Problème avec l'authentification d'un service Wcf

Bonjour tout le monde,

J'ai développé un service Wcf tout simple de test.

Cet exemple marche bien seul mais quand je veux lui ajouter l'authentification, il plante.

J'ai configuré la trace de diagnostics pour le service Wcf, mais les messages d'erreur que j'obtiens avec l'outil de trace sont :

"Echec lors de l'ouverture de System.ServiceModel.ServiceHost"
"System.ServiceModel.ServiceHost a généré des erreurs"
"Une erreur System.ServiceModel.ServiceHost est survenue.

Je me suis basé sur un exemple simple que j'ai trouvé sur le net et je pense que je l'ai bien reproduis

Voici le Web.Config du service Wcf :

                serviceProxy.ClientCredentials.UserName.Password = "test123";
 
                string sReturned = serviceProxy.GetData(14);

Ai-je oublié quelque chose ?

Merci beaucoup par avance.
