Correct. But if you run your own enterprise CA, that's exactly the kind
of thing you can make sure - that nobody else has a certificate from
that CA.
But no, it wouldn't be bad if there was a way to specify exactly which
cert is used. Or at least validate the common name of it agains the
hostname of the server.
