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 3.8.x. For vB 3.7.x, please use the MediaWiki/vBulletin Single Sign-On 3.7 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:

To quote from my LocalSettings.php

 
# This file was automatically generated by the MediaWiki installer.
# If you make manual changes, please keep track in case you need to
# recreate them later.
#
# See includes/DefaultSettings.php for all configurable settings
# and their default values, but don't forget to make changes in _this_
# file, not there.
#
# Further documentation for configuration settings may be found at:
# http://www.mediawiki.org/wiki/Manual:Configuration_settings

Once you have installed MediaWiki, you will find that file has been created.

I hope this helps

I have this installed with vBulletin 3.8.4p1 and MediaWiki 1.15.1. It works well enough, but there's one tiny hiccup. Something related to Memcache is causing MediaWiki to forget about its extensions. I get an error like "Invalid tag extension name: myextension". Haven't yet found a solution to this, but I'm looking.

Be careful not to have anything within your vBulletin skin that calls back to MediaWiki by requiring LocalSettings.php. Bad things happen.

Ok, so my install of MW is a bit borked right now. I'm getting the blank page issue mentioned earlier and it actually started when I was using an earlier script to integrate VB with MW. After removing the previous hack (vbwiki pro) I've installed this hack according to the directions listed here but its still not working. After taking a look at some of the posts in this thread I'd like to get a clean and fresh localsettings.php file to work with since this is a bit over my head. Whats the best way to do that?

Once I've got it working well independatly from VB I'll take another look at installing this hack.

Ok, since things in my install were pretty messed up I deleted the localsettings.php file from the root and the /config directory. Then, I used the MW installer to create a new file using the settings I copied from the deleted copy. After that I was able to login using the standard MW systems. Then, following the directionsin the .txt file included with the mod I reinstalled the hack and it works now.

So, this was working well for a while but seems to have died after just a few minutes. If I try to rollback a change I get this response from MW.

You do not have permission to do that, for the following reason:
There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking.
Please hit "back" and reload the page you came from, then try again.

And if I try to edit the page I get this error.

Your edit has been rejected because your client mangled the punctuation characters in the edit token. The edit has been rejected to prevent corruption of the page text. This sometimes happens when you are using a buggy web-based anonymous proxy service.

Any tips?

Adding "php_flag magic_quotes_gpc off" to my .htaccess file corrected the above issues.

How do you add someone to a wiki usergroup? It doesn't appear to save them for some reason.

Has anyone tested this with vb 4.0 beta yet and the latest version of Mediawiki? I'd love to update but its not worthing breaking anything.
