• dans les credentials utilisés : on met le realm kerberos en majuscules (Exemple : USER1@DOMAIN.LOCAL)
• dans l'inventaire, on modifie la cible en lui attribuant les caractéristiques suivantes : ** comme nom d'hôte, utilisation du FQDN : l'hôte srv1 devient srv1.acme.local

# dig any +short _kerberos._tcp.dc._msdcs.acme.local
dig srv +short _kerberos._tcp.dc._msdcs.acme.local

nslookup
set type=all
_kerberos._tcp.acme.local
_kerberos._tcp.dc._msdcs.acme.local

Ou plus simplement

nslookup acme.local

Dans les variables de l'hôte

ansible_connection: winrm
ansible_winrm_host: srv1.acme.local
ansible_winrm_server_cert_validation: ignore
#ansible_winrm_port: 5986
#ansible_winrm_transport: kerberos 

Pour valider la connexion Kerberos, depuis un nœud d'exécution :

kinit USER1@ACME.LOCAL

Un mot de passe est demandé
