Title:
  lightdm does not ask for a new password with pam_winbind or pam_krb5
  authentications when the password is expired

Status in lightdm package in Ubuntu:
  Confirmed

Bug description:
  I'm using an up-to-date oneiric workstation joined through samba and
  winbind to an AD domain controlled by a Windows server.

  When the password of a domain user is expired and when pam_winbind is
  used as first authentication, lightdm does not ask for a new password
  and does not allow to login, displaying the message "Invalid password,
  please try again".

  Instead, when pam_krb5 is used as first authentication, lightdm asks
  two times for a password ("Enter it again:") and then allows to login
  even if the password is expired.

  When using a text console to login, the password changing dialog is
  immediately presented (as it happens in natty with gdm).
