I don't know about a *hole*, but it does mean that the security of the
firewall function is dependent of the security of your PDC. I have some
misgivings about this, though at least if they snoop the OWF password
it doesn't mean they'll be able to use it to get through the firewall
since I can't think of any way to trick the firewall into passing that
through unscathed.
