Kerberos behind load balancer?

Actually, a load balancer simplifies client deployment in our case (we
can't utilize DNS load balancing on our campus). We can, with a load
balancer, have all of the KDC's share one hostname. Our kadmin server
can also share that hostname.

 kerberos:88 -> points to our KDC's
 kerberos:749 -> point to our admin server

Further, we can bring systems up/down or add/remove new systems without
requiring modifications to the client configurations.

I've actually got this working, except that I needed to associate the
kerberos hostname with a non-arping loopback device, which required a
minor code hack.
