Accounts that have "pw_change" set, are supposed to change their passwords
by the date specified in "pw_change".  If they have not changed their passwords
by that date, currently they get "LOCKED OUT" of the system.  This is not the
correct behavior, the user should be prompt (forced?) to change their password
at this time.  If the behavior of "pw_change" was meant to be a LOCKOUT,
then you should use "pw_expire".

Solution:
     Instead of locking out the user, prompt them to change their password.
