Certificate Requirements for Federation Server Proxies
“It is important to verify that the subject name in the server authentication certificate matches the Federation Service name value that is specified in the AD FS
Management snap-in. To locate this value, open the snap-in, right-click Service, click Edit Federation Service Properties, and then find the value in Federation
Service name text box.”
