Microsoft meets SAML2
By Bert Van Beeck on Nov 14, 2008
In the world of federation, there are a few standards available to
allow human2application single sign-on. The open standards include SAML2 and ID-FF (now part of SAML2), and Microsoft's WS-Federation.
As SAML2 and WS-Federation are mutually incompatible, it has been a challenge to connect WS-Federation platforms with those supporting SAML2.
Fortunately, Microsoft recently announced last few weeks that their new Server platform "Geneva" will be supporting SAML2 as a federation platform. This basically means that Geneva servers can start playing a role as IDP or SP in a federated environment. Combinations of .NET platform federating with an OpenSSO via SAML2 will become easy, the vice versa should also be possible.
Good Job Microsoft on embracing the Open Standard SAML2 !!! I'm looking forward to future circles of trust that will be created as a result of this.
