Microsoft says it won't support SAML 2.0

While I was at SC05, I missed reading a lot of trade press, and while I'm sure that I will never "catch up", going through a few of my most frequently traveled RSS newsfeeds found this.

The bickering between MSFT and the anti-MSFT factions within the WS-* standards is getting very tiresome.  The result in WS-Man / WS-RF battle seems to be a pair of competing standards that provide almost exactly the same functionality.  Now this regarding SAML and WS-Federation.  Sigh.

Schmidt conducted a session today on ADFS (Active Directory Federation Services), Microsoft's software for federated identity, at the company's IT Forum 2005 in Barcelona.

The WS-Federation protocols compete with the SAML (Security Assertion Markup Language) 2.0 specification, which so far has strong footing in the race to create secured identity federation across organizations.

SAML 2.0 protocols are fine for strictly Web single sign-on, Schmidt said. But the WS-Federation protocols are better equipped to deal with a distributed Web-services environment for message reliability, transaction support and security, he said. SAML 2.0 does not have reliable messaging or transaction support, he said. ...
