Kim Cameron has posted a really good video here explaining how user-centric identity and federation can work together. His blog and associated demonstration is shown using Microsoft CardSpace and Ping Federate from Ping Identity.
I have worked with Ping Identity for some time and was happy with the product and how it, and federation works generally. However, like Paul Squires here, I was struggling to see how it fitted within a user-centric architecture. Whilst I saw the two as complimentary, I didn’t see the link.
This video has clarified this for me and shown that there is a clear interaction between the two.
As usual Kim, thanks for a great demo! If you haven’t seem the demo yet, you HAVE to view it.
