Adding this feature would open up the pwdModify exop as a mechanism for
password guessing attacks. In fact, in the next draft of the ppolicy spec I
was intending to explicitly forbid this type of usage, to prevent such attacks.
The ppolicy spec provides for grace logins after a password is expired, to
give users a few last opportunities to change their password. If they don't
take advantage of those grace logins, then they are out of luck and must get
help from a password administrator.
I'm going to reject this ITS.
