In a kerberos authentication, the service does not communicate with the
KDC. The service
already knows its private key necessary to decrypt the blob given by the
KDC to the client
for delivery to the service.
Even the client will not communicate with the KDC if it already has a
valid service ticket for
the service it is attempting to authenticate to.
