16.04 Intégration de LTS Active Directory à SSSD - l’authentification ne fonctionne plus

En suivant documentation , j'ai réussi à joindre mes serveurs Ubuntu 16.04 LTS à mon Active Directory exécutant une paire de contrôleurs de domaine Windows 2016. Il fonctionne depuis environ deux semaines mais ne fonctionne plus du tout. J'ai activé le débogage sur sssd pour obtenir une bonne quantité de journalisation, mais je n'arrive pas à identifier le problème.

Pour être plus précis, je peux toujours obtenir des informations sur les utilisateurs et les groupes (avec getent passwd ou getent group) du système, mais l'authentification ne fonctionne pas à partir de SSH et de Sudo.

J'ai joint une bonne quantité de données de débogage au cas où quelqu'un pourrait m'aider à comprendre ce qui ne va pas.

D'accord, cela a pris du temps, mais il y a eu un problème avec le paquet ubuntu pendant un moment, il a été corrigé vers novembre 2017.

https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1684295

Une simple mise à jour de package corrigea le problème, aucune modification ne devait être apportée nulle part.
