Starting with the PDC release, Microsoft’s identity framework is now code-named “Geneva Framework”. Based on that framework, there is also a product called “Geneva Server” that brings the ADFS 1.x type of functionality (and more) to the web services/WS-Trust/CardSpace world. Furthermore there is also a release called “Geneva CardSpace” which seems to be CardSpace v.Next.
You can download all the new bits here.
I already had the chance to test-drive some of the new bits and made some interesting observations – stay tuned ;)
