wcf service SecurityNegotiationException

Question

Hi all,

I am running a Simple Service on my Server with WCF; the service is hosted in WebDev.WebServer.exe (local).

When I call the Service local I get the following exception:

Unhandled Exception: System.ServiceModel.Security.SecurityNegotiationException: Secure channel cannot be opene d because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly s pecified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or implied by the EndpointAddress correctly identifies the remote endpoint. ---> System.ServiceMo del.FaultException: The message with Action 'http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch bet ween the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

Here are my two app.config´s from the client and the server, i made the app.config from the Client with the svcutil-Tool so it should be right:

client

<client>

<



endpoint address="http://localhost:1634/UsuarioContexto.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IUsuarioContexto"





contract="CarWin.ServiceContracts.Interfaces.IUsuarioContexto" name="LOCAL_WSHttpBinding_IUsuarioContexto"> 

<





identity><dns value="localhost" /></identity> 

</





endpoint>

</client>

</security> 

</binding>

any help, please ??

thanks in advanced !!!

Hi there... I feel your pain. WCF is very powerful, but can be a config nightmare. Here are some potential leads:

• Turn on the WCF trace logs, rerun your scenario and then check the logs with SvcTraceViewer.exe
• Figure out how far the messaging gets...
  • i.e. does the client form the request and send it to the server who rejects it (i.e. in the lower WCF layers before your own service code is hit);
  • or does the request get stopped in its tracks before that.. the client never even sending the request
• http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue is a WS-Trust token-related message, so there'll be something going on with authentication
  • the error's implying that there's a config mismatch, but using SvcUtil should have them lined up like you said
• The client binding has the server at "http://localhost:1634/UsuarioContexto.svc"
  • I don't see that port specified in the service config... is the service listening on that port?
  • if you open a browser and aim it at that URL, do you get a default service page?

Hopefully one of these might get you further. Best luck,

Tyler

The problem was in server, I put mode="Message" and works well. thanks.

<security mode="None">  

<transport clientCredentialType="Windows" proxyCredentialType="None" realm="" />  

<message clientCredentialType="Windows" negotiateServiceCredential="true" establishSecurityContext="true" />  

</security>
