Subject: SAML extensions for authorization from Open Grid Services Architecture
A draft set of extensions to SAML for use with authorization has been submitted to the Global Grid Forum OGSA Security Working Group. Some of these proposed extensions could be replaced by the XACML recommendation to the SSTC for use of XACML Request/Response in SAML 2.0, but the XACML recommendation does not satisfy all their requirements. We might want to revise or augment our recommendation in order to incorporate more of the Grid requirements. It is not clear whether GGF would actually submit their extensions to the SSTC, but XACML might be able to advise the SSTC on how best to meet these new requirements without adding multiple, overlapping extensions. The spec isn't too long, and the actual description of the extensions is only a portion of the spec, so review is not a major task. See http://www.globus.org/ogsa/security, and look at the bottom of the page under "Other documents" for "Use of SAML for OGSA Authorization". Anne -- Anne H.
