403 - l'Accès est refusé après l'authentification

Salutations!

Quand j'essaye de l'authentification à l'encontre de ma base de données existante je suis authentifié mais j'obtiens la page 403. Si j'ai juste essayé un mauvais mot de passe que j'ai obtenu un faux diplômes message tant attendu.
J'ai essayé d'authentification par exemple d'application inclus avec SpringSecurity et qui fonctionnait bien.

security-context.xml:

Permettra d'apprécier l'aide 🙂
Merci à l'avance!
