Thread:Project:Support desk/MediaWiki with LDAP and Active Directory

I have installed MediaWiki on a Debian Wheezy System, and Active Directory on Windows Server 2008 R2. Now I am trying to implement a LDAP authentication. I have already tried many tutorials but none of them worked. I have downloaded the newest LDAP extension and edited my LocalSettings.php with these entries: The name of my Domain is "wikidom.de". I have already tried to subsitute all the AD fields with "wikidom.de" and also only with "wikidom". Both do not work.

Do I need to change other settings on the Windows Server?
