  That's a little difficult to do, because the "do proxy" code isn't
tied into the "authenticate" section.  Instead, you could look the
user up in LDAP, and if they're not found, set "Proxy-To-Realm :=
foo", where "foo" is a normal realm.

  Yes.

  Yes.  You can proxy the inner EAP-MSCHAPv2 session as MS-CHAPv2.
Read "eap.conf".
