Hi F23 testers,

I'm running gnome3 desktop, and gdm as desktop manager. It happens very often that after logging out and trying to re-login and after having entered the correct password at the gdm prompt, the login is rejected, so as if trying a wrong password.

Something it helps to kill gdm, but not always.

Perhaps some hint in /var/log/messages:

I filed already a BZ
(https://bugzilla.redhat.com/show_bug.cgi?id=1260487), but getting no answer. The gnome mega update has been applied yesterday, but there is no difference in behaviour between before and after!

If using lightdm instead of GDM, no such problems!

Anybody sees this too or knows some workaraound?

Kind regards
