WindowsHttpAuthenticated, suds.transport.TransportError: HTTP Error 401: Unauthorized

[Dineshk77]

I am having the same issue. Below is my code and logs

code:

from suds.client import Client
from suds.transport.https import WindowsHttpAuthenticated
ntlm = WindowsHttpAuthenticated(username="domain\\"+username,password=password)
client = Client(url,transport=ntlm)

error logs:

HTTP Error 401: Unauthorized

    raise HTTPError(req.full_url, code, msg, hdrs, fp)

During handling of the above exception, another exception occurred:

suds.transport.TransportError: HTTP Error 401: Unauthorized

Note:

• same code works for python2.7 (suds==0.4 and python-ntlm==1.1.0)
• Fails in python3.6 (suds-py3==1.3.3.0 and python-ntlm3==1.0.2)
• seems the issue is with https://github.com/trustrachel/python-ntlm3. where the auth_header_value supposed to be a list. The fixes are here in https://github.com/mullender/python-ntlm/blob/master/python30/ntlm/HTTPNtlmAuthHandler.py.

@Dineshk77 Assume the issue is fixed in python-ntlm3 lib and no fix/changes required on suds. If yes let me know I can close this. Thanks!

[Dineshk77]

@cackharot . nope python-ntlm3 is archived and I can't create issues there.

@Dineshk77 Did you find an alternative on windows or work around this?

@cackharot Since python-ntlm3 is not actively maintained anymore, any plans on moving away from this to an alternative?

[Dineshk77]

@Joesafe I just forked the python-ntlm3 repo and replaced the HTTPNtlmAuthHandler.py using https://github.com/mullender/python-ntlm/blob/master/python30/ntlm/HTTPNtlmAuthHandler.py. and downloading my forked repo using pip for my scripts

git+git://github.com/Dineshk77/python-ntlm3@master#egg=python-ntlm3; python_version >= '3.0'

Kind of works but this adds the git dependency
