"CHAP requires that both the client and server know the plaintext of the 
secret."

/etc/(master.)passwd uses a one-way password hash.  The server cannot 
know the secret.  You'll need a separate database.

It might be possible to use a pam module to use either CHAP directly, or 
reference whatever second database you have, so you still only have one 
set of passwords.  I have no specific suggestions here though.
