user. Can you please tell me where am i going wrong.

The following is my code and the debug output.

$wgLDAPRequiredGroups = array( "domain"=>array("cn=group_admins,ou=groups,ou=abc,ou=bom,oc=ind,dc=ad,dc=abc,dc=com") ); $wgLDAPGroupUseFullDN = array( "ad.abc.com"=>true ); $wgLDAPGroupObjectclass = array( "ad.abc.com"=>"group" ); $wgLDAPGroupAttribute = array( "ad.abc.com"=>"member" ); $wgLDAPGroupSearchNestedGroups = array( "ad.abc.com"=>true ); $wgLDAPGroupNameAttribute = array( "ad.abc.com"=>"cn" )

Entering validDomain User is not using a valid domain. Setting domain as: invaliddomain Entering modifyUITemplate Username Received: Harshal m Username isn't empty. Munged username: Harshal m Entering authenticate Entering Connect Using TLS or not using encryption. Using servers: ldap://ad.abc.com Connected successfully Entering getSearchString Doing a straight bind Username is : Harshal_m Password is : userdn is: abc\Harshal_m Binding as the user Binded successfully Entering getUserDN Created a regular filter: (sAMAccountName=Harshal m) Using base: dc=ad,dc=abc,dc=com Fetched username is not a string (check your hook code...).

Entering strict. Returning true in strict. Entering modifyUITemplate


 * Do you have underscores in your username? Underscores cause problems because MediaWiki turns them into spaces. Essentially, the wiki is searching for a user with the samaccountname of "Harshal m", and can't find the user (and therefore can't use the DN in the search for the group). --Ryan lane 19:09, 21 September 2007 (UTC)


 * Thanks Ryan.Yes. I do have underscores as a part of the username. Can you suggest a workaround for the same. --Harshalm 11:13, 24 September 2007 (UTC)


 * I think someone else on this page has a workaround for this posted. This seems to be a pretty common problem. I'm going to see if there is a core-code way of fixing this... --Ryan lane 16:42, 4 October 2007 (UTC)

Setting DisplayName via AD
We have the LDAP connectivity to AD working well - except that it looks like the wiki real_name is being populated by our AD cn - which for us, is a login code (we are numbers not names in AD).

Ideally I'd like it to be a friendly givenName but am not sure what to change or set. I've tried changing the following code, but to no avail.

any help greatly appreciated

 * thanks, Callum Wilson 08:41, 25 September 2007 (UTC)

An additional note for those that have number based AD cn's, it is worth changing the Special:Listusers to include the user_real_name. This change is unlikely to affect non-LDAP auth sites with self-chosen usernames because they won't care about the users' real name. To do this:


 * open the file {wikidir}/includes/SpecialListuser.php
 * then change these bits of code
 * firstly, in GetQueryInfo, add user_real_name to the fields paramater
 * then in formatRow add in the realname display:

Doesn't work with 1.11?
I have a fresh install of Mediawiki 1.11. Two problems:

First: require_once( 'LdapAuthentication.php' ); doesn't work. I have to use require_once( './includes/LdapAuthentication.php' );. Without the ./includes/, I get this error:

Second: no matter what options I put in LocalSettings.php, I cannot get the LDAP authentication to do anything. Here is a sanitized version of my settings:

If I alter the code in /includes/LdapAuthentication.php to add some bad PHP, then I do get a runtime error. But it seems that no matter what I use with the above code, I never get anything on my wiki remotely resembling LDAP authentication.

If I replace wgLDAPServerNames with a bogus server name, I get no error.

Note well that despite setting the debug level to 3, I get nothing that would even slightly suggest any LDAP activities are going on.

Problem after moving to SUSE!!
I recently moved my Wiki from a Fedora box to a Suse 9 Enterprise Server box. I installed openLDAP, and compiled PHP --with-LDAP...everything went fine. HOWEVER, now when logging in I am getting an error that says "Incorrect Password". I debugged and this is what it's showing:

All of the configuration was copied from a working install. Everything is the same (Mediawiki version, database, etc). Is there a reason why I'm getting the error Failed to bind as MYDOMAIN\Acook001? Please help!

wgHook broken in 1.11 and 1.1g
I'm trying to get the wgHooks['SetUsernameAttributeFromLDAP'][] = 'SetUsernameAttribute'; to work but doesn't seem to work. First of all I got an error, stating that function SetUsernameAttribute in the LocalSettings.php file was suppose to return true. Added that code but it still doesn't work. Any ideas would be most appreciated.

Code: $wgHooks['SetUsernameAttributeFromLDAP'][] = 'SetUsernameAttribute';

function SetUsernameAttribute(&$LDAPUsername, $info) { $LDAPUsername = $info[0]['givenname'][0]. $info[0]['sn'][0]; return 1; }

I've also tried to analyze the output with $wgLDAPDebug = 7. It gave no indication that the hook were doing anything. Returning $LDAPUsername instead of 1 or 'true' doesn't work either. Other then that quirk I can't seem to get nestedgroups to work but you can easily work around that, tediuos, but it works.


 * Hmm. This should be working fine if you end with "return true;". Let me test this and get back to you. --Ryan lane 16:25, 4 October 2007 (UTC)

SSL has to be capitalized?
works, but  doesn't. Does SSL have to be capitalized? Should this be in the documentation?

Aren Cambre 16:21, 27 September 2007 (UTC)


 * No. It is definitely "ssl". If you put "SSL" it will use "tls" because "SSL" isn't a valid type (I don't do a tolower...). Most likely, if you change from using "ssl" to "tls", or don't define the encryption type (which will cause it to default to tls), it'll work for you. --Ryan lane 16:29, 4 October 2007 (UTC)

No need for email confirmation...
There is no need for email confirmation if the email address comes from a known-good source like an LDAP directory. Therefore, I'd like to propose: Aren Cambre 18:30, 27 September 2007 (UTC)
 * Autocreated users with email pulled from LDAP should have appropriate values in the user_email_authenticated field of the user table indicating the email is pre-confirmed. Suggested value is the timestamp of the most recent LDAP query where the user's personal info was last checked.
 * The user's personal info is checked on each LDAP authentication.
 * The real name, e-mail, and nickname fields are not editable by the user.
 * Looks like $wgEmailAuthentication may satisfy the first bullet point. Aren Cambre 18:57, 27 September 2007 (UTC)
 * I'd prefer the realname to stay editable because many corporate directories do odd things such as surname, firstname. just my 2p. --Callum Wilson 09:45, 28 September 2007 (UTC)
 * It would be nice if we had an option to choose that behavior. Aren Cambre 13:10, 28 September 2007 (UTC)


 * If these changes don't require manual database modification, I'll try to work it into the next version. --Ryan lane 16:31, 4 October 2007 (UTC)
 * It looks like the only one that needs anything done is #3. This will probably require core code changes. Notice that with this one, even if the user edits the field, the next time they log in, the field will be overwritten. I'll look into the core code changes, and I'll make a new config option to allow for preferences to be customized. --Ryan lane 19:20, 16 August 2008 (UTC)

Performance issues with 1.1g and MW 1.11.0
Hi,

I updated from MW 1.10.0 to 1.11.0 and LDAPAuth 1.0a to 1.1g today. Of course, I had to redo my LDAP config strings, but once that was working and I was able to login to the wiki, I immediately noticed a significant performance degradation.

