I just finished reading The Truth About Federated Identity Management by Sarah D. Scalet at CSO. It's a good read, focussing on the importance of the business case in deploying federated identity and the fact that 80% of the work in any federation deployment is on the business side. The technology, by comparison, pretty much "just works". Make sure you hit the sidebar too: Thinking of Doing Federated Identity Management?.
