Python-ntlm Authentication

Python-ntlm

Python library that provides NTLM support, including an authentication handler for urllib2.

This library allows you to retrieve content from (usually protected ate) 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)

UsageSimple 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())

Limitations
