Description

  • "authentication.mail.cfg" contient les mails de chaque groupe.
  • "authentication.cfg" contient les groupes pour chaque url.
  • "authentication-update" permet l envoi des mails et la mise à jour de l ensemble des serveurs.

Format des fichiers de configuration de l exploitation

authentication.mail.cfg

group;mail[,...][;expiredate]
  • group : nom du groupe
  • mail : mails du groupe séparés par des virgules

authentication.cfg

ApplicationID;URL;group[,...]
  • ApplicationID : nom de l application
  • URL : url complète avec au moins le dernier répertoire suivi d un "/"
  • group[,...] : noms des groupes séparés par des virgules

Pour information

  • ".htpasswd" sert au stockage des mots de passes cryptés. Ce fichier est alimenté en automatique.
  • "<Serveur_applicatif>:/etc/httpd/htpasswd/.<Répertoire uniquement alpha numérique de l appli>.htpasswd" sert au stockage des mots de passes pour chaque appli.
