Puppet : échec de la vérification du certificat

Suite à une erreur, je dois régénérer les certificats du client et du serveur.

Pour autant que je sache, les certificats maîtres sont générés automatiquement.

J'ai donc généré des clés sur le client :

MASTER # puppet cert clean --all
Notice: Revoked certificate with serial 2
Notice: Revoked certificate with serial 6

Avant que vous ne posiez la question, oui, ntp fonctionne et les deux clients ont l'heure correcte.

Quelle est la bonne façon de purger tous les certificats des deux côtés et de tout régénérer correctement ?

J'ai couru :

find /var/lib/puppet -type f -print0 |xargs -0r rm

y

rm -rf /var/lib/puppet/ssl/*

sur le client, mais cela n'a pas aidé.

Il s'agit d'un mélange de Puppet 2 et Puppet 3.
