    abstract =  {This document specifies a RADIUS attribute, a binding and two profiles for the Security Assertion Mark-up Language (SAML). The attribute provides RADIUS encapsulation of SAML protocol messages, and the binding describes the use of this attribute, and the SAML protocol messages within, with RADIUS transport. The two profiles describe the application of this binding for ABFAB authentication and assertion query/request respectively. The SAML RADIUS attribute and binding are defined generically to permit application in other scenarios, such as network access.},
