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...

When connecting with OpenLdap I had to add some connection options:

ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);

Thanks for the code, nice and simple and a great idea, seeing as guidance is hard to give apparently for this extension. Definitely not simple and straight forward to follow.

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?

slapd is the OpenLdap service, you won't need it if your using ActiveDirectory

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...
