  Your question doesn't make sense.  Pam and Unix /etc/passwd are both
systems that store "known good" passwords.  MSCHAPv2 is an
authentication protocol where a user tries to authenticate based on an
unknown password.

  No the crypt'd passwords stored in /etc/passwd are 100% incompatible
with PEAP.  You can:

  a) store clear-text passwords
  b) use EAP-TTLS with tunneled PAP.

  You don't really have many other choices.
