Sorry, I do not understand, what you mean... There is no line with Permissions or account (see Attachement)

AuthPlugin_vBSSO.php seems correct:
define( VB_SYSTEM_PATH, '/home/.lukey/br_noreply/sinnimleben.net/forum' );
$vbsso_forumpath = '/forum';

and also Userlogin.php, which already was set up correct:
$vbsso_forumpath = '/forum';
$vbsso_wikipath = '/wiki';

Thanks for further helps!