I have a parallel wiki running on the same hardware that is at 1.10.0/1.0a and every page load takes literally three times longer on 1.11.0/1.1g! Most pages on 1.10 take 1 second to load, while it takes 3 seconds on 1.11.

After doing some digging, I realized that if I allow unauthenticated access to all pages, the performance is what I would expect: 1 second page loads. When I require authentication, the main and auth pages come up in 1 second, but once I actually authenticate via LDAP, I am back to 3 seconds per page.

I have done the routine steps of disabling all other extensions, and played with some of the LDAP settings, but haven't made a dent in the problem. Anyone have a thought as to what might cause this behavior?

-- Jonathan King


 * I can't imagine why this would happen, the plugin should only be called on login (unless you are using auto-authentication, like SSL Auth). I'll see if I can replicate this. --Ryan lane 16:38, 4 October 2007 (UTC)


 * Ryan and all, sorry for the false alarm. It turns out that the problem only occurred for IE7 users with WikEd enabled. Once disabled, performance returned to normal levels. --jonathan king

I'm still confused
I'm still getting to grips with LDAP itself, and this is also my first MediaWiki extension, so I'd appreciate some walkthrough for installing this.

I'm using Fedora DS (but that ought not to matter, as the protocol should be the same), MW 1.11.0 and LdapAuthentication 1.1g

Please feel free to ask questions about my set up to work out how to get this installed and working correctly.

 * OK, I did some reading and have a better understanding of our LDAP configuration, and armed with that knowledge, got it working just fine.

 * Glad to hear you got it working.


 * Yes, the password field in MediaWiki can change LDAP passwords, but you'll have to configure the plugin to have a user that is allowed to change passwords in LDAP (a little insecure); See Options for using LDAP as a user backend for more information. You can also control groups through LDAP; See Group options and Group synchronization. --Ryan lane 22:40, 24 October 2007 (UTC)

 * Remove:

$wgLDAPUseLocal = false; $wgLDAPAddLDAPUsers = false; $wgLDAPUpdateLDAP = false; $wgLDAPMailPassword = false;


 * As all of those are not even defined correctly, and if they were, false is generally the default for everything... Now, change:

$wgLDAPRetrievePrefs = true;


 * to:

$wgLDAPRetrievePrefs = array(   'exampleNonADDomain' => true    );


 * In fact, you should also try using false for that one, just in case, at first. --Ryan lane 15:36, 9 November 2007 (UTC)

I like to restict read/write support to certain pages or categories based on LDAP group members. Which Patch/Extension is supposed to work with this Extension? --TimHaegele 15:33, 11 November 2007 (UTC)

I am trying to do the same thing, and what I've got set up is at login it queries the AD for all groups the user is a member of and stores them in the session variable. Then, I use one of the Page Security plugins and change the part where it looks for if the user is a member of a group to check the array of LDAP groups. I store it in the session variable because it takes a long time to search the whole LDAP structure every time it's used. Also, it doesn't create a billion Wiki groups that map to AD groups. If anyone has any critiques of this method, please let me know. --Danielha 14:42, 12 November 2007 (UTC)


 * Apparently Extension:Group Based Access Control may. I added a patch in for them, so I'd imagine it works. Of course, I don't recommend any of these (for reasons why, read the top of that page, or the page of any of the access control plugins). Use a CMS, or a wiki that is designed for it. --Ryan lane 19:41, 15 November 2007 (UTC)

LDAP was working before Groups
I am trying to setup my wiki to work with LDAP and only allow certain users access based on the group they are in. I have it so that it is authenticating against AD and binding successfully for users. When I put in the code to try and restrict it to specific groups, it will not authenticate anymore. The debug statements contain: User is using a valid domain. Setting domain as: LDAPNAME Entering getCanonicalName Username isn't empty. Munged username: Sjordan Entering authenticate Entering Connect Using TLS or not using encryption. Using servers: ldap://ldap.server.com:3268 Connected successfully Entering getSearchString Doing a straight bind userdn is: sjordan@students.server.com Binding as the user Failed to bind as sjordan@students.server.com <-- if this fails, I try it again with sjordan@server.com which then binds successfully Bound successfully Entering getUserDN Created a regular filter: (sAMAccountName=Sjordan) Entering getBaseDN basedn is not set for this type of entry, trying to get the default basedn. Entering getBaseDN basedn is DC=server,DC=com Using base: DC=server,DC=com Fetched username is not a string (check your hook code...).

Entering strict. Returning true in strict. allowPasswordChange - Line 1 Entering modifyUITemplate

My local settings file contains:

require_once( "$IP/extensions/LdapAuthentication.php" ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDebug = 3; $wgLDAPDomainNames = array("LDAPNAME"); $wgLDAPServerNames = array("LDAPNAME"=>"ldap.server.com:3268"); $wgLDAPUseLocal = false; $wgLDAPEncryptionType = array("LDAPNAME"=>"clear"); $wgLDAPSearchStrings = array("LDAPNAME"=>"USER-NAME@students.server.com"); $wgLDAPSearchAttributes = array("LDAPNAME"=>"sAMAccountName"); $wgLDAPBaseDNs = array("LDAPNAME"=>"DC=server,DC=com"); $wgLDAPRequiredGroups = array("LDAPNAME"=>array("CN=* Dept - Information Technology,OU=Exchange Distribution Groups,DC=server,DC=com")); $wgLDAPGroupAttribute = array("LDAPNAME"=>"sAMAccountName"); $wgLDAPGroupObjectclass = array("LDAPNAME"=>"user"); $wgLDAPGroupNameAttribute = array( "LDAPNAME"=>"group" ); $wgLDAPRetrievePrefs = array("LDAPNAME"=>true); $wgShowExceptionDetails = true

i'm not sure why it is only showing that one group, when I look at memberOf using dsquery with the same filter, i'm receiving a lot more information. Thanks, Shane.


 * You are searching for users instead of groups. Try this:

$wgLDAPGroupAttribute = array("LDAPNAME"=>"member"); $wgLDAPGroupObjectclass = array("LDAPNAME"=>"group"); $wgLDAPGroupNameAttribute = array( "LDAPNAME"=>"cn" );


 * That should return groups instead of users. --Ryan lane 16:10, 13 December 2007 (UTC)


 * I made those changes, and it is still not returning any groups. Thanks, Shane

Proposition for wgLDAPRetrievePrefs
Recently i've successfully managed to implement LDAP authentification with local LDAP server, problem is that LDAP directory, for instance, doesn't have attribute displayName, but it has some other attribute to use instead of displayname. In the end i've hacked LdapAuthentication.php to suit my needs.

My proposition is to use an array to map predefined user prefrences variables (mail, preferredlanguage, ..) to their corresponding values in a LDAP directory, if that array is not defined then default mappings should be used. Is this doable? --Dodobas 14:37, 29 November 2007 (UTC)

SSL CA Issue
Hi. We have an SSL LDAP server which uses a non-standard CA. Is there a way to turn off certificate checking? Failing that, where is the CA registry kept?

Thanks.

