Python NTLM login

Question

I am trying to pull information from a url that requires NTLM login.

I originaly received 401 error and after some tweaks have been able to pull the page stating that I have input invalid credentials.

The username and password are correct yet I cannot get past the invalid credentials page.

Lgn2.py:

import urllib2
import HTTPNtlmAuthHandler

login = open('c:/temp/login.txt')
open = login.read()
to = open.split()
user = str(to[0])
password = str(to[1])

url = "http://INSERT URL HERE.com/"
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, user, password)
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)


opener = urllib2.build_opener(auth_NTLM)
urllib2.install_opener(opener)


response = urllib2.urlopen(url)
print(response.read())

I have a username including a \ using the method above I do not get a double backslash in the name when it prints. Should I keep it to where print will have the double backslash in the name as apposed to exactly as the txt file has the username spelled?

The txt file is just a txt document with only: domain\user\name password.

The second backslash in the middle of username would be part of the username.

Any help would be appreciated.

Our company has a proxy and uses NTLM. To connect without having to place credentials in script I used:

import win32com.client

url = 'https://...'

h = win32com.client.Dispatch('WinHTTP.WinHTTPRequest.5.1')
h.SetAutoLogonPolicy(0)
h.Open('GET', url, False)
h.Send()
result = h.responseText
result

Maybe you didn't use a raw string:

Unless an 'r' or 'R' prefix is present, escape sequences in strings are interpreted according to rules similar to those used by Standard C.

>>> 'domain\user'
  File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 6-7: truncated \uXXXX escape
>>> r'domain\user'
'domain\\user'

This works for me (in Python 2, not 3):

from ntlm import HTTPNtlmAuthHandler
import urllib2

user = r'domain\user'
password = "passphrase"
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, "http://projects/", user, password)
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)
opener = urllib2.build_opener(auth_NTLM)
urllib2.install_opener(opener)

url = "http://projects/_vti_bin/owssvr.dll?Cmd=Display&List=etc"
response = urllib2.urlopen(url)
headers = response.info()
print("headers: {}".format(headers))
body = response.read()
print("response: " + body)
