Bonjour à tous,
Je suis actuellement en train de tester l’installation d’un serveur CAS afin d’authentifier de manière unique mes utilisateurs Active Directory.
J’ai parcouru un nombre incalculable de sujets, de sites, de forums, mais impossible de trouver le problème.
J’ai téléchargé tous les paquets nécessaires (sun-java6-jdk, sun-java6-fonts, maven2), installé tomcat7, et la version de cas que j’utilise est la 3.5.0 RC1 (cela dit, le problème survient avec toutes les versions que j’ai essayé).
Je déploie le .war qui sert de modèle dans /var/lib/tomcat/webapps, qui crée par la suite le répertoire qui va bien (cas-server-webapp-3.5.0-RC1). Lorsque je ne touche pas au fichier deployerConfigContext.xml, l’application se lance, et je peux avoir accès à la page d’authentification (qui ne sert à rien puisqu’elle n’est pas encore reliée à mon AD).
Je modifie le fichier pom.xml comme indiqué sur ce tuto : http://www.artduweb.com/tutoriels/cas-sso:

| This is the List of CredentialToPrincipalResolvers that identify what Principal is trying to authenticate.

| AuthenticationManagerImpl uses these resolvers for two purposes. First, it uses them to identify the Principal
| attempting to authenticate to CAS /login . In the default configuration, it is the DefaultCredentialsToPrincipalResolver
| that fills this role. If you are using some other kind of credentials than UsernamePasswordCredentials, you will need to replace
| DefaultCredentialsToPrincipalResolver with a CredentialsToPrincipalResolver that supports the credentials you are
| using.
|
| Second, AuthenticationManagerImpl uses these resolvers to identify a service requesting a proxy granting ticket.
| In the default configuration, it is the HttpBasedServiceCredentialsToPrincipalResolver that serves this purpose.

J’ai donc voulu regarder les logs, mais vu que je viens d’installer la version 7, ceux-ci ne sont pas activés par défaut, et je ne vois pas trop comment le faire… (j’ai la tête qui bouillone!) 
J’ai bien sur redémarré le serveur tomcat, essayé les fichiers un à un pour détecter le problème (qui semble bien provenir du deployerConfigContext). Les droits semblent être corrects… (tomcat comme proprio)
Enfin voilà quoi, si vous avez des pistes ou quoi, je suis preneur parce que je retourne la situation dans tous les sens depuis quelques jours et ça n’avance pas énorme (si, j’ai découvert quel fichier posait problème… 
)
Et pour la petite info, je suis sous Debian Squeeze
