Hi,

could not find it in the draft:

the interoperability with draft-ietf-websec-key-pinning-08 should be
mentioned explicitly to prevent
an attack scenario. (e.g. user has pinned certificate for google.com.
Attacker MITM forces
client to do tls-pwd. Client should not allow this). E.g. once a host is
pinned no other server-side
auth mechanism should be allowed.

regards,

ralf
