Abstract
This document describes the authentication option to the telnet [1]
protocol as a generic method for negotiating an authentication type
and mode including whether encryption should be used and if
credentials should be forwarded. While this document summarizes
currently utilized commands and types it does not define a specific
authentication type. Separate documents are to be published defining
each authentication type.
This document updates a previous specification of the telnet
authentication option, RFC 1416 [2], so that it can be used to
securely enable the telnet encryption option [3].
