Ok I have got this mod working successfully for vBulletin 3.8.6 and MediaWiki 1.17 with PHP 5.3. In fact, the vB version shouldn't really matter at all.
Ok first of all wrap the CMD constant in an if statement, as outline in
post #215.
Second of all open up the AuthPlugin_vBSSO.php file in the includes directory of Mediawiki and search for the line:
Code:
function vBSSOAutoAuth(&$user) {
Simply delete the "&" from this line and the plugin will work fine with PHP 5.3 and above
