Based on the screenshot above (for facebook), you arent authenticating, as such you have no username or groups.
A rule trace should show you whats going wrong.
thats why I was wondering why it is not authenticating? I have put the usergroup name under the UserGroups that contains "ITG" . what went wrong? is there any specific thing to be place in it ?
Oh ya jon, What about the method to whitelist for certain department ? can you guide me ?
