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.

(Note that I also have use a VPS, and the path on the server is similar to yours (/var/www/vhosts/entropiaplanets.com/httpdocs/w).

My LocalSettings.php has the following lines:

if( defined( 'MW_INSTALL_PATH' ) ) {
    $IP = MW_INSTALL_PATH;
} else {
    $IP = dirname( __FILE__ );
}

$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );

require_once( "$IP/includes/DefaultSettings.php" );
define( VB_SYSTEM_PATH, '/var/www/vhosts/entropiaplanets.com/httpdocs/forums' );
require_once( "$IP/includes/AuthPlugin_vBSSO.php" );

If you do not have the red line, add it, and change from entropiaplents.com to cromosdefutbol.com.

I have to admit that I really cannot guess as to the error regarding the includes of the AuthPlugin line, but see if my setup gives you something to work with. Feel free to post the results here.

Thanks for your help.

At the moment I have a different error above:

Parse error:  syntax error, unexpected T_IF in /var/www/vhosts/cromosdefutbol.com/httpdocs/mediawiki/LocalSettings.php  on line 30

We need to call the directory wiki? I have my directory called mediawiki

Got it work with my forum but when I access mediawiki out the following error lines

http://www.cromosdefutbol.com/mediaw...gina_Principal

Maybe it's easier if you post the contents of your localsettings.php file here. Just substitute the security information (servername, account, password, database, etc) with asterisks (i.e. *******).

That way we could see what the lines referred to are.

Is it possible that somewhere in the file (below the red line you recently added or changed) have a reference to VB_SYSTEM_PATH but surrounded with single quotes (')?

As for the CWD error, earlier in this thread someone posted a similar issue, but I did not sede any replies to it, or solutions offered for it. I never saw the error myself, so I cannot really help you figure out exactly what causes this.

I'm starting to think the two errors might actually be related, with the first one somehow preventing the proper vB files to be loaded, which causes the second problem. In addition to the localsettings, could you please also copy/paste the contents of WIKI_PATH/includes/AuthPlugin_vBSSO.php ? That is where all the vB stuff is called. Did you happen to make any changes to that file? (I think I use an older version of the file, so maybe some of the changes made in the last release changed the behaviour).

Strangely enough, I seem to have the same errors on my end.

Could you please elaborate exactly what you did to remove the CWD error?

Thanks for your reply. If I read correctly, the contents of that were meant for vB4, though, right?

[Coleccromos]

Yes, it seems.

I tried this if it worked and it was.


By looking for evidence and I find that when you install mediawiki gives me the following error

• 
  Warning: is_dir() [function.is-dir]: open_basedir restriction in effect. File(/var/lib/php/session) is not within the allowed path(s): (/var/www/vhosts/cromosdefutbol.com/httpdocs:/tmp) in /var/www/vhosts/cromosdefutbol.com/httpdocs/wiki/config/index.php on line 441
• Warning: Your session.save_path value (/var/lib/php/session) appears to be invalid or is not writable. PHP needs to be able to save data to this location for correct session operation.

Any help is appreciated!

ok, finally solved it - in php.ini magic_quotes_gpc was On - set it to off, now it works again...
