Comment 3 for bug 653132

What one is supposed to do is to enter user name and password of a user who is in the lpadmin group. I have tried that running system-config-printer on the desktop of a test user (not in lpadmin) and entering the credentials of the first user installed (is in lpadmin).

Unfortunately, and this is a real bug, either in system-config-printer or in some authentication infrastructure in Ubuntu, the credentials do not get accepted and s-c-p falls into an unbreakable infinite loop of the credentials dialog and the dialog telling that the credentials are not correct.

Tim, can you look into that?
