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

Demo of plugin in action: MyMMOGames - Multiplayer Gaming and Media Community

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:

Reloaded wiki from scratch, built it from an empty database, and confirmed everything was working fine before added this mod. Added this mod by adding the few lines in the localsettings.php, uploaded the include files, and I keep getting this same error. New host is on Centos 5.3, PHP 5.3.0, MySQL 5.1.137.

Hmm, I'm wondering if it's because the new site doesn't have an actual domain pointing to it yet, and is only being referred to by IP address. (http://xxx.xxx.xxx.xxx/wiki). Perhaps everything is set up OK and when I actually move the domain over things will start working on their own. I can always hope.

[aciurczak]

No such luck. I moved over a domain so the wiki is being reference by an actual domain, and the error remains.

I'm having the same EDIT TOKEN problem as him, but I do not know how to do what you have suggested. Can anyone help me with that? I created a file called php.ini and php5.ini and typed in:

php_flag magic_quotes_gpc off

And then uploaded it to the WIKI root folder. But do I need to do anything else? There wasn't any other files named php.ini or php5.ini anywhere else on my server.

I think this is the last hurdle for me. Thanks in advance to anyone that can help.

Is your patch correct in Localsettings.php?

IE define( VB_SYSTEM_PATH, '' );

[SuperGLS]

Yes, everything works with this mod except for the ability to edit pages (any of the wiki pages).

I've actually since discovered a work around, but I don't know how smart it is. I changed the edit token information in the user.php file from

define( 'EDIT_TOKEN_SUFFIX', '+\\' );

TO

define( 'EDIT_TOKEN_SUFFIX', '+#+' );

I found this work around by looking at someone elses problems with integrating SMF and MW (rather than vB and MW). They ran into some problems with apostrophes ( ' ) turning into \\ but I haven't had the problem thus far.

Still, if I could get this working correctly I'd be happier I think.

For ref, my forum is www.elantraxd.com/forums and my wiki is www.elantraxd.com/wiki

Is there a way to disable the login screen when someone isn't logged in and simply display an error message on the wiki?

Right now if someone isn't logged in to vbulletin it displays the vbulletin login page. Instead of this, I want an error message brought up on the wiki saying something similar to "Please log in to the forum and refresh this page."

In addition, how can I make sure that only people logged in can see information the wiki (right now it seems the case, but I want to make sure).

This mod seems like the best option for integrating vB/Wikimedia. Thanks.

When I try to use the MediaWiki/vBulletin Single Sign-On and try to edit the MediaWiki pages I get this error from MediaWiki and I get Apache errors for PHP. If I do not use the Single Sign-On edits to the MediaWiki page go through fine.

Sorry! We could not process your edit due to a loss of session data. Please try again. If it still doesn't work, try logging out and logging back in.

I CANNOT edit the mediawiki or save preferences with the Single Sign-On installed. I did the /includes/User.php edit but I still cannot EDIT!

Open wiki/includes/User.php FIND:
PHP Code:
define( 'EDIT_TOKEN_SUFFIX', '+\\' );
Replace with:
PHP Code:
define( 'EDIT_TOKEN_SUFFIX', '+#+' );

Posted Solution on MediaWiki that does not work for me.
Assuming you get this error even when you do have a seemingly valid logon session:

Check if /var/lib/php5 is writable and not readable for user and world ( # chmod 733 /var/lib/php5 )
Check to see if your session.save_path value in php.ini is valid and writable to the webserver - PHP configuration.
Check to see if there is enough disk space.

After making changes restart Apache:

/etc/init.d/httpd restart

I get Apache errors for PHP:

This has to be set in the LocalSettings.php and has nothing to do with this mod. Have a look at the MediaWiki-Wiki.

How do you get rid of the PHP errors concerning the CWD error!?!?!?
