r8250: More PAC work. We now sucessfully verify the KDC signature from my DC
(I have included the krbtgt key from my test network).
It turns out the krbtgt signature is over the 16 (or whatever,
enc-type dependent) bytes of the signature, not the entire structure.
Also do not even try to use Kerberos or GSSAPI on an IP address, it
will only fail.
