The claims-based identity model enables an easier way to build applications that are identity-driven, support a variety of audiences and authentication mechanisms and can plug into a heterogeneous infrastructure using standards-based protocols, all without requiring application developers to write a lot of code. Key to the model is the Security Token Service (STS) which issues claims for applications to consume and hosts policies that determine what claims a user will get when accessing a specific application. In this session learn about Microsoft Code Name "Geneva", an STS integrated with Active Directory and Windows CardSpace that provides infrastructure services for federation, claims-aware applications and SOA security.
