Hi, I would like to configure my MOSS 2007 Ent 64 bit sites to use ADFS authentication so that users from my production domain can login to it. The server team has setup a forest trust between the 2 domains and I configured my SharePoint based on this article: Configure Web SSO authentication by using ADFS (Office SharePoint Server) http://technet.microsoft.com/en-us/library/cc262696(office.12).aspx I made web.config changes on both parent site and extended web application but when I try to use people picket in the internal parent site (as said in the above article) I cannot see users from my prod domain. Is there a better article with detailed steps that anybody could share with me or some guidance would be highly appreciated. Regards, Manoj
