<p class="MsoNormal">I think this should be deleted, since we’re using an access token to authenticate to the registration endpoint – not a client_secret value. Vladimir pointed out the same thing in a comment on
<a href="https://bitbucket.org/openid/connect/issue/727/registration-brian-campbells-review">
https://bitbucket.org/openid/connect/issue/727/registration-brian-campbells-review</a>.<o:p></o:p></p>

<p class="MsoNormal">2. The Client Update Response at http://openid.bitbucket.org/openid-connect-registration-1_0.html#ClientUpdateResponse currently says:<o:p></o:p></p>
<p><span lang="EN" style="font-family:"Verdana","sans-serif";color:black">The Authorization Server MUST NOT include the Client Secret or Request Access Token in this response.<o:p></o:p></span></p>
<p class="MsoNormal">I’m not sure why it’s forbidden to return the client_secret value upon an update. Is the assumption that the registration server may not change the secret? What if the registration server decides that the updated parameters warrant a
different secret? I think we should remove this restriction and instead say that clients should be prepared to receive and use an updated client_secret, if sent.<o:p></o:p></p>
