<p dir="ltr">I think there are two discussions. </p>
<p dir="ltr">One is what the OAuth WG should do and that should be on the OAuth list.</p>
<p dir="ltr">There is a separate discussion about what Connect should recommend untill OAuth addresses the issue. </p>
<p dir="ltr">I think the latter was how this thread started. </p>
<p dir="ltr">We not be should not wait for OAuth to recommend something before we explain the existing mitigations in Connect.</p>
<p dir="ltr">The touchier topic is should we add anything new before OAuth decides. <br>

To Brian's point about the AS not identifying itself in the response, that was the recommended change from the Darmstadt meeting. I am however hesitant to take that up as a Connect only fix even though it would work just fine for Connect. <br>
