Authentification NTLM en Python

j'essaie d'implémenter L'authentification NTLM sur IIS (Windows Server 2003) depuis Windows 7 avec python. Niveau D'authentification LAN Manager: envoyer la réponse NTLM seulement.

Ordinateur Client et le serveur sont dans le même domaine.

Domain controller (AD) est sur un autre serveur (Windows Server 2003 est également en cours d'exécution).

je reçois 401.1-non autorisé: L'accès est refusé en raison de justificatifs d'identité invalides. Pourriez-vous svp m'aider à trouver quel est le problème avec ce code et/ou me montrer les autres directions possibles pour résoudre ce problème (en utilisant NTLM ou Kerberos)?

j'ai trouvé ce qui n'allait pas. Je devrais garder la connexion vivante. C'est la marchandise! Maintenant ce problème est résolu.
