Past few days I have been looking for a way to have a real single sign on between
mediawiki and phpbb. I wanted the login state in phpbb to dictate that in mediawiki.
I got it working.
If you logout of phpbb, you logout of mediawiki, if you login to phpbb you are then logged
into mediawiki.
In mediawiki I have it checking the session of phpbb and doing an auto log.
BUT THERE IS A HUGE ISSUE:
I had to replace every instance of User (Class) in every mediawiki file with mw_User
because phpbb also has a user class.
I know a lot of people have asked about this. It is possible, but it is a ton of work.
This is nothing short of a hack, but for anyone interested, I though I would share.
