Microsoft IT using AD FS 2.0 case study
This new case study describes how Microsoft IT migrated their federated applications from AD FS 1.0 to AD FS 2.0 and how Microsoft IT uses new AD FS 2.0 features for claims-based identity to simplify and enhance Human Resources Services.
Great story describing how MSIT is using AD FS to federate with external application so that we as Microsoft Employees can access services outside of our network with our common identity.
