Hey,
I have this problem too.
I found out that when I have this problem, in auth.log stands this:
lightdm: pam_unix(lightdm:session): session opened for user lightdm by
(uid=0)
lightdm: pam_ck_connector(lightdm:session): nox11 mode, ignoring PAM_TTY :0
lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup
nopasswdlogin" not met by user "johannes"
dbus[1054]: [system] Rejected send message, 2 matched rules;
type="method_call", sender=":1.50" (uid=104 pid=3135
comm="/usr/lib/indicator-datetime/indicator-datetime-ser")
interface="org.freedesktop.DBus.Properties" member="GetAll" error
name="(unset)" requested_reply="0" destination=":1.15" (uid=0 pid=1527
comm="/usr/sbin/console-kit-daemon --no-daemon ")
When I can log in normally, auth.log says:
lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup
nopasswdlogin" not met by user "johannes"
lightdm: pam_unix(lightdm:session): session closed for user lightdm
lightdm: pam_unix(lightdm:session): session opened for user johannes by

Don't know if this helps.

Title:
unable to log in - hangs on 'logging in' msg
Status in Light Display Manager:
New
Status in “lightdm” package in Ubuntu:
Confirmed
Bug description:
On my laptop I upgraded from 11.10 to 12.04, 3 or 4 weeks ago.
Recently I had trouble logging in - I'd type in my password but it
would hang on the 'logging in...' message you get after pressing
enter. After rebooting a few times I was able to log in.
Now, rebooting isn't helping, I'm unable to log in at all. I stay at
the 'logging in...' message until I shut down.
