Alas, as of 18:00 GMT, it is still broken.

I can confirm that restarting Samba after the log in allows access to
the server again.

In case the problem has been changed by your changes, below is the
chunk of log.smb that relates to an authentication failure.

Two differenes I have been able to see are the call_id in
prs_set_packtype, and the data in ncalrpc_l_send_prs (don't know if
this one should vary).

Paul.