Simsong 05:54, 4 December 2007 (UTC)


 * It depends on what type of OS your web server is on. If you are on a Linux system, you can define it in your /etc/openldap/ldap.conf file. If you want to turn off checking, you can set "TLS_REQCERT    never". If you want to add your CA, you can add it to the same file via "TLS_CACERT " and/or "TLS_CACERTDIR ". --Ryan lane 16:25, 13 December 2007 (UTC)

"Undefined offset" error
I get this error with 1.1g: PHP Notice: Undefined offset:  0 in /var/www/html/itwiki/includes/LdapAuthentication.php on line 1149 It shows up in the browser at login.

 * Your php configuration may have "display_errors = on" set. Set this to off (notice this is the secure thing to do anyway).


 * I do wonder about your configuration though... Why are you setting group options, if you aren't doing group syncronization, or group restriction? Also, notice that you should define "$wgLDAPSearchStrings" like this:
 * $wgLDAPSearchStrings = array( "DOMAIN"=>"DOMAIN\\USER-NAME" );
 * Notice the extra backslash. It is important. That may also fix your problem.

Interacting with Novell's eDirectory and usage on NetWare
To those who thought NetWare was dead, fear not! It took quite a bit of yelling at my company's 6.5 SP7 box, but I finally got it to run MediaWiki, and then to auth against eDirectory. But some changes to the LDAP Plugin are needed to drop the use of ldaps:// and actually pass a port number to the ldap_connect call (This patch is a HACK!): --- LdapAuthentication.orig.php	2007-12-08 22:30:08.000000000 -0500 +++ LdapAuthentication.php	2007-12-08 22:11:00.000000000 -0500 @@ -158,10 +158,12 @@ class LdapAuthenticationPlugin extends A 			case "ssl": $this->printDebug( "Using SSL", SENSITIVE ); $serverpre = "ldaps://"; +				$serverport = 636; break; default: $this->printDebug( "Using TLS or not using encryption.", SENSITIVE ); $serverpre = "ldap://"; +				$serverport = 389; } 		//Make a space seperated list of server strings with the ldap:// or ldaps:// @@ -169,16 +171,16 @@ class LdapAuthenticationPlugin extends A 		$servers = ""; $tmpservers = $wgLDAPServerNames[$_SESSION['wsDomain']]; $tok = strtok( $tmpservers, " " ); -		while ( $tok ) { -			$servers = $servers.

 * Sorry to hear you are stuck using netware ;). --Ryan lane 16:47, 13 December 2007 (UTC)
 * Hah, actually, I chose to stick with NetWare because I wasn't impressed with NSS support on Novell's OES1 iteration. The kernel module would randomly unload itself from memory, among other things, so I stayed with NetWare for this generation.  Next upgrade we do will probably be all Linux.  Besides, I kind of like NetWare....It's quirky and quite unique :) --Kumba 01:48, 17 December 2007 (UTC)

And I state this is a hack because I did this at 3am in the morning, and haven't touched PHP code really in-depth since 3.x, so doing anything more would probably be tricky. That stated, however, I think it'd be a nice addition to use the above as a template, and design a ports variable, say $wgLDAPServerPorts, which would take an array as an assignment wherein each array member represents an LDAP domain (or Novell Tree), and each domain is itself an array taking exactly two args: unencrypted server port and encrypted server port. That way, if $wgLDAPEncryptionType references ssl, then the secure port (def. 636) is used; else, unsecure (def. 389).
 * 389 is default for tls or clear, 636 is default for SSL. PHP should be doing this for you. You should only have to specifically define the ports if you use something non-standard, which makes this patch a little redundant. --Ryan lane 16:47, 13 December 2007 (UTC)
 * Should, but wasn't. I don't know what the core problem was, but even with the plugin's debugging turned on, I wasn't getting anywhere until I made the modifications highlighted in the patch.  Whether it's a NetWare-specific oddity or not, I'm unsure.  The funny thing is, Apache using ldaps:// forms works fine.  Of course, I also found that I wasn't granting browse rights for the CN attribute to the [Public] user at the root of my tree, which was breaking contextless logins as well.  I may have to try again now that I got that fixed.  As I saw this and the use of a proxy user as two different ways to get anonymous ldap browsing to work. --Kumba 01:48, 17 December 2007 (UTC)

Some interesting side-effects and other notes:


 * WikiSysop doesn't need to exist in eDirectory. Even though the bind against ldap fails, I guess if WikiSysop is in the local database, it somehow gets a non-zero result (or whatever result is being checked) returned and lets it log in.  Cancel that, it was something weird in my config causing that.  I wound up adding the Wikisysop user to my eDirectory tree in a top-level OU of its own, and creating a second "admin" domain specifically for the sysop login (I may put other wiki-specific users here, like bureaucrats and such), as my regular users are isolated in another top-level OU and need to stay separate.
 * You don't really need to add the wiki-specific users. I don't use any of those users personally, just create a regular user, turn off the plugin, promote the user, and turn the plugin back on. After that point, you won't need the default users ever again. You could also configure the plugin to pull groups from LDAP, and assign the proper permissions to certain groups. If you do that, you don't even have to do the more annoying stuff I mentioned previously. --Ryan lane 16:47, 13 December 2007 (UTC)
 * Yeah, all I have for now is just the wikisysop user in eDirectory. I may do what you suggest down the road and create a admin-level group in eDir and have my -admin domain auth against that to determine what users get what rights.  For a first run at setting up Wiki software, I'll probably stay with this until me and our DBA can get some content added, then start playing with it some more. --Kumba 01:48, 17 December 2007 (UTC)
 * Users don't have much of an ability to update stuff. Granted, I'm being pretty strict on allowing any change to flow back up into eDirectory, but I'd think it'd be possible for Wiki to be a little more flexible in this area.  Like say, adding the user to the local database if not already present BUT not using the database as an authenticator (I don't think $wgLDAPUseLocal and $wgLDAPAddLDAPUsers control it like this; it's either one or the other, not the mix I suggest), only to store preferences.  Not sure if this capability is present, as I only started playing with this yesterday, but I'd prefer this over a schema update and storing all the data in eDirectory itself.
 * This is what the plugin does by default. If a user doesn't exist in the database, it gets added automatically when they first login. Any preference they change is saved in the database. Any preferences pulled from LDAP automatically overwrite any locally set preferences. --Ryan lane 16:47, 13 December 2007 (UTC)
 * Well, when I tried updating someone's user profile data, I get an error back stating that I'm authing against an external database and preference saving isn't allowed. Either I have a variable disabled that shouldn't be, or it's because I'm communicating with eDirectory instead of a more normal LDAP implementation, like AD. --Kumba 01:48, 17 December 2007 (UTC)
 * If someone's up to it, writing an Identity Manager driver for MediaWiki would completely work around this.
 * If you're a touch old-fashioned, and like using all lowercase names in eDirectory, then make sure to use $wgLDAPLowerCaseUsername. It'll save some headaches, as eDirectory seems to be rather case sensitive on the DNs.
 * Novell actually has a wiki entry on their site for auth'ing MW against eDirectory, using this very plugin. But I suspect it's a bit dated: http://wiki.novell.com/index.php/Using_eDirectory_to_control_access_to_MediaWiki
 * I'm sure it probably is outdated. I'm not a big fan of people writing documentation in other places for this plugin, but I don't complain about that documentation since I'm able to update it myself. (if you look through the history, you'll notice I've updated it on occasion) --Ryan lane 16:47, 13 December 2007 (UTC)
 * On NetWare, you'll need to export your server's self-signed certificate via ConsoleOne (iManager may do this too) and place it into SYS:\PHP5\CERT (or wherever you have PHP), then restart Apache2 (AP2WEBDN, AP2WEBUP) so that PHP re-scans the cert folder and notes the new cert. Export it in DER format, and do NOT include the private key.  The cert is in the Security container at the top of the tree, in the CA object (if my memory is correct).
 * Updated Apache, PHP, and MySQL binaries can be found at http://www.gknw.net/. I advise visiting the forums too -- Günter is very helpful and knows lots about running this wacky setup on NetWare.
 * MySQL 5.0.45 has a bug in mysql_install_db, btw, so get 5.0.27 and copy the two *.sql scripts from the bin folder to 5.0.45's bin folder before running it.

