Implementing WIF ActAs Scenario: The identity check failed for the outgoing message

Question

So I'm trying to consume a WCF service from a website and pass the IClaimsIdentity the site got from an STS through to the service.

When I try to invoke a service method through an ActAs channel, I get the following error on the client (looking at trace logs, it never gets to the service, and the STS sends through all tokens correctly):

The identity check failed for the outgoing message. The expected identity is 'identity(http://schemas.xmlsoap.org/ws/2005/05/identity/right/possessproperty: http://schemas.xmlsoap.org/ws/2005/05/identity/claims/thumbprint)' for the 'http://localhost/MyWCFHost/MyService.svc' target endpoint.

I've got a custom IssuedTokenForCertificate binding and all the certificates are OK as far as I can see, it should work, but no dice. I'd appreciate another pair of eyes looking over my config and helping:

Answer 1

Sorted out my problem by changing the binding in the service config to ws2007FederationHttpBinding instead of CustomBinding and update my client service reference.

<bindings>
  <ws2007FederationHttpBinding>
    <binding name="serviceBinding" receiveTimeout="05:00:00" sendTimeout="05:00:00">
      <security mode="Message">
        <message>
          <issuerMetadata address="http://localhost/MyCompany.SecurityTokenService/ActAsIssuer.svc/mex"/>
        </message>
      </security>
    </binding>
  </ws2007FederationHttpBinding>
</bindings>

Then because I'm using self-signed certificates, I had to change the certificateValidationMode using the following endpoint behaviour in the client config:

<behaviors>
  <endpointBehaviors>
    <behavior name="MyServiceBehavior" >
      <clientCredentials>
        <serviceCertificate>
          <authentication certificateValidationMode="PeerOrChainTrust"/>
        </serviceCertificate>
      </clientCredentials>
    </behavior>
  </endpointBehaviors>
</behaviors>

And finally I just had to ensure my certificate was in the Trusted People store and finally I get the correct IClaimsIdentity when invoking the service :)

Hope this helps someone out there, because it drove me nuts for a while...
