Some people find the concept of claims in connection with Windows Azure Pack hard to understand. To make it easier to understand these concepts, Shri form the WAP teams has created a good whitepaper that goes through the different concepts involved with claims based authentication.
This white paper discusses some concepts, such as claims and federated identity, that may sound new but have been around for a long time. Federation protocols such as WS-Federation and the Security Assertion Markup Language (SAML) have existed for many years as interoperable protocols that are implemented on all major technology platforms.
