I’ve started to take a look at the Azure AppFabric Access Control Service (ACS), and have started an ACS sectionon Cloud Casts. The first webcast looks at using social identity providers to provide authentication for websites. I’m going to focus on ACS for a bit and wait for the AppFabric messaging capabilities to be released before returning to them and looking in more detail. I have a few webcasts on AppFabric messaging here.
