<p>Hi Denniss,</p>
<p>may interested parties at remote locations contribute as well?</p>
best regards,<br>
Torsten.<br>

PS: where had the OIDF workshop been announced? I don't remember a

The consensus was that we should publish a formal-ish (board
reviewed) blog post / bulletin with implementation advice on how
to mitigate Mix-up and Cut-and-Paste in Connect.

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>

Why don`t we bring this discussion to the
OAuth WG? It`s nearly the same group of people
as on this list.<br>
