I have a AD FS 2.0 server (Server 2012) in my forest root domain. My user domain is a child domain within that forest. I am unable to find any documentation that tells me if I need to do any further configuration to have it authenticate users from the child domain or if that should just magically happen because of the Parent Child trust relationship.
Upon rebuilding the server again and making sure that the server name and the pool name were diffrent so I could create the proper SPN entries, I am now unable to access my server using any of the AD FS urls'. It will prompt me for my credentials 3 times and then tell me I am not Authorized. I have been searching on the web but have been unable to find the solutionsI have made DNS changes, added http SPN entries. Changed the Authentication settings on IIS... I am stuck. Any help would be great.
