Hi Kanta I've just been through a proof of consept implementation of claims authenticated sharepoint and found this guide to be spot on. Take a look at it and see if you might have forgotten something. To me it sounds like the problem might reside in the certificate or at the ADFS side of the configuration. Let us know if you find the error or if you maybe have some more information about your setup. Regards Krister
