SSO for MediaWiki
A plugin to enable Single Sign-On (SSO) for MediaWiki. This is set up to use GodAuth but can be easily be modified for any SSO system. The HTTPAuth.php plugin is an alternative version that just uses a $_SERVER variable. It should be very easy to adapt.
Copy the file GodAuth.php into the /extensions/ folder. Then open up your LocalSettings.php file and add these lines at the bottom:
$wgAuthDomain = 'mydomain.com';
require_once('extensions/GodAuth.php');
$wgAuth = new GodAuth();
