J'utilise pour me connecter à mon web service un serveur IIS avec SSL. Le serveur IIS accèpte bien les connexions annonymes.

J'edit afin de donner un peu plus d'infos : le message d'erreur qui correspond à l'exception est :

Citation:

Impossible d’établir une relation de confiance pour le canal sécurisé SSL/TLS avec l’autorité « dev1-03 ».

Je vous remercie pour votre attention. :)
