Has anyone worked this out yet for UBB?
http://www.mediawiki.org/wiki/Extension:PHPBB/Users_Integration
Over at ubbcentral.com, I replied in the
Joining UBB with collab software thread to mention that I successfully integrate my ubb.t installation with
DokuWiki.
MediaWiki was overkill for my needs so I ended up using DokuWiki instead, but perhaps the SQL for user authentication will help?
