Integration with vBulletin - MediaWiki/vBulletin Single Sign-On

Overview:
This hack provides single sign-on capability for MediaWiki using your vBulletin users. You must ensure your cookie path in Admin CP is set to '/' for this to work. Also, I have not tested this if your wiki and your forums are on different subdomains - but as long as your have your cookie domain set properly it *should* work. This is not a user bridge - it is a complete single sign-on using your vBulletin user repository.

The install process has been extremely simplified in version 2.x of this product. You only have to edit LocalSettings.php, import a product, and change a setting in your Admin Control Panel. It's been completely packaged as a vBulletin product - unlike the previous hacked up version, heh. I didn't originally plan to release this so I designed it so it worked - not so it could be redistributed. I searched high and low for a functional MediaWiki bridge - almost bought NuHIT's product, and then realized it had been abandoned for over a year.

This hack no longer requires an edit to class_core.php.

I'll do my best to support it, but I can make no promises.

This thread is for discussion of this mod on vB 3.7.x. For vB 3.8.x, please use the MediaWiki/vBulletin Single Sign-On 3.8 thread

Also, if you use memcached - ensure you do not cache sessions. If you do, restart it at least once a week. If you don't, you'll end up with invalid session errors out of MediaWiki.

AuthPlugin was inspired by and modified from this existing MediaWiki Extension:

I think I discovered my problem, I run vbDrupal, and drupal uses "user" php sessions, but mediawiki uses file, and apparently loading vbulletin's core stuff to get the authentication from the cookies will sometimes (but apparently not always...) cause drupal to start a session preventing mediawiki from opening the existing session (containing important edit tokens, etc)

Sooo for now I think I'm going to have to use a regular authentication plugin forcing users to sign in twice Nice work though, maybe eventually I'll track down what makes drupal start the session, or try again when I get around to upgrading vbdrupal.

Thank you worked perfectly

Had the same problem and this worked great for me! Thanks for sharing

And thanks for the bridge, exactly what I was looking for! Keep up the good work

Hey guys - I'll try to get a version detection built in and automate this based upon version within the next couple of days. Thanks for pointing it out as we're not currently using MW 1.13.

It seems like you didn't set one of the directives in the Admin CP properly - or you didn't define VB_SYSTEM_PATH in LocalSettings.php

Changed the User::newFromName to initialize the $user object itself without replacing it... when it was replaced the calling function appeared to still have the old $user object which was giving an error.

In doing that I first load defaults, then set the name, set mFrom to name, call load, check if the user has a valid ID and if not add to the database, and then continue on.

In addition, I Found that the sysop groups weren't being removed when I removed someone from admin group so I added $user->removeGroup for both before then adding it again (or not) depending on the users vb group.

I'm not totally familiar with mediawiki's authorization process (I just installed it actually) so some of this may be redundant, or worse something could be missing....

At any rate it appears to be working if I find any problems I'll post here, I'm attaching my copy of AuthPlugin_vBSSO.php if anyone wants to use it.


Edit: Not working at this time, something is causing edit tokens (and maybe more) to not be correct during POST requests, still investigating

Seems to have fixed things for me as well.
