This document defines an extension to the Network News Transfer
Protocol (NNTP) that allows a client to indicate an authentication
mechanism to the server, to perform an authentication protocol
exchange, and optionally to negotiate a security layer for subsequent
protocol interactions during the remainder of an NNTP session.

This document updates and formalizes the AUTHINFO USER/PASS
authentication method specified in RFC 2980 and deprecates the
AUTHINFO SIMPLE and AUTHINFO GENERIC authentication methods.
Additionally, this document defines a profile of the Simple
Authentication and Security Layer (SASL) for NNTP.  [STANDARDS TRACK]
