1.3 Overview

This document specifies the Query String Response Transfer Protocol and the SAML 1.1 Assertion Extension. These extensions are based on the federated sign-on protocol described in [MS-MWBF]. The extensions specified in this document broaden the applicability of the protocol to simpler web browser requestors and a wider range of protected applications. The extensions in this specification do not change the services of authentication, identity federation, or single sign-on provided by [MS-MWBF].
