samba - Nov 2005 - Password 'must change at next login'

I cannot get this to work.  Either the user's password is valid or it is 
not.  I cannot get anything to tell or offer the user to change 
password.  I can get the expiration date to work now, but when 
expiration time comes and the user tries to login, it simply says login 
denied, password expired.

Ideas?
