OK, I use kerberos in my script, so I tried your line on my client and
fails but not in the same way:

SPNEGO login failed: The attempted logon is invalid. This is either due to a bad username or authentication information.
ERROR(runtime): uncaught exception - (3221225581, 'The attempted logon is invalid. This is either due to a bad username or authentication information.')

To get it to work, I replaced '--server=rpidc1' with
'--server=rpidc1.samdom.example.com', perhaps using the servers FQDN
will work for you.
