Not <Shift+F5> - <Ctrl+F5> (The control key)
Also, I'm not quite sure why but I'm out of time to troubleshoot it with you for now. In the meantime, you can make this modification to Userlogin.php to make it work until I can figure it out:
Find this line:
PHP Code:
$redirlink = '?url=' . $vbsso_wikipath . '/index.php/' . $returnNS;
Replace it with this:
PHP Code:
$redirlink = '?url=/wiki/index.php/' . $returnNS;
Please note, this only applies to BRotondi's case; I will update the code later tonight so that this works for all installations.
After you've made this change, please clear your browser's cache (Usually in privacy settings) because MediaWiki likes to cache pages until the end of time, heh...
