How would a developer use WIF, ADFS V2, and Windows Live ID with ACS?
ACS, WIF, and AD FS v2 can be used together to develop web services that combine the security and capability of Active Directory with the flexibility and control of custom access control rules, within a simple, closely integrated developer experience. Access Control allows developers to manage access to RESTful web services using a cloud-based service instead of writing complex authorization code into their application. This means developers can more easily build REST services that require federation with multiple AD FS instances and/or need fine-grained authorization rules. Active Directory Federation Services 2.0 can federate with ACS, which accepts tokens from AD FS 2.0 and repackages them with new claims. At v1, there will be community samples that demonstrate how to use WIF and Active ADFS 2.0 with Access Control. WIF will be used to acquire a SAML token from ADFS 2.0and to extract the claims from an ACS-issued token. Note that extracting claims from an Access Control-issued token
