Python library that provides NTLM support, including an authentication handler for urllib2.
This library allows you to retrieve content from (usually corporate) servers protected with windows authentication (NTLM) using the python urllib2.
Python 3 Support
There is work going on to port the library to python 3, you can find it in the python30 directory. (at this time it seems to work as good as the python 2 library)
Usage
Simple example
import urllib2
from ntlm import HTTPNtlmAuthHandler
user = 'DOMAIN\User'
password = "Password"
url = "http://ntlmprotectedserver/securedfile.html"
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, user, password)
# create the NTLM authentication handler
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)
# create and install the opener
opener = urllib2.build_opener(auth_NTLM)
urllib2.install_opener(opener)
# retrieve the result
response = urllib2.urlopen(url)
print(response.read())
Extended Example
import urllib2
from urlparse import urlparse, urlunparse
from ntlm import HTTPNtlmAuthHandler
user = 'DOMAIN\User'
password = "Password"
url = "http://ntlmprotectedserver/securedfile.html"
# determine a base_uri for which the username and password can be used
parsed_url = urlparse(self.href)
base_uri = urlunparse((parsed_url[0],parsed_url[1],"","","",""))
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, base_uri, user, password)
# create the NTLM authentication handler
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)
# other authentication handlers
auth_basic = urllib2.HTTPBasicAuthHandler(passman)
auth_digest = urllib2.HTTPDigestAuthHandler(passman)
# disable proxies (if you want to stay within the corporate network)
proxy_handler = urllib2.ProxyHandler({})
# create and install the opener
opener = urllib2.build_opener(proxy_handler, auth_NTLM, auth_digest, auth_basic)
urllib2.install_opener(opener)
# retrieve the result
response = urllib2.urlopen(url)
print(response.read())
