So the server compares the hostname submitted during the NETLOGON with the
CallingName provided by jCIFS which is something like JCIFS32_129_E5 which
of course doesn't match.

Well jCIFS only submits the CallingName when the session to the domain
controller is established so you would have to open a separate connection
for each user.

Unfortunately I don't think you're going to get this to work. The proper
way to fix this is to implement the NETLOGON procedure in which case the
hostname will be whatever we prefer. This is on The List but it's not
going to happen very soon.
