SAML 2.0 is the culmination of work stemming from OASIS, the Liberty Alliance and the Shibboleth Project. These standards bodies combined their work in enhancing SAML 1.0 to create SAML 2.0. In March 2005, SAML 2.0 was ratified as an official OASIS industry standard and is now backed by vendors and organizations around the world as the "de-facto" industry standard for deploying and managing open identity-based applications. SAML 2.0 represents a significant step toward the convergence of identity standards and moving forward, all enhancements to Liberty Federation will be based on SAML 2.0.
The Liberty Alliance added support for SAML 2.0 to Liberty Web services in 2005 and at that time incorporated SAML 2.0 testing into its Liberty Interoperable™ conformance program.
Liberty Federation, which consists of ID-FF 1.1, 1.2 and SAML 2.0 specifications, allows consumers and users of Internet-based services and e-commerce applications to authenticate and sign on to a network or domain once from any device and then visit or take part in services from multiple Web sites. This federated approach does not require the user to re-authenticate and can support privacy controls established by the user.
