Currently trying to copy a working farm that uses ADFS to authenticate users. My SharePoint farm authenticates users perfectly using NTLM. I followed the steps provided by Microsoft to set up an ADFS server and attempted to copy the settings from the working farm. When I set the authentication mode to the Trusted Identity Provider, a user who tries to reach SharePoint is routed to the ADFS server, where they receive the 403 error.
Enabled detail reporting. The specific error I am getting is: HTTP Error 403.7 - Forbidden The page you are attempting to access requires your browser to have a Secure Sockets Layer (SSL) client certificate that the Web server recognizes.
