linux passowrd re-use problem

[zhicheng wang]

dear all

as Linux does not have a facility to remember the old
passwords for each user, how do i prevent users re-use
their old passwd? is there any software to do this? or
anything like pam can be configured to use some sort
of db to do this?

any suggestions are highly appreciated.
thanks
cheng
