Consolidating databases - opencart/phpbb3/mediaWiki (MySQL)

I am building a site that uses opencart as the main site with links to the wiki (MediaWiki) and the forum (phpbb3). I would like to consolidate everything so the user only has to log in once.

mySQL db.

How can I do this? I will be working with a clean db so no need for user migrations.




thanks

What you need to do is implement a single sign-on solution such as openid, CAS or oauth.  Check which one is supported by all 3 (they are usually supported via add-on modules).  Hopefully, there's one openid/cas/oauth implementation that can read from opencart's database.  If not, you need to construct a separate signup solution.

So there is no way I can tell it to use the same db  and share the user tables? Like use a different prefix except for the user stuff. Or edit the program to use the same content?

It should be possible, but that will likely mean the user still has to log on when he moves from opencart to the other site.  Unless, you also share the session database.  Using a single sign-on solution is really the way most people would handle such a requirement.

I'm having someone code the php to share the data and sessions.
