Turn off the requirement for pre-autentication in the initial AS-REQ
for all principals. The use of pre-authentication makes it more
difficult to do offline password attacks. You might want to turn it
off if you have clients that don't support pre-authentication. Since the
version 4 protocol doesn't support any pre-authentication, serving
version 4 clients is just about the same as not requiring
pre-athentication. The default is to require
pre-authentication. Adding the require-preauth per principal is a more
flexible way of handling this.

.Sh BUGS
If the machine running the KDC has new addresses added to it, the KDC
will have to be restarted to listen to them. The reason it doesn't
just listen to wildcarded (like INADDR_ANY) addresses, is that the
replies has to come from the same address they were sent to, and most
OS:es doesn't pass this information to the application. If your normal
mode of operation require that you add and remove addresses, the best
option is probably to listen to a wildcarded TCP socket, and make sure
your clients use TCP to connect. For instance, this will listen to
IPv4 TCP port 88 only:
