Microsoft has published the third in a series of step-by-step guides on configuring AD FS 2.0 to interoperate with partner products. This guide describes how to configure AD FS 2.0 and Shibboleth to federate using the SAML 2.0 protocol. There is also an appendix on federating with the InCommon Federation. The guide is available in Word format and HTML. Thanks again to author Dave Martinez.
