[REQUEST] WP MediaWiki Single Sign-On

After scouring google and support forums for the past couple of days, I’m hoping someone here can help me. I’m trying to set up a three part site (Blog or CMS, forums, and wiki), all using the same login info for the users, and ‘single sign-on’ IE: Whatever part of the site you login to, you are logged in on all of them. I would prefer to use WordPress, BBpress, and MediaWiki.

I am not having any luck integrating with MediaWiki. The only information I can find is from WP 2, or from years ago. I had a somewhat working setup using WP, MW, and phpBB, but it wouldn’t login to MediaWiki, and phpBB has way more features than I’m looking for.

Does anyone know how I can have all three scripts use the same user database, and have site wide logins?

Thanks in advance,
Charles Murphy
