You need to bind to all the interface addresses in order to assure
that KDC replies come from the address they were sent to..

At least some kerberos implementations verify that responses are
received with a source address equal to the address of the KDC.

If the KDC is multi-homed, binding to all of the machine's addresses
individual is the only vaguely portable way to know which address a
packet was sent to..