Anyways, that's all I can think of for now. I'll add more if I discover something.

Nested groups not usable for $wgGroupPermissions
Hi there... I bet this is a known 'issue', but i am reporting it anyways since that feature would be VERY useful in our environment here...

The Problem: we use nested groups here, for example: (((qa-north + qa-south) = qa ) + prog-dept = tech) ...

Now we want to let all people of tech edit the wiki. At the moment we have to add ALL users of all the other groups to another virtual wiki access group (or tech directly) and then allow tech with $wgGroupPermissions to access various functions. Would it be possible (and clean to implement) to add a feature to add a wiki user to all the nested groups a user is in? (namely in this example tech, qa, and qa-north if a user is in qa-north)

This feature would be VERY appreciated.

--ThomasGruber 13:32, 8 January 2008 (UTC)


 * Yeah, this is a known issue. The reason this doesn't work is because my nested group code was written for group restriction, and for performance sake, the code stops searching ldap for higher nestings when it finds a required group. I'll need to rework the code for this to work. I'll put it on my todo list, but lately I've been very busy with other projects. --Ryan lane 16:19, 9 January 2008 (UTC)


 * Just had the same problem. Quick (and dirty) patching (against latest version) was to do the following:
 * add " var $nested_group_found; " in the global variables declaration,
 * add " global $nested_group_found; " at the beginning of the "authenticate" function,
 * in the same function as above, right after fetching User's groups (that makes line 394), add this line:
 * array_push($this->userLDAPGroups,substr($nested_group_found,3,strpos($nested_group_found,",")-3));
 * (here I use 3 because group name starts with "cn=..."
 * and finally, in the function that searches for the nested group, when it is found (line 1256), add:
 * $nested_group_found = $checkme;
 * As I said quite dirty. This works if the User is in only one of the groups you are looking for because as Ryan said, the code stops after finding the first one. But at least you can use this nested group for access control... Guimou

Cann't get LDAP group working
I am trying to setup my wiki to work with LDAP and only allow certain users access based on the group they are in. I have it so that it is authenticating against AD and binding successfully for users. When I put in the code to try and restrict it to specific groups, it will not authenticate anymore. The debug statements contain:

However, If you see above it do return the groups for the user but still it won't authenticate the user. Also, when I enable the group based restriction there are some PHP related warnings.

Please advice.

 * Notice that:

undefined variables: $mailpassword and $updateLDAP
function allowPasswordChange (line 586 of LDAPAuthentication.php) doesn't predefine these variables to a base case so depending on flow of execution through the function they are either undefined or set when tested. They should be set to something say "false" at the top of the function.


 * I'm assuming this is fixed? I'm checking to see if they are set or not. They don't need a base case. If they aren't defined, then it is the same as if they are turned off. --Ryan lane 21:51, 16 August 2008 (UTC)

 * Remove the following:


 * And set these options:


 * Notice that you are using AD-style straight binding. To search for a user in a group, you can't use the AD-style syntax, and instead have to use the user's full DN. When the plugin binds as the user, it will only get the user's full DN if you set "$wgLDAPGroupUseRetrievedUsername". Also, there shouldn't be a reason to lowercase the user's login. AD generally doesn't care so much about case. If you are still having issues, you can try adding that back in.

Not able to add Group based access control - Please help..
Hi, Like a few other I am also trying to set up group based permissions for my wiki. I started with adding LDAP authentication for n entire domain and that worked just fine.

Now I am trying to restrict access to only a group and am not bale to do it right.

these are my settings...

require_once( 'LdapAuthentication.php' ); $wgAuth = new LdapAuthenticationPlugin; $wgLDAPDomainNames = array("abc"); $wgLDAPServerNames = array("abc"=>"abc.xyz.com"); $wgLDAPEncryptionType = array("abc"=>"clear"); $wgLDAPSearchAttributes = array("abc"=>"sAMAccountName"); $wgLDAPBaseDNs = array("abc"=>"dc=abc,dc=xyz,dc=com"); $wgLDAPSearchStrings = array("abc"=>"abc\\USER-NAME"); $wgLDAPRetrievePrefs = array("abc"=>true); $wgMinimalPasswordLength = 1; $wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['user']['edit'] = true; $wgGroupPermissions['*']['createaccount'] = false; It does not work even if these 2 are commented $wgLDAPAddLDAPUsers = false; $wgLDAPUpdateLDAP = false;

Group Permissions

$wgLDAPGroupUseFullDN = array("abc"=>true );

$wgLDAPGroupUseRetrievedUsername = array("abc"=>true );

$wgLDAPGroupObjectclass = array("abc"=>"group");

Text file white list
Hi all... I'm in a situation where I can authenticate users via LDAP, but there are no appropriate LDAP groups which match the subset of users that I want to authorise for access to the wiki. What I need is for users to be authenticated by the LDAP extension, and then the logon should be rejected if their username does not appear in the white-list file. Does this sound possible? I'd be happy to jump in and make PHP changes myself, if someone could point me in the right direction. - Borofkin 04:27, 18 February 2008 (UTC)
 * Don't worry -- this has turned out to be a dead-easy modification. - Borofkin 05:58, 18 February 2008 (UTC)


 * You may be able to do this without modifying the code if you are using a search based configuration, by doing the following:

//Require the following additional search string. $wgLDAPAuthAttribute = array( "yourDomain"=>"!(|(uid=user1)(uid=user2)(uid=user3)(uid=...))"  );

Authenticating against AD and Local
Hello, I have my wiki setup to authenticate against AD. I would also like to set it up to check and see if the username is in a local list before allowing them access. I am willing to place all the names in an array and then check against the array. Or, place the users in the table and then only allow the user to authenticate if they are in the table. Any help would be great. Thanks, Shane


 * I have created an array of usernames and then a loop to check the user against that array, I placed this the getCanonicalName function. This is placed directly after the if statement to see if the username is not blank:

$LDAPallowedUsers = array("sjordan", "ebock", "ereger", "djoseph2", "ntennant", "jfarley1", "jraisovich", "araisovich"); $num_users = 0; foreach($LDAPallowedUsers as $num=>$users){ $matches = strcmp(strtolower($users), strtolower($username)); if($matches == 0){ $num_users++; } }   if($num_users == 0){ return 'XXYYXX'; }


 * This probably isn't the best way, since it still goes and does a check for XXYYXX user in the domain, but it is working. I wanted to define my array in the LocalSetting.php file, but when I try to do this, it causes the wiki to generate blank pages.  Anyone know what I have to do to create the array in LocalSettings? - Shane


 * I recommend restricting by AD groups instead. Notice, however, this is the same question that was asked above. Also, in response to the code posted as a solution: it'll work, but it probably a better idea to put this in the authenticate function, somewhere close to the top. --Ryan lane 18:28, 3 March 2008 (UTC)


 * I have tried a slight change which seems to accomplish what you are mentioning. I put a global variable $wgLDAPAllowedUsers in the authenticate function and added a statement just below the debug statement also in the authenticate function

global $wgLDAPAllowedUsers . . . if (!in_array(strtolower($username), $wgLDAPAllowedUsers)) { return false; } Then in LocalSettings.php I can put in the array of users I want. $LDAPallowedUsers = array("sjordan", "ebock", "ereger", "djoseph2", "ntennant", "jfarley1", "jraisovich", "araisovich"); Rbarton 15:26, 23 September 2008 (UTC)]]

Several Wiki Authentication (Something like SSO)
We have a Mediawiki 1.11 with the "LDAP Authentication Extension" installed. It works with an AD server flawlessly.

As we have several Wikis working in a Wiki family it would be great to authenticate once for all the wikis in the family. Otherwise one has to authenticate for each Wiki individually. The entire Wiki Family is running under the same domain.

Is there a way to tweak, hack or extend the environment so one can login once for several Wikis? I guess one has to fiddle with the user_token cookie. But I couldn't really find information about the process. Any help is highly appreciated. Thank you.


 * I haven't looked into this much. You may want to look at how they plan on doing this with SSO for wikipedia. I believe this is the extension in question. --Ryan lane 18:25, 3 March 2008 (UTC)


 * Thank you for the hint. CentralAuth is a SUL (Single User Login) effort. Dealing with the problem of people having accounts with different user names for different wikis. Thus it is about merging users. Single Sign On among Wikis may happen at a later point in time, is stated on the project pages.
 * The OpenID Extension is doing a Single Sign On though it doesn't make sense when you've got AD or LDAP...
 * Now that you point that out, it looks like you are completely right. No SSO, just merging as of now. OpenID/Shibboleth/WebSSO/Federation, and other approaches do SSO by authenticating in one spot, and passing an authentication token to all sites. This isn't the kind of thing that can be done with regular web authentication. You may want to look at using Federation (aka Shibboleth aka WebSSO). Federated authentication works along side LDAP authentication, and in many cases is simply an add-on to another product you are already using. You may want to take a look at Sun's suite of products (Sun Directory Server, Sun Access Manager), as they are free for use unless you want support. Access manager does SSO. You may also want to look at Atlassian's crowd authentication. There is already a MediaWiki plugin available for crowd auth. --Ryan lane 19:33, 14 March 2008 (UTC)

Copy E-Mail-Adress to wiki database when user logs in for the first time
Is there any configuration option that when a user logs in for the first time, the E-Mail-Adress is automatically copied to the wiki database?


 * $wgLDAPRetrievePrefs = array( "domainname"=>true );


 * This will pull the "mail", "preferredLanguage", "displayName", and "cn" attributes from the user's LDAP entry, if available, and populate the wiki database with those values. If you need to change the attributes, you'll have to do it manually in the code for now. A more customizable way of doing this is on the todo list for the next release. --Ryan lane 18:23, 3 March 2008 (UTC)

Added Group Based Permission and wiki stopped authenticating the user
I am trying to setup my wiki to work with LDAP and only allow certain users access based on the group they are in. I have it so that it is authenticating against LDAP and binding successfully for users. When I put in the code to try and restrict it to specific groups, it will not authenticate anymore. The debug statements contain:

However, If you see above it do return the groups for the user but still it won't authenticate the user.

My local settings file contains:

I am using MediaWiki 1.6.10 and LdapAuthentication 1.1g.

Please advice.

Groups from LDAP are displayed correctly in "returned group" but they don't find their way into Database
First of all thanks for the great work!

I want to authenticate with LDAP and synchronize then these Groups with my local Database. For testing i setted up a Domaincontroller with the Domain "Streichelzoo.de" and I created for example a User "Test2" who is in 2 Groups "asdf" and "Testgruppe". These Groups i get wonderfully displayed at the Debug Mode in "Returned Groups" but not in Effective Groups. Here is the Debug:

Handling empty searches
When LdapAuthenticationPlugin::getSearchString returns an empty string and smartcard auth is not used, the search is performed, but returns a result on my setup:

$entry = Array (    [count] => 1     [0] => Array         ( [objectclass] => Array (                    [count] => 2                     [0] => top                     [1] => OpenLDAProotDSE                 ) [0] => objectclass [count] => 1 [dn] => ) )

My quick and dirty solution is to change: (LdapAuthenticationPlugin.php@112)

//Search for the entry. $entry = @ldap_read( $ldapconn, $searchstring, "objectclass=*" );

to: //Search for the entry. if ( $searchstring != '' ) $entry = @ldap_read( $ldapconn, $searchstring, "objectclass=*" );

This gives me the correct behaviour.

...and just for completeness, I'm using version 1.1g on Debian and not using the smartcard stuff, if that helps.

Database updates not transactional on LDAP failures
When you have LDAP issues (be they configuration or otherwise,) the user accounts are written into the database regardless of whether they were written into the LDAP directory successfully. Ideally, this should be transactional. When developing my configuration I had to keep hacking out the wiki users from the MySQL tables.

Any update on this or the next stable version of the extension?


 * I've been so busy lately that I'm not expecting another release for a while. I'm sure it is probably doable, though. I mean, I do it in the SSL authentication portion of the code. You may want to look at how I'm doing it there, and see if you can replicate it. In fact, here is how I set the username to something other than what the user's smartcard has (in LocalSettings.php):

Been new user of LDAP Auth wich is working fine, but my rss feed are not working anymore, do we have a fix or workaround for that ?

Thanks a lot in advance.

you can get me per email at flamontagne@no_spam.noxent.com (need to remove the no_spam)


 * I'm not sure what to tell you, this plugin shouldn't affect that at all (and my RSS feeds are working just fine).

Images don't have any security
Hi, I'm not sure if I did something wrong with the set-up, but my images directory doesn't have any security on it, so you don't need to authenticate to view them. If you remove read permission from public users, this solves the problem, but then even authenticated users can't view the images. Obviously the issue is that the images are being viewed as flat files.

Thanks in advance for any help!


 * You need to use img_auth.php, otherwise Apache is handing out the images, and Apache isn't asking for authentication. --Ryan lane 22:20, 24 April 2008 (UTC)

Using Apache for image security
Hello, Is there a way to have apache handle the LDAP authentication but then have this extension grab the user name and log them into mediawiki after they have authenticated through apache? Much thanks in advance for your help!


