Univention Bugzilla – Bug 34442
No poweroff/reboot buttons visible in lightdm unity-greeter

The current lightdm version contains a bug concerning the greeters poweroff/reboot buttons. They are not visible if systemd's logind is running. Lightdm then only creates a logind connection, but no ConsoleKit connection. With that, the internal functions to determine if the user may reboot the system fail silently, leaving the shutdown dialog empty. The bug is fixed in Debian but not upstream. For UCC 2 the Debian patch will be applied and lightdm rebuild in our environment.
The initial bug reason is not correct. The problem is caused by pam_systemd missing from the common-session file. I added session optional pam_systemd.so to common-session in r49009 univention-ucc-pam 2.0.0-2.38.201404031144 internal bug while updating to 14.04, no changelog entry
The power down and reboot buttons are now properly displayed and working fine, boit the reboot and the shutdown worked well.
UCC 2.0 has been released: http://docs.univention.de/release-notes-ucc-2.0.html If this error occurs again, please use "Clone This Bug".
