But they will only use DNS SRV records if the krb5.conf file permits
it and there is no domain/realm mapping entry in the krb5.conf file
for the resulting hostname or domain.

A good solution for this would be to provide a new RPC that can be sent
to any AFS service that requires authentication that would return a
list of local authentication domains:

 * Kerberos 4: KERBEROS.REALM

 * Kerberos 5: KERBEROS.REALM

 * Kerberos 5: ANOTHER.REALM

etc.

Then aklog could obtain the list of AFSDB records and query the servers
directly.
