Hi Phil,

Since I was not in Darmstadt, I really do not know what was discussed
there, but with the compromised developer documentation described in
http://nat.sakimura.org/2016/01/15/idp-mix-up-attack-on-oauth-rfc6749/, all
RFC6749 clients with a naive implementer will be affected. The client does
not need to be talking to multiple IdPs.

Nat
