Identity management for cloud deployed applications can be a challenge. Often users will want to leverage an existing social network or corporate identity. Now we have to worry about dealing with multiple APIs, any updates to those APIs, or the addition of new identity providers. Windows Azure Access Control Services offers a better way! ACS allows for federated user authentication via popular social networks and Active Directory. In this session we’ll provide a crash course in claims as they relate to identity management. We’ll discuss why claims are important and how to add additional claims beyond what is provided by the identity providers. We'll also take a look at Windows Azure Active Directory and see how to manage corporate identities in the cloud.
