Internet Engineering Task Force (IETF) S. Josefsson Request for Comments: 5801 SJD AB Category: Standards Track N. Williams ISSN: 2070-1721 Oracle July 2010 Using Generic Security Service Application Program Interface (GSS-API) Mechanisms in Simple Authentication and Security Layer (SASL): The GS2 Mechanism Family Abstract This document describes how to use a Generic Security Service Application Program Interface (GSS-API) mechanism in the Simple Authentication and Security Layer (SASL) framework. This is done by defining a new SASL mechanism family, called GS2. This mechanism family offers a number of improvements over the previous "SASL/ GSSAPI" mechanism: it is more general, uses fewer messages for the authentication phase in some cases, and supports negotiable use of channel binding. Only GSS-API mechanisms that support channel binding and mutual authentication are supported. Status of This Memo This is an Internet Standards Track document.
