lightdm does not ask for a password when using sssd

[skinny]

1) the release is Quantal (12.10)
2) the package version
lightdm:
  Installed: 1.4.0-0ubuntu2
sssd:
  Installed: 1.9.1-0ubuntu1

3) Lightdm should ask for my password when i goto login.

4) lightdm does not prompt for password for network users

    I have been using SSSD to allow authentication to our AD server.
    My configuration works on all prior versions of ubuntu at least back to 10.04.
    This only happens when using gui from command line I am able to login as the user and it prompts for a password.
    Under user accounts for the network user the option for Automatic Login is set to off
    Command line login works correctly this is only a problem from the gui login page

To recreate this issue:

1.) install 12.10
2.) install packages ntp sssd libnss-sss libpam-sss krb5-user
3.) configure sssd example below
4.) verify that sfu has been setup on AD server and user has been configured with a uid
5.) put your AD cert in the directory supplied
6.) Login as network user from command line to verify sssd is working correctly
7.) reboot and click on network user in lightdm
8.) click login (notice no password prompt)
