Federated systems need to interoperate across organizational boundaries and connect processes utilizing different technologies, identity storage, security approaches and programming models. Within a federated system, identities and their associated credentials are still stored, owned and managed separately. Each individual member of the federation continues to manage its own identities, but is capable of securely sharing and accepting identities and credentials from other members' sources.

Responding to this need, Microsoft is working with industry leaders to develop a set of specifications for distributed application architecture commonly referred to as Web services.
