= 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

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!

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

Quick Answer!
Answer: See Extension:LDAP_Authentication

= Compatibility =

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)

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 :)

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...

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)

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

 * /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;

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?

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:, , , ...

Lines 354-357 contain: $this->email = $info[0]["mail"][0]; $this->lang = $info[0]["preferredlanguage"][0]; $this->nickname = $info[0]["displayname"][0]; $this->realname = $info[0]["cn"][0];

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

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)

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; }