 * Yes, but this extension is overkill if that is all you need. You might want to look at Extension:HttpAuth or one of the other extensions like it. This extension is useful if you want to do more than what Apache's module can do, and/or want to deliver a friendlier login screen. --Ryan lane 17:12, 28 October 2008 (UTC)

Problem with Underscores in User Names
Hiya All,

My users all have account names with an underscore in them e.g. Name_Surname.

When entering NAME_SURNAME I get this with debugging turned on:

Connected successfully Entering getSearchString Doing a straight bind userdn is: ENTERPRISE\Wayne humphrey Binding as the user Failed to bind as ENTERPRISE\Wayne humphrey Entering modifyUITemplate

However if I hard code my user name in LocalSettings.php e.g. Replace "ENTERPRISE"=>"ENTERPRISE\\USER-NAME", With "ENTERPRISE"=>"ENTERPRISE\\MyName_Surname",

I get a sucsefful login: Connected successfully Entering getSearchString Doing a straight bind userdn is: DOMAIN\MyName_Surname Binding as the user Bound successfully Entering getUserDN Created a regular filter: (=MyName surname) Entering getBaseDN basedn is not set for this type of entry, trying to get the default basedn. Entering getBaseDN basedn is not set. Using base: Couldn't find an entry Pulled the user's DN: Authentication passed Entering updateUser

so mediwiki stripping the underscore.

I have worked around this problem by adding the following to this extension:

In function getSearchString

add $username = str_replace(' ','_',$username);

bellow $tmpuserdn = $wgLDAPSearchStrings[$_SESSION['wsDomain']];

I know this is a dirty hack, so does anyone have any better ways in doing this?

Thanks,

 * Openssl/PHP don't use Microsoft's system trust. See someone's documentation on how to configure it for Windows. Notice that I don't necessarily support using "TLS_REQCERT never", but instead you should use "TLS_CACERTFILE <some path to your CA file>". Note that "TLS_REQCERT never" is better than authenticating without encryption. --Ryan lane 22:21, 26 June 2008 (UTC)

i've looked in many sites on google to solve this problem but with no success. the problem start when i use this line in the LocalSettings.php:

require_once( "$IP/extensions/LdapAuthentication.php" );

Someone got any idea?

help is appreciated.

thanks, ofer.


 * Are you putting this into the bottom of the file? --Ryan lane 22:17, 26 June 2008 (UTC)

Is objectclass test necessary?
In debugging, I kept seeing the getGroups function searching with the filter "(&(memberUid=NAME)(objectclass=))", even though I had set the $wgLDAPGroupObjectClass variable to an appropriate value ("posixGroup"). getGroups was then unable to find any groups, and the LDAP user was therefore unable to log in. I changed line 1408 of LdapAuthentication.php from this:

to this:

and now it works. getGroups finds the user's groups, and LDAP users in the required group can log onto the wiki without a problem.

My question here: do I really need the objectclass test? I can put it back if I need it, but it doesn't look like I really need it. - Jredmond 16:23, 4 June 2008 (UTC)


 * You don't need the objectclass if the attribute you are searching for only exists in groups. --Ryan lane 21:59, 26 June 2008 (UTC)

Patch to avoid crash when many groups
My organization has zillions of groups so that a call to @ldap_search crashed php (1.8Mb response when running the query in ldapsearch). Here is a patch that fixes it by only returning useful fields. BTW Thanks a lot for the great extension!

Changing username when creating local users
Hi, I'm having some trouble with the extension : the dn retrieved from LDAP is an email address, and it is used as the user name for local users. The problem is I can't use the built-in user right management with these users because when you type a name with '@' in it, the page thinks you're trying to edit a user from another wiki. Is there a way to use for instance the cn instead of the dn? (with users still logging using their dn). Thanks!


 * See this discussion for an idea of how you might be able to do this. --Ryan lane 22:12, 26 June 2008 (UTC)

Bugs when adding user
It seems to me there is two bugs in the function addUser since (at least) v1.1g. The first is near the lines 800-801 where a comma may be omitted if ( isset( $wgLDAPWriteLocation[$_SESSION['wsDomain']] ) ) { $this->printDebug( "wgLDAPWriteLocation is set, using that", NONSENSITIVE ); $userdn = $wgLDAPSearchAttributes[$_SESSION['wsDomain']]. "=" .        $username '. "," . ' $wgLDAPWriteLocation[$_SESSION['wsDomain']]; } else { and the second near the line 828 where it is considered the entire table if ( $wgLDAPRequireAuthAttribute [$_SESSION['wsDomain']]  ) { $values[$wgLDAPAuthAttribute[$_SESSION['wsDomain']]] = "true"; } Moreover, I don't see what should make these 3 last lines: ~ Seb35 13:08, 1 July 2008 (UTC)
 * must LDAPRequireAuthAttribute really be set to "true"/"false" (and not true/false - string vs boolean, see doc) ?
 * LDAPAuthAttribute is not a LDAP attribute in view of the doc but is an expression, I'm wrong ?


 * This code is probably the least used, which would probably be why it still has bugs; you are the first to report them, and this part of the code isn't part of my normal tests (I guess I'll start testing this as well now). All of the above looks correct, and as a matter of fact, the second part isn't even needed. You also pointed out an error in my documentation ($wgLDAPRequireAuthAttribute should take a boolean, not a string), which is now fixed. I'll fix all of this in the next release. --Ryan lane 14:07, 1 July 2008 (UTC)

Fatal error: Call to private method User::loadfromsession
Hi,

I'm trying to use smartcard authentication... I seem to be missing something pretty obvious, since the extension doesn't even get to the the stage of searching my directory... but what? The output in the browser looks like this:

Entering AutoAuthSetup. Allowing smartcard authentication. wgLDAPSSLUsername = Heinrich Opgenoorth wgLDAPSSLUsername is not null, adding hooks. Entering SSLAuth.

Fatal error: Call to private method User::loadfromsession from context '' in /var/www/mw/extensions/LdapAuthentication.php on line 1768

My LocalSettings.php contains the following lines:

require_once( "$IP/extensions/LdapAuthentication.php" ); $wgLDAPDomainNames = array("testLDAPdomain"); $wgLDAPServerNames = array("testLDAPdomain"=>"directory.fraunhofer.de"); $wgLDAPEncryptionType = array("testLDAPdomain"=>"clear"); $wgLDAPSearchAttributes = array("testLDAPdomain"=>"cn"); $wgLDAPBaseDNs = array("testLDAPdomain"=>"ou=".$_SERVER['SSL_CLIENT_S_DN_OU'].",o=fraunhofer,c=de"); $wgLDAPDebug = 5; $wgLDAPAutoAuthMethod = "smartcard"; $wgLDAPSmartcardDomain = "testLDAPdomain"; if (isset($_SERVER['SSL_CLIENT_S_DN_CN'])) { $wgLDAPSSLUsername = $_SERVER['SSL_CLIENT_S_DN_CN']; }

$wgHooks['SetUsernameAttributeFromLDAP'][] = 'SetUsernameAttribute'; function SetUsernameAttribute(&$LDAPUsername, $info) { $LDAPUsername = $info[0]['cn'][0]. " " . $info[0]['ou'][0]; return true; }

AutoAuthSetup;

The extension version is 1.1g, MediaWiki 1.12 (I also tried 1.10, same effect).

