We've just posted a new episode of The .NET Show. This one is on "Active Directory Federation Services" (ADFS, formerly known as "Trustbridge"). This is an authorization system that will allow secure cross-domain authorization and access to data, and since it uses the existing Authorization Manager (AzMan for short) methodology, it means that existing applications will easily be able to take advantage of it with little, if any, additional work.
