I guess I'll start with some background.

I've been trying to get a site running for some time that is based on Wordpress for the front end, with phpBB and Mediawiki both integrated into it, using phpBB for auth. Both phpBB and the wiki would be wrapped in the Wordpress header/footer. I had this running perfectly for a while using WP-United for WP/phpBB integration but the project was abandoned.

I tried doing this myself using a basic Wordpress plugin to auth to phpBB, which worked until I tried to nest MediaWiki inside the WP header. While WP is authing with phpBB there is a User class conflict between MW and phpBB. So basically, I could make any two of them work together, but not all three under the WP header. I tried several things including adding namespaces (I'm not a php developer so I didn't quite grasp it) with no results.

I just swapped out MediaWiki with Wikka Wiki. It will import the Wordpress header perfectly, but all of the methods for authing with phpBB are out of date and I don't have the skill to update them, as they're much more in-depth than the simple Mediawiki extension I was using.

My next step is to try Dokuwiki but I figured I'd ask here and get some answers while I'm working on it. I tried Wikka because it was advertized on one site as integrating well with other software.

So... I need a wiki engine that can auth to phpBB in a way that will be maintained.

I need the wiki software to play nice with Wordpress headers that are using phpBB user sessions.

I'd like it to maintain login status across phpBB/wiki as my WP/phpBB mod does.

Any insight is appreciated, thanks.
