In Ubuntu 12.04, when logging in using the unity greeter in lightdm (1.1.9-0ubuntu1) with a user using Kerberos with an expired password, the login screen doesn't give the user the appropriate feedback to set their new password. The text console works correctly. The previous LTS used GDM, which behaved correctly.

The normal prompting for this is:
Username: cmo-test
Password: ****
Password expired. You must change it now.
Enter new password: ****
Enter it again: ****

Instead, in lightdm, it is:
Username: cmo-test
Password: ****
Enter it again: ****

The "Password expired" message is never shown, and "Enter it again" is shown in the box instead of "Enter new password". If you use lighdm-gtk-greeter, you get the "password expired" message printed under the box, but still have the same prompting, never asking for the new password.
