There are several motivations for using compound authentication methods
using tunnels, but man-in-the-middle attacks are possible in certain
circumstances when they are used, without cryptographically binding the
methods together. Several protocols currently being proposed within the
IETF are vulnerable to these attacks, including IKE with XAUTH, PIC,
PANA over TLS, EAP TTLS, and PEAP. This document studies the problems
and suggests potential solutions to mitigate them.

MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
