Changing a User's Password to One Already in Use

CAUSE

The Password Uniqueness feature allows administrators to force users to change passwords regularly and not to use the same password over and over. It is up to the administrator to decide how to use Password Uniqueness and when to override it and reset a user's password.

A user's password history is not remembered when Password Uniqueness is set. By design, password history does not apply when an administrator is setting a user's password--only when users are changing their own passwords.

(Under LAN Manager 2.x, you can do the same thing by changing the Password Uniqueness setting to zero, resetting the user's password, then returning Password Uniqueness to its previous value.)
