Comment 24 for bug 431147

michael-dance - your issue is different to the issue described by neal-landry. Your issue seems to be because you're trying to authenticate from a session which is not on the active console, and the behaviour there is expected.

The output of ck-list-sessions looks wrong, as your session seems to have been added to a dynamic seat, which would break things in the way you describe. Could you please edit the "Exec=" line in /usr/share/dbus-1/system-services/org.freedesktop.ConsoleKit.service to read "/usr/sbin/console-kit-daemon --debug", then restart, log in and attach your /var/log/syslog?
