Ignore FSDriverRequired when attempting to get DFS information for a BadNetworkName handler

Hi, the following error occurred: Failed to authenticate with server: SpnegoError (1): SpnegoError (16): Operation not supported or available, Context: Retrieving NTLM store without NTLM_USER_FILE set to a filepath, Context: Unable to negotiate common mechanism

My code:

from smbclient import listdir, mkdir, register_session, rmdir, scandir, open_file
register_session(server=host, username=username, password=password)
with open_file(r"\\" + os.environ['fsxDns'] + "\\" + eKey, mode="w") as fd:
            fd.write(eObjBody)

Traceback:

Traceback (most recent call last):
File "/opt/python/smbprotocol/session.py", line 278, in connect
	out_token = context.step(in_token)
File "/opt/python/spnego/_negotiate.py", line 124, in step
	mech_token_in, mech_list_mic, is_spnego = self._step_spnego_input(in_token=in_token)
File "/opt/python/spnego/_negotiate.py", line 171, in _step_spnego_input
	mech_list = self._rebuild_context_list(mech_types=in_token.mech_types)
File "/opt/python/spnego/_negotiate.py", line 416, in _rebuild_context_list
	raise BadMechanismError(context_msg="Unable to negotiate common mechanism", base_error=last_err)

During handling of the above exception, another exception occurred:

Any help will be appericated. Thank you 😄

I’m going to keep this open as a reminder to ignore FSDriverRequired in that particular bit of code. It would have hopefully made the problem clearer.

ahhhh got it, I missed to add the share name in that string. Many thanks!
