Description of problem:
If an account has the last password change set to the epoch to force a password change, *and* the accounf's expiration date has passed, 
changing the password allows the user to log in.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. chage <user> -d 0 -E <yesterday's date>
2. login as <user>
3. change password as instructed
	

Actual Results:  Shell prompt (as user).

Expected Results:  Your account has expired.  Please contact your system administrator.
Password incorrect.

Additional info:

I think an expired account should take precedence over a forced password change.  There's no point in allowing someone to change their 
password if they're not supposed to be able to log in.
