This document updates RFC 4120, as it specifies an extension in the
Kerberos protocol. It defines a new authorization data type,
AD-AUTHENTICATION-INDICATOR. The purpose of introducing this data
type is to include an indicator of the strength of a client's
authentication in service tickets so that application services can
use it as an input into policy decisions.
This document is a product of the Common Authentication Technology Next Generation Working Group of the IETF.
This is now a Proposed Standard.