Any ideas welcome...

 * I think some things changed in later versions of MediaWiki. It looks like I've updated the local version of the LDAP plugin I'm using to work with newer versions of MediaWiki and didn't commit the changes. Please try changing the line:

Changing the line, the above error message is gone, but instead I get a MediaWiki internal error:

Auto Authentication (get rid of the login form)
Hi everyone

I would like to modify the login procedure. I want to get the username with something like the AUTH_USER variable of PHP, and bind to the AD with another account (having read/browse rights). Then I could retrieve info about the real user logging in and continue the normal flow of the LdapAuthentication extension. I think I will have to go deep in the PHP code ... anyone can help ?

Thanks

Michael     14 / 08 / 2008


 * I just added support for this in 1.2a; download the newest version of the plugin from svn, and be sure to also download LdapAutoAuthentication.php. Hopefully I'll have some documentation soon for various types of web authentication (Kerberos, NTLM, htpasswd, smartcard, etc.). --Ryan lane 22:21, 16 August 2008 (UTC)

Auto-auth (kerberos) examples?

 * Ryan, can you run through some real quick basics of setting up the kerberos (IIS integrated authentication, correct?) settings with the autoauth piece? I know that others have been chomping at the bit for this functionality, and I think I'm close, but I've not been able to make it work quite yet.  Thanks a ton for this; it's been pretty fantastic!  --Lane 04:19, 19 September 2008 (UTC)

Unable to use encrypted login
Hi, I'm trying to use this plugin on a Windows 2003 system running IIS, with PHP 5.2.3 and Mediawiki 1.12.0, and I cannot for the life of me get a TLS-encrypted login to work. Using clear, it works, but whenever I enable TLS, I get: Entering validDomain User is using a valid domain. Setting domain as: **** Entering getCanonicalName Username isn't empty. Munged username: **** Entering authenticate Entering Connect Using TLS or not using encryption. Using servers: ***** Using TLS Failed to start TLS. Failed to connect Entering strict. Returning false in strict. Entering modifyUITemplate Allowing the local domain, adding it to the list.

The "Failed to start TLS" bit there caught my eye. Is there some add-on I have to install to support TLS? I couldn't find anything that I'm missing either on this page or on php.net, so I'm hoping somebody can point me in the right direction here. --155.72.100.4 16:59, 30 July 2008 (UTC)


 * Are you using Active Directory (AD)? If so, it may not support TLS, or you may not have a certificate installed on the AD server. Try using "ssl" instead of "tls". Some AD servers will have ldaps enabled, but not tls over ldap. If that doesn't work, you need to ensure the AD server has a cert installed. If you do have a cert installed, you need to ensure that your client trusts the CA that signed the certificate. Some directions have been given by users for doing stuff like this. --Ryan lane 22:25, 16 August 2008 (UTC)

Removing domain selection from login screen
I'd like to remove the domain selection from the login screen because we only have one domain so select. Somebody knows how this can be achieved in the current version (MW 1.13.0, LDAP_Authentication 1.2a)? I don't see an Id on the select so I could hide it via CSS directly. If there's know option currently, can this be added in a future version please? Thanks. - Jan


 * I'll add the id; it'll be the same as the name. If you want to backport the change to your version of MediaWiki, you'll be safe. I'll add this to the todo list. --Ryan lane 18:25, 11 September 2008 (UTC)

Valid paramaters for $wgLDAPBaseDNs?
I have been working on getting mediawiki to auth against a w2k3 domain. used an above fix to restore the _'s that are present in all domain acounts, and also tested the php->ldap login outside of mediawiki with a script I found on http://www.gossamer-threads.com/lists/wiki/mediawiki/43821

The linked script works, as long as I set $ldaprdn = '' ; (this is the equivlanet of $wgLDAPBaseDNs I used ldp from the windows 2000 admin kit and know it should be dc=mycompany,dc=local but I dont know of any other options.

what would be a way to set this variable to nothing if the plugin does not require it, and to find out correct values for other required fields if it is?

I also notice that I am still getting a capital letter for the first part of my username. I see that caused problems in the past, and have tried posted solutions with no change. What is the current/correct fix?

What would really be helpful is getting more error info than simply "Failed to bind as mydomain\myuser"


 * If all you want to do is basic AD authentication, you don't need to know the basedn. All you need to know is the hostname of the AD server, and the domain name. See the simple configuration example for active directory. --Ryan lane 22:43, 3 November 2008 (UTC)

How about wgLDAPDeniedGroups?
Along with $wgLDAPRequiredGroups, would it be possible for you to create a complementary variable, $wgLDAPDeniedGroups, that excludes members of certain NT groups? It would be very handy to be able to express: "Everybody in group X, but not in group Y, can authenticate." Maiden taiwan 11:01, 18 September 2008 (UTC)


 * I'll think about adding this to the next release. --Ryan lane 22:45, 3 November 2008 (UTC)

Windows Integrated Authentication
Ryan, can you give a starting point to configuring this for Windows Integrated authentication? I'm assuming this will use a variation on the way it's set up to use smartcard auth, but I've not been able to get it to work as of yet.

Thanks! --Laduncan 21:17, 3 October 2008 (UTC)


 * I'll try to get some documentation out for this ASAP. I know a lot of people are really wanting this... Sorry for the wait! --Ryan lane 22:46, 3 November 2008 (UTC)

usedomain, useemail, getCanonicalName, and email confirmation
We successfully rolled out the LDAP extension to four MediaWiki sites, one of which is using auto authentication with the Apache server's mod_authnz_ldap. Thank you for this great extension!

We did run into three issues, two of which I fixed with small edits to LdapAuthentication.php, and one which is outstanding.

<ol> <li> We want users who already have LDAP accounts to be able to login without creating additional wiki accounts (the LDAP extension does this nicely) and we want users who do not already have LDAP accounts to be able to create new wiki accounts (the LDAP extension lets us do this also), but all of our wikis require email confirmation to be able to edit.

This is a problem for users who create new wiki accounts, because the LDAP extension removes the email address input from the create account page. Consequently users cannot provide an email address (and therefore cannot edit) unless they subsequently go to their preferences page.

Relatedly, we only have only one domain. We do use $wgLDAPUseLocal, for users who do not already have accounts in LDAP, but we _always_ want to try LDAP first, and fallback to wiki accounts. Again, the LDAP extension does this nicely. We just do not want users to see the domain selection input. We want the wiki to appear to the user exactly as it would if we were not using the LDAP extension, but their LDAP passwords work : )

To solve these problems, I commented out the "usedomain" and "useemail" lines in LdapAuthentication.php:

Then, because the domain form parameter is no longer submitted when users login, I had to set in manually in LdapAuthentication.php:

This works, but I would prefer that there were configuration options to have the same effect, without editing the LdapAuthenitcation.php source. For example, I wish there were configuration options to show the email input on the create account page, and hide the domain select input. I wish there were a configuration option to explicitly set which domain will always be used - like $wgLDAPAutoAuthDomain for non-automatic login : )


 * I'll add this to my TODO list. --Ryan lane 22:54, 3 November 2008 (UTC)

Or, I wish if there is only one domain configured, the LDAP extension would hide the domain select input and always use that one domain?


