Be able to use with msrest

[Sl1ckR1ck]

Hi, whenever i try to use this authentification with a package that uses msrest, i get a AttributeError: 'HttpNtlmAuth' object has no attribute 'signed_session'.

It would be nice if it would be supported (and possible?)

@Sl1ckR1ck please provide full traceback of the error

Hi, sorry for the delay.

Here is the traceback:

@Sl1ckR1ck can you add code snippet as well

[Sl1ckR1ck]

Here it is.

However this will work best if you have a TFS Server available.

from typing import Sequence
from typing import List

def main(p_Args:Sequence[str]) -> int:
	from azure.devops.connection import Connection
	from msrest.authentication import BasicAuthentication
	from requests_ntlm import HttpNtlmAuth #type: ignore

	p_UserName = "MyUserName" #change this to your TFS user name.
	p_UserPassword = "MyTFSPassword"

	#Change this to another TFS collection.
	TFS_URL = "http://tfsServerTest:8080/tfs/TFSCollection/" 

	credentials=HttpNtlmAuth(p_UserName, p_UserPassword)
	
	connection = Connection(base_url=TFS_URL, creds=credentials)
	
	#This will fail...
	core_client = connection.clients.get_core_client()


if "__main__" == __name__:
	import sys
	sys.dont_write_bytecode = True
	sys.exit(main(sys.argv[1:]))

Hopefully this helps?
