<span style="font-family:"Verdana","sans-serif"">The UserInfo Endpoint is a Protected Resource that returns Claims about the authenticated End-User. Claims are represented by a JSON object that contains a collection of name and value pairs for the Claims.<o:p></o:p></span></p>

<p class="MsoNormal">Does Userinfo Endpoint only provide data for authenticated End-user? Or is it a generic protected resource that returns whatever have been authorized at the authorization server? In another word, is the value of sub in the ID Token and
the Userinfo response for the access token whose hash is in the ID Token the same? <o:p></o:p></p>