 * I think this was a wishlist of someone else, and I'm hoping to allow users to fix this by modifying their CSS. This is a fix that will require a core code change. --Ryan lane 22:54, 3 November 2008 (UTC)

<li> MediaWiki is case sensitive about usernames - it allows two usernames with the same letters but different case: e.g. Petervg and PeterVG. Consequently some of our existing MediaWiki accounts use mixed case: e.g. PeterVG

The LDAP extension's getCanonicalName makes usernames case insensitive by lowercasing them, and uppercasing the first letter. This means that when we want to fallback to local MediaWiki accounts, users with mixed case usernames, like PeterVG, cannot login.

I got around this be commenting out the strtolower call in getCanonicalName:

Again, I wish there were a configuration option to disable getCanonicalName, instead of having to edit LdapAuthentication.php


 * I'd recommend renaming users with mix characters to all lowercase. Unless this was fixed and I'm not aware of it, if a user logs in via ldap with UsErname, and Username, and UsernamE, three different accounts will be created. LDAP isn't checking case, but MediaWiki is; MediaWiki sees the users as three separate users. --Ryan lane 22:54, 3 November 2008 (UTC)

<li> Finally! I mentioned that we require email confirmation to edit the wiki. We do not want to disable email confirmation, but all of the email addresses in out LDAP database are already confirmed. So we do not want users with LDAP accounts, where their email address is retrieved by the LDAP extension from their LDAP account, to have to confirm their email. In other words, when the LDAP extension retrieves an email address from LDAP, we want it to mark that address as confirmed.

I have not got around to fixing this, so we currently have to tell all our users with LDAP accounts that they can use their LDAP password to login, but that they must then go to the preferences page and send themselves a confirmation email.

I wish there were a configuration option to mark email address retrieved from LDAP as confirmed : )


 * This should be on the TODO list; if it isn't I'll add it. --Ryan lane 22:54, 3 November 2008 (UTC)

After updating via rpm ldap auth failed when i press eidit

Automatic authorization using Windows AD to access MediaWiki
Hi everyone, I have been trying to get MediaWiki running on IIS, Windows Server 2003 with a mysql DB for a few weeks now. I have incorporated LDAP so users can manually login with their domain credentials. However i desperatly need to automate this process. Is there any current method to achieve this?? I have been browsing the web for ages now, and although people discuss the idea, there seems no be no notes on successes or failures! Is this totally unachievable at the moment??


 * Everyone seems to be asking this right now. I did add code to do this recently, but I don't have documentation written yet. I'll try to get some out soon. --Ryan lane 22:58, 3 November 2008 (UTC)

Authenticating automatically using REMOTE_USER
I just got it to work with php REMOTE_USER (after the web server authenticated the user using LDAP). I used the 1.2a version with Mediawiki 1.13.2; some bugs and notes:

1. Don't forget to download (and include) LdapAutoAutentication.php as well ( http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/LdapAuthentication/ )

2. In LdapAuthentication.php: function AutoAuthSetup has a check on the mediawiki version, this however results in the wrong hook being set, this was the one that worked for me: $wgHooks['UserLoadFromSession'][] = 'LdapAutoAuthentication::Authenticate';

3. In LdapAuthentication.php (about line 564): it says wgLDAPAutoAutoDomain, with should be wgLDAPAutoAuthDomain

4.In LocalSettings, make sure you have (amongst the other needed LDAP settings):

$wgLDAPAutoAuthDomain = " "; $wgLDAPAutoAuthUsername = $_SERVER['PHP_AUTH_USER']; $wgHooks['SetUsernameAttributeFromLDAP'][] = 'SetUsernameAttribute'; //This function allows you to get the username from LDAP however you need to do it. //This is the username MediaWiki will use. (>> for me this should be 'uid') function SetUsernameAttribute(&$LDAPUsername, $info) { $LDAPUsername = $info[0]['uid'][0]; return true; } AutoAuthSetup;

Regards, Gyuri

patch for UserLoadAfterLoadFromSession
Looking at the version in HEAD for MW 1.14: Don't you want that the other way around? If current code version is < 1.14, use UserLoadFromSession and fake the isLoggedIn?

(By the way, thanks many times for resolving that recursive load issue, and for having great sample code to look at in LDAP_Authenticate for other Auth developers.)

 * Yeah, looks like I have that backwards. I'll fix this ASAP. Going into the TODO. Thanks! --Ryan lane 23:14, 5 November 2008 (UTC)

Problem when there are many groups in the Active Directory
It looks like a bug - all of the sudden no user were able to log in to wiki.

After a little investigation we found: In the function getGroups, there is a code that bring all the groups from LDAP (why?). In the end of the function, before printing all the groups it calls "implode": $this->printDebug( "Returned groups:" . implode( ",", $groups ) . "", SENSITIVE ); $this->printDebug( "Returned groups:" . implode( ",", $shortnamegroups ) . "", SENSITIVE ); While there are too many groups in the LDAP, the function implode doesn't return, and the Wiki doesn't work. After removing the printDebug, the Wiki worked again. --D 09:00, 5 November 2008 (UTC)


 * Oops. Didn't think about that. I'll refactor the printDebug method to handle arrays so that I don't do this kind of thing unless debug is turned on. This is going on my TODO. Thanks for the bug report! --Ryan lane 23:16, 5 November 2008 (UTC)

setting up group-based login (AD) for idiots?
So far I have set up LDAP authentication to use AD usernames and passwords for logging in to the wiki. My settings file looks like this $wgLDAPDomainNames = array( "cc3-sbhs.internal"  );

$wgLDAPServerNames = array( "cc3-sbhs.internal"=>"sow-sr-001.cc3-sbhs.internal",    );

$wgLDAPUseLocal = true;

$wgLDAPEncryptionType = array( "cc3-sbhs.internal"=>"clear",  ); $wgLDAPBaseDNs = array("cc3-sbhs.internal"=>"DC=sow-sr-001");

$wgLDAPSearchStrings = array( "cc3-sbhs.internal"=>"USER-NAME@cc3-sbhs.internal",  ); lse $wgLDAPGroupUseFullDN = array( "cc3-sbhs.internal"=>true  ); $wgLDAPDebug = 3; This works fine so far, but I want to be able to restrict it to particular groups within AD. Unfortunately, most of the syntax for these configuration settings is baffling to me. Can anyone explain in fairly simple terms how to set this up? I can provide domain names, server names, group names etc. as required.

Thanks in advance --Carelesshx 15:07, 6 November 2008 (UTC)

Slight modification
Hey Ryan thank you so much for this extension. I've used with two employers. I had to make the following modification to get logins by group to work though. It's probably the way that AD is configured at my company, but only the first group was getting checked. The groups were all at the same level (attribute was memberOf) of the same search result (so only one entry, but multiple groups in it). In case anyone else runs into the issue here's what I did to make it work (code probably not greatest as I was just monkeying the PHP code, haven't really used PHP in a long time):

 * At some point in time I'm going to add memberOf support so that no one will have to do hacky stuff. I have to rework my group code some before doing so though. Hopefully it'll be soon and I'll fix your problem in a nice way ;). --Ryan lane 17:22, 11 November 2008 (UTC)
