Squid + AD - LinuxFr.org

Bonjour,

Je tente de connecter mon serveur SQUID à mon AD 2012, avec kerberos, windbind, tout fonctionne bien, j'ai suivi le tutoriel suivant:
https://access.redhat.com/solutions/3376

tout est ok, tout les tests de ce tutoriel fonctionne.

SAUF QUE,
quand je fais des "systemctl start squid" , systemctl restart squid", ok , aucune erreur.
mais quand je fais "systemctl status squid", la, j'ai de nombreuses erreurs:

# systemctl status squid

squid n'écoute même pas sur le port 3128 quand je fais un netstat… enfin bref.. pas terrible.
