krb524d and KRB524_KRB4_DISABLED

[John Hascall]

As a part of our seemingly endless path to
eliminating KRB4 I was thinking I'd like
to replace or modify krb524d to just log
the request and always return an error
(KRB524_KRB4_DISABLED seems ideal, but as
near as I can tell it only is used in the
client code).  Has anyone gone down this
path before?

Thanks,
John
