Comment désactiver la sécurité sur le service wcf?

Question

J'ai écrit une application WCF avec la configuration suivante dans le app.config du:

<system.serviceModel> 
    <services> 
     <service name="ProxyService"> 
      <endpoint address="net.pipe://localhost/ProxyService" binding="netNamedPipeBinding" bindingConfiguration="" name="ServiceProxy" contract="IProxyService"/> 
     </service> 
     <service name="PublishSubscribeService"> 
     <endpoint address="net.tcp://localhost/PublishSubscribeService" binding="netTcpBinding" bindingConfiguration="" name="PublishSubscribeServer" contract="IPublishSubscribeService"/> 
     </service> 
    </services> 
</system.serviceModel> 

Je vais avoir un problème avec la demande de rejet de liaison NetTcp (je l'ai inclus l'autre service juste cas ça pourrait avoir un effet mais je ne le pense pas). J'instancier en utilisant le code suivant:

private ServiceHost incomingPipeHost; 
private ServiceHost incomingSubscribeHost; 

incomingPipeHost = new ServiceHost(typeof(ProxyService)); 
incomingPipeHost.Open(); 

incomingSubscribeHost = new ServiceHost(typeof(PublishSubscribeService)); 
incomingSubscribeHost.Open(); 

Tout cela fonctionne très bien lorsque je tente de se connecter au service net.tcp d'un client en cours d'exécution au niveau local, et je l'ai eu ce beau courir sur un site client pour bien plus d'un an. Cependant, je suis maintenant sur un site client différent et lorsque je tente de se connecter à partir d'une machine distante je reçois l'exception suivante:

System.ServiceModel.Security.SecurityNegotiationException: The server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed

J'ai essayé d'ajouter l'extrait suivant au system.serviceModel pour désactiver l'authentification et je reçois toujours la même erreur:

<bindings> 
    <netTcpBinding> 
     <binding name="netTcpBindingConfig" transferMode="Buffered" maxReceivedMessageSize="5242880"> 
      <readerQuotas maxArrayLength="5242880" /> 
      <security mode="None" /> 
     </binding> 
    </netTcpBinding> 
</bindings> 

Qu'est-ce que je fais mal? et que puis-je faire pour essayer de désactiver l'authentification (ce qui n'est pas obligatoire) ou de faire fonctionner l'authentification?

Vous devez dire au EndPoint avec le netTcpBinding d'utiliser la configuration correcte (netTcpBindingConfig):

<service name="PublishSubscribeService"> 
    <endpoint ... bindingConfiguration="netTcpBindingConfig" ... /> 
</service>
