How to ask for support

There's a couple key pieces of info I always need:

1. The MediaWiki version you are using
2. The LdapAuthentication extension version you are using

I very often will need to see two other things when you ask for support, so you should have them prepared:

1. Your configuration, with sensitive stuff snipped out
2. The extension's debug log, with sensitive stuff snipped out

When you are trying to debug an authentication problem, you should always use the most basic configuration possible. For instance, if you don't have basic authentication working yet, you shouldn't have group restrictions or group synchronization enabled yet. I will generally ask you to disable these things when debugging.

Also, $wgLDAPUseLocal is almost never what you want to use. It's a frequent cause of configuration issues, and unless you really know what you are doing, it should not be set (or explicitly set to false, which is the default).

Most importantly of all: ensure you are using the newest version of the extension. From the extension distributor, that's the "master" version. If you are using git, just make sure you use git pull && git reset --hard origin/master. This is one of the more common cause of problems.

Hi! I installed the Extension on my MediaWiki 1.32 running on Xampp (PHP 7). Setup the configs as following:

$wgLDAPDomainNames = array(

  'MYDOMAIN',

);

$wgLDAPServerNames = array(

  'MYDOMAIN' => 'MYLDAPSERVER',

 

);

$wgLDAPEncryptionType = array(

  'MYDOMAIN' => 'ssl',

);

$wgLDAPSearchAttributes = array(

  'MYDOMAIN' => 'sAMAccountName',

);

$wgLDAPBaseDNs = array(

  'MYDOMAIN' => 'DC=manz,DC=lc',

);

$wgLDAPGroupBaseDNs = array(

'MYDOMAIN' => 'OU=DE,OU=RT,OU=User,DC=MYDOMAIN,DC=lc',

);

$wgLDAPUserBaseDNs = array(

'MYDOMAIN' => 'OU=DE,OU=RT,OU=User,DC=MYDOMAIN,DC=lc',

);

There is an actual domain name and the ip for the LDAP Server,however for privacy reasons I would like to hide them. It seems like there is a connection established, however the Extension can not find the user. Log tells me:

2019-03-04 10:22:34 WINWIKI x: 2.1.0 Couldn't find an entry

2019-03-04 10:22:34 WINWIKI x: 2.1.0 userdn is:

2019-03-04 10:22:34 WINWIKI x: 2.1.0 User DN is blank

I got it to work, the problem was actually that a proxy user was needed in order to do the search.

How did you configured your Proxy? Like in the docs?

$wgLDAPProxyAgent = array( 'testLDAPdomain' => 'cn=proxyagent,ou=profile,dc=LDAP,dc=example,dc=com', ); $wgLDAPProxyAgentPassword = array( 'testLDAPdomain' => 'S0M3L0ngP@$$w0r6ofS0meV@rie222y!', );

After authenticating with ldap, my users IP address still appears in the information bar and there is no "LOG OUT" link (The "LOG IN" link is still present).

An advice on what I am doing wrong?

MediaWiki 1.23.0 PHP 5.3.6 (apache2handler)

Hello! First: I have moved the thread to the extension talk page, it's better there to talk about the extension :) To your problem: The logout link will be removed by the Ldap Auth extension, that's right. The other things i can't answer, maybe someone other (maybe the developer) will do :)

My server has the same behavior. I'm usin 1.31.1.

I solve this problem loading my wiki inside a <div>. The logout button stay in other page.

If user wants to exit wiki, He clicks logout and the page is redirect to mainpage.

Anyone got this working yet?

Works just fine after upgrade from mw 1.31

I did not quite understand how the mapping works. We have a lot of Wiki AD Groups, e.g(Public_C and Public_E etc.)

How do I tell the config that I want one of that group to match another group in the wiki that is called different?

Looks like you cannot map groups if group names are different in wiki and AD.

When try to get LDAP working with AD I am getting this BadMethodCallException on the logon page when I try to log on.

I installed veresion 1.32 of mediawiki on Windows with PHP 7.3 enabled ldap. I kept the ldap setting the same as my previous wiki installation which used to work (version 1.24). However it does not look like the extension is loading?

My entry :

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

$wgAuth = new LdapAuthenticationPlugin();

When I get to the logon page it is not showing my ad domain which it used to show on the previous version?

Please try the new LDAP extensions. Major changes were made to authentication around MW 1.27.

Installed:

MediaWiki	1.25.2
PHP	5.5.9-1ubuntu4.11 (apache2handler)
MySQL	5.5.44-0ubuntu0.14.04.1
Apache2	2.4.7
LdapAuthentication	: REL1_25 2015-06-16T21:10:35 d4db6f0

 

Installed and configured MediaWiki without problems. Then I tried to change the login to LDAP. After hours and the use of the documentation I was not able to login. Is this extension still working? 

Here are my LocalSettings.php config: 

#LDAP Authentication
    require_once( "$IP/extensions/LdapAuthentication/LdapAuthentication.php" );
    $wgAuth = new LdapAuthenticationPlugin();
    
    $wgLDAPProxyAgent = array('EUROPE' => 'cn=mediawiki,dc=EUROPE,dc=LAN');
    $wgLDAPProxyAgentPassword = array('EUROPE' => 'password');
    
    
    $wgLDAPDomainNames = array( "EUROPE.LAN" );
    
    $wgLDAPServerNames = array( "EUROPE.LAN" => "dc1.EUROPE.lan" );
    # I recommend using a Global Catalog server for this.
    
