+1 Gidget. There is another aspect to mind as well. A warning from the admins to change passwords means that an attacker may have got access to password hashes so that account abuse is possible. Publicly declaring not to update the own passwd is an invitation for such a possible attacker. Those persons in particular should think twice about letting their password unchanged.
