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:

Please follow the setup instructions for MediaWiki. After you have completed these, you should see LocalSettings.php.

thank you for your answer. They are on different domains actually, forum is on a abc.org and wiki is on abc.info, so the tld is different,

[NoeJeko]

This will not work for different domains as cookies aren't designed to be read across domains - just within a single domain.

You're correct. However, IIRC the Mediawiki-Extension CentralAuth uses some kind of mechanism to tunnel cookies to make exactly this possible.

Sorry, that is outside the scope of this product.

I didn't meant to completly integrate this plugin with CentralAuth but to get inspired by their methods of cross-domain-cookies which would be a great plus for sites who are running forum and wiki under their own domains.

At my job (not MyMMOGames), we use SAML tokens for cross-domain authentication. It can be done; I just do not have the time to devote to it for a community project like this for which I receive no compensation, heh.

ok changed to use a subdomain, same issue one thing (dunno if it makes a diff) is that wiki is not part of the forums folder, its set outside the forums folder, that ok?

getting mixed reports some people say it does allow them to login. will check further.

[NoeJeko]

Please check your cookie settings in vBulletin - make sure the cookie domain is set to ".domain.com".

[KingPin6]

* <myip>* Talk for this IP* Log in* Log out
