A RADIUS Attribute, Binding, Profiles, Name Identifier Format, and
Confirmation Methods for the Security Assertion Markup Language (SAML)
Abstract
This document describes the use of the Security Assertion Markup
Language (SAML) with RADIUS in the context of the Application
Bridging for Federated Access Beyond web (ABFAB) architecture. It
defines two RADIUS attributes, a SAML binding, a SAML name identifier
format, two SAML profiles, and two SAML confirmation methods. The
RADIUS attributes permit encapsulation of SAML Assertions and
protocol messages within RADIUS, allowing SAML entities to
communicate using the binding. The two profiles describe the
application of this binding for ABFAB authentication and assertion
Query/Request, enabling a Relying Party to request authentication of,
or assertions for, users or machines (clients). These clients may be
named using a Network Access Identifier (NAI) name identifier format.
Finally, the subject confirmation methods allow requests and queries
to be issued for a previously authenticated user or machine without
needing to explicitly identify them as the subject. The use of the
artifacts defined in this document is not exclusive to ABFAB. They
can be applied in any Authentication, Authorization, and Accounting
(AAA) scenario, such as network access control.
