OK, I finally have Kerberos set up. I can confirm this works in 12.10 but not 12.04. Will work on a fix for 12.04.

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.
