Extension talk:LDAP Authentication/LQT Archive 1

= Archive =

Due to limitations of MediaWiki structures and unidentified editor's limited patience, someone archived an earlier version of this discussion/talk page, as "it was getting way too long" - accuracy, continuity, and helpfulness be damned! Some archive contents of this discussion/talk page from ~2007-05-12 and earlier can be found (and contributed to!) here:

Archive 1 -- Peter Blaise peterblaise 10:02, 23 May 2007 (UTC)


 * Note that I archived it, and kept issues that were still open on this discussion page. It is very hard to keep track of things when a page is as long as the old one was. I understand that it breaks continuity some, but quickly finding things in what is essentially a support forum is a good thing. I'm probably going to make an FAQ from answers on the old discussion page, and this discussion page. --Ryan lane 19:32, 6 August 2007 (UTC)

= Requirements =

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

= I can't find the code! =

= Compatibility =

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)

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)

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 :)

The group "systems engineering" is a member of nca se wiki users. But I still can't login... I hope this is enough information.


 * 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

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)

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:

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

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)

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)

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:

...

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)

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.

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

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)

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)

 * Almost - The line
 * $username[0] = strtoupper( $username[0] );
 * needs to be outside the IF loop - local Wiki accounts still need to have the first character capitalized - otherwise users who enter their uname all lowercase in Special:Userlogin will not be able to login locally. Only the strtolower call should be inside the if LDAP block.

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)
 * ty. btw, great extension.  We use it on our Internal HelpDesk wiki against a W2k3 AD at St. Cloud State University.

 * 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!

 * 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.

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.

--220.225.64.6 07:30, 9 August 2007 (UTC)


 * I don't use XAMPP (and never have before). I also never use apache/php/mysql on Windows. Unless the current documentation on the content page can help, there is nothing I can do for you. 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.


 * Maybe someone else here can help you out? --Ryan lane 14:05, 9 August 2007 (UTC)


 * Thanks Ryan.. i have reached to the final step now .. things working now .. the error now coming is "start-tls]: Unable to start TLS: Server is unavailable in C:\xampp\htdocs\mediawiki\includes\LdapAuthentication.php on line 165" Though i am able to ping my LDAP normaly through the command prompt.


 * Also, how to get this contents block on the top of every page ? --Ankit.madan 07:21, 10 August 2007 (UTC)


 * Can you post your configuration, with sensitive stuff snipped out? --Ryan lane 14:03, 13 August 2007 (UTC)


 * 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:

Entering validDomain User is using a valid domain. Setting domain as: Domain Entering getCanonicalName Username isn't empty. Munged username: Jscott Entering authenticate Entering Connect Using TLS or not using encryption. Using servers: ldap://pdc.domain.edu Connected successfully Entering getSearchString Doing a straight bind userdn is: DOMAIN\Jscott Binding as the user Binded successfully Entering getUserDN Created a regular filter: (sAMAccountName=Jscott) Using base: dc=domain,dc=edu Fetched username is not a string (check your hook code...). Pulled the user's DN: CN=Jason Scott,OU=Techs,DC=domain,DC=edu Authentication passed Entering updateUser


 * 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)

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)

Polo 12:24, 23 August 2007 (UTC)


 * 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)

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:
