A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Point-to-Point Protocol Extensions Working Group 
of the IETF.

	Title		: Microsoft PPP CHAP Extensions, Version 2
	Author(s)	: G. Zorn
	Filename	: draft-ietf-pppext-mschap-v2-02.txt
	Pages		: 17
	Date		: 18-Nov-98
	
The Point-to-Point Protocol (PPP) [1] provides a standard method for
transporting multi-protocol datagrams over point-to-point links.  PPP
defines an extensible Link Control Protocol and a family of Network
Control Protocols (NCPs) for establishing and configuring different
network-layer protocols.
 
This document describes version two of Microsoft's PPP CHAP dialect (MS-
CHAP-V2).  MS-CHAP-V2 is similar to, but incompatible with, MS-CHAP
version one (MS-CHAP-V1, described in [9]).  In particular, certain
protocol fields have been deleted or reused but with different
semantics.  In addition, MS-CHAP-V2 features mutual authentication.
 
The algorithms used in the generation of various MS-CHAP-V2 protocol
fields are described in an appendix.

NOTE:	The mail server at ietf.org can return the document in
	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.

implementation to automatically retrieve the ASCII version of the
