There is not an easy way. UNIX passwords are one-way encrypted.
The only way to de-crypt is with a dictionary, and even then
you won't get all of them (or most of them, or some of them).

For once they are not. Have to mark that one (guess there is a
first for everything).

If you are interested in RadiusNT, it has an option to replace
passwords in ODBC mode. Its very similar to your sniffer idea,
but does it automatically. The users come in authing with PAP
(chap doesn't work here) and RadiusNT has the clear text password.
It auths that against your unix passwd file and can verify that
it is indeed the password. Then it stores that password over
the "UNIX" password. We can do that with WINNT passwords as
well. Then if you use a mail server like NTMail that can
auth from an Emerald DB, you are set.
