Проверка подлинности NTLM в Python

Я пытаюсь выполнить проверку подлинности NTLM в IIS (Windows Server 2003) из Windows 7 с помощью python. Уровень проверки подлинности LAN Manager: отправьте только ответ NTLM.
Клиентская машина и сервер находятся в одном домене.
Контроллер домена (AD) находится на другом сервере (также под управлением Windows Server 2003).

Я получаю 401.1 - Неавторизованный: доступ запрещен из-за неверных учетных данных. Не могли бы вы помочь мне узнать, что не так с этим кодом, и/или показать мне другие возможные направления для решения этой проблемы (используя NTLM или Kerberos)?