    $wgLDAPSearchStrings = array( "EUROPE.LAN" => "EUROPE.LAN\\USER-NAME" );
    $wgLDAPEncryptionType = array( "EUROPE.LAN" => "tls" );
    $wgLDAPUseLocal = false;
    $wgMinimalPasswordLength = 1;
    
    $wgLDAPBaseDNs = array( "EUROPE.LAN" => "dc=EUROPE,dc=LAN" );
    # Example: If your domain is mydomain.internet.ca then you want to put in "dc=mydomain,dc=internet,dc=ca".
    
    $wgLDAPSearchAttributes = array( "EUROPE.LAN" => "sAMAccountName" );
    
    
    $wgLDAPRetrievePrefs = array( "EUROPE.LAN" => "true" );
    
    $wgLDAPPreferences = array('EUROPE.LAN' => array( 'email' => 'mail','realname' => 'displayname'));
    # This will automatically map the users e-mail address and full name from Active Directory to their account in MediaWiki
    
    $wgLDAPDebug = 3; //for debugging LDAP
    $wgShowExceptionDetails = true; //for debugging MediaWiki
    $wgDebugLogGroups["ldap"] = "/tmp/ldapdebug.log" ;

This is the debug log:

I tried a normal PHP login with this script and it works.  

<?php
// use ldap bind
$ldaprdn  = 'mediawiki'; 
$ldappass = 'mediawiki';

// connect to ldap server
$ldapconn = ldap_connect("EUROPE.LAN")
    or die("No connection to LDAP.");

if ($ldapconn) {

    // bind ldap server
    $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);

    // test binding
    if ($ldapbind) {
        echo "LDAP bind success...";
    } else {
        echo "LDAP bind failed...";
    }

}

?>

Please help me the problem is really frustrating and I worked on it for hours... 

Just for info: "mediawiki" is an existing windows domain user. I tried other users too and it still worked.

And most importantly: Why do I need kerberos or slapd as the documentation tells? Is the normal php5-ldap package not enough?

try switching to SSL, or clear text. If you are authenticating and the binding is failing (same as mine below) then we might be in the same boat. The extension works. I can vouch for that. If the ldap server you are authenticating to isn't authenticated by a real CA you might have issue. You'll need to add the public key certificate to your CA store.

I did the change and this is how my /etc/ldap/ldap.conf looks now

TLS_REQCERT     never

This is the change I did in the /var/lib/mediawiki/LocalSettings.php

$wgLDAPEncryptionType = array( "EUROPE.LAN" => "clear" );

And this the debug file. Still no success...

After hours of madness I finally get it working:

You have to install the required packages: Extension:LDAP Authentication#Installation

Then just follow this guide: http://ryandlane.com/blog/2009/03/23/using-the-ldap-authentication-plugin-for-mediawiki-the-basics-part-1/

Forget what configurations are written on the wiki page. If you get after the login a database error: Topic:Sshx994njzy3rs3l

"www.mediawiki.org/wiki/Topic:Sshx994njzy3rs3l" (if the link does not work)

I am a bit mad but happy now. This plugin costs to much time because of the missleading documentation.

Let's say that in my LDAP server I have a group called "trainers". Of all the members of that group there are a select few that are also in a group called "aces". In other words, all users that are in the group "aces" are also in "trainers" but not all "trainers" are "aces".

I have my MediaWiki set up so that you cannot create a new account and that only and all "trainers" are able to log in using LDAP Authentication. However, now I want "aces" to have SysOp privilege without the Bureaucrat manually granting each "ace" the privilege using the interface.

How do I go about doing this?

You can use group mapping and set group permissions. Smth like:

$wgLDAPUseLDAPGroups = array(
  'testADdomain' => true,
);

$wgGroupPermissions['aces']['edit'] = true;
$wgGroupPermissions['aces']['delete'] = true;
$wgGroupPermissions['aces']['move'] = true;

How do i set this up with Simple AD, I'm only 14, and am confused after trying for 3 days to install

I think it's been mentioned that this extension isn't compatible with Mediawiki versions above 1.27, could that be the source of your troubles?

Have an old Mediawiki Ubuntu server running Ubuntu 14.04, with MediaWiki 1.25, PHP 5.59 and mysql 5.7.23. This server was getting old and we wanted to add certain functionality past what 1.25 could run, so we spun up a new server running 18.04, transferred everything over and I was able to get the wiki up and running. It is now at MediaWiki 1.30, PHP 7.2 and mysql 5.7. My localsettings.php have not changed and as this is all internal I am running the encryption type as clear. I have the debug log set up and everything seems to be running correctly until

userdn is: user@domain

Entering getDomain

Binding as the user

Failed to bind as user@domain

I can access the ldap server as usual.

Any ideas?

did you installed the ldap module for php7.2

apt-get install -y php7.2-ldap

you can check it with a phpinfo()

spent some hours upgrading from mw v29 to v31 . without any changes to LocalSettings.php LDAP Authentication to debian 9 OpenLDAP server (slapd) works.

after reviewing my incomplete notes and apt install logs, the only thing I see we did was:

apt install php-ldap

our existing LocalSettings.php had:

require_once 'extensions/LdapAuthentication/LdapAuthentication.php';

$wgAuth = new LdapAuthenticationPlugin();

Note that the second require_once should not be needed.

thanks - i removed the second require_once and no issue logging in.
