if the account is expired on 12/19/2014, (today's date is 12/24/2012), In AD Users and Computer snap-in, the user account's property, Account tab, doesn't have the account disabled checked so indicating not disabled and shows Account expires on 12/19/2014. This data is correct but is mis-leading. Can user still log in using that account? It's not disabled but it's expired. What does that mean?
