Asked: as a developer, can I access the ADAM repository as well to facilitate SSO perhaps?
Answered: Active Directory Application Mode (ADAM): ADAM, an independent mode of Active Directory without infrastructure features, provides directory services for applications. Operating as a stand-alone data store or interacting with an Active Directory domain controller, ADAM's flexibility enables administrators to tailor their directory services infrastructure to varying degrees of local control/autonomy or shared services. ADAM provides a data store and services for accessing that data store, uses standard application programming interfaces (APIs) for accessing application data, and works with ADFS to provide a user store for extranet application authentication. http://www.microsoft.com/WindowsServer2003/R2/Identity_Management/default.mspx
