A question was raised about this in a recent user group meeting.
When someone steals the server certificate from the real database server
and sets up a MITM with that certificate, this would pass
tls-server-end-point channel binding, because both the MITM and the real
server have the same certificate. But with tls-unique they would have
different channel binding data, so the channel binding would detect this.
Is that not correct?
