Hi,
Depending on your trusted-CA package for your SSL client, this
should not verify. There are various ways to confuse SSL clients.
Especially GUI based web-browsers allow to play tricks where
you cant decide whether you are prompted a correct certificate.
Some do not check the signature at all. If in doubt, if there
