On my old blog, before I have lost all the date from the former server, I promised myself an all the readers, who devoted their time to follow my notes, that the time would come, when I write everything I know about putting Federated Security between BizTalk, Workflow Foundation using the AD FS 2.0, StarterSTS to work in SOA architecture. Me and my friend Kacper Oko have already succeeded to do so in our master thesis. Now it’s the time to give back what we’ve taken from the thousands blog post, forum posts which helped us in achieving our goal. I’ll try to describe step by step and from the scratch how to start playing with BizTalk and all other mentioned technolgoies. Already in? See Part 1.
