The goals of the SAML 2.0 effort include:
(1) addressing issues that have arisen from experience with real-world SAML
1.0 and SAML 1.1 implementations,
(2) expanding the scope of the SAML specification to address features such
as identity
federation, session
context, metadata exchange, authentication services, plus
specify new
SAML profiles that make use of them, such as B2B, A2A, back-office
profiles.
(3) addressing issues that have arisen from the development of other
security specifications that make use of SAML 1.X, such as WS-Security and
XACML
(4) incorporation of the Liberty Alliance ID-FF v1.1 and v1.2
specifications as foundation specifications.
