Solution greatly depends on what is the purpose of this: if you just want to be
notified that something is changed then just add to crontab a script which will
check if /etc/passwd and shadow (or `ypcat passwd' if you use NIS instead of
files) are the same as before. If your addmins always use some commands to do
the job you can subsitute the commands with something which will notify you
first and exec the original program. But if you want something to be secure
against real attacker who has root access it will be not easy if possible at
all.
