Bug description:
  Kerberos accounts on Ubuntu 12.04.1 can't force password changes via 

  [Test Case]
  1. Set up a Kerberos server and client machine (see 
  2. Log into unity-greeter on client machine
  Expected result:
  Unity Greeter shows appropriate prompts to change password and can log in 
once password changed/
  Observed result:
  Some prompts skipped, password not changed and unable to log in.

  [Regression Potential]
  Potential of breaking other authentication. This has been tested with the 
lightdm regression tests.

  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
