While WS-Trust provides the primitives for playing the token issuing game, WS-Federation builds on those capabilities and enables to describe the behavior of complex scenarios. Microsoft and IBM recently published a joint whitepaper, titled Understanding WS-Federation, which gives exhaustive descriptions of the specification in action on various notable situations. Namely, the paper really goes in fine details of how WS-Federation handles sing in and resource access management in two fairly realistic scenarios, about enterprise and healtcare (I suspect Roberto is behind the latter :-)). Both the passive and active case are considered. Besides fulfilling its obvious purpose of explaining how WS-Federation work, the paper is a great way of stimulate your thinking about the nuances that emerge in canonical (yet realistic) federation scenarios.
Don announces the paper and give some background here. Suggested reading! :-)
P.S.: I SO need to find a good synonym for "scenario".

Hey Vittorio, thanks for the link to the paper. You are right to suspect Roberto's involvement in the healthcare scenario, he earned his acknowledgement on that one. :-)
Yes, I agree on the need for a synonymn for scenario. I'll let you know if I ever think of a better one than use case.
great work sir ,i hope u continue to provide enlightment to the young developer
