带有用户名令牌和客户端证书的WCF SOAP调用

Question

I'm trying to get a call to a web service (not sure what the backend is written in) using both a username token (username/pwd) and a client certificate.

Short version : what combination of WCF code/config is needed to generate the SOAP headers below if I have a client cert and a username/password to work with?

Long Version

Below is the service interface as generated by "Add Service Reference" in Visual Studio 2010 (names/URIs changed to protect the innocent):

 [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    [System.ServiceModel.ServiceContractAttribute(Namespace="http://servicenamespacehere", ConfigurationName="Service.Contract.ConfigName.Here")]
    public interface IBackendService {

        // CODEGEN: ...
        [System.ServiceModel.OperationContractAttribute(IsOneWay=true, Action="http://servicenamespacehere#Method1")]
        [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
        void Method1(Method1Params request);

I need the resulting call's SOAP security headers to look as follows:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

   SOAP XML PAYLOAD FOLLOWS...

I was not able to find any comnbination of WCF binding/endpoint settings that would support client message credentials that would include both UserName and Certificate types.

As a result of some searches I found someone who indicated that I needed a custom WCF binding to include both credential types, and they pointed to this MSDN link:

http://msdn.microsoft.com/en-us/library/ms751480(v=vs.100).aspx

But when I follow the code example I get an error:

'The service certificate is not provided for target' 

Now the ClientCredentials object has both a ClientCertificate property (which I successfully load via my client cert's thumbprint), but what is the ServiceCertificate for?

What combination of WCF code/config is needed to generate the SOAP headers above if all I have a client cert and a username/password to work with?

Answer 1

This can only be done with a code binding:

        var b = new CustomBinding();
        var sec = (AsymmetricSecurityBindingElement)SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity10WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10);
        sec.EndpointSupportingTokenParameters.Signed.Add(new UserNameSecurityTokenParameters());
        sec.MessageSecurityVersion =
            MessageSecurityVersion.
                WSSecurity10WSTrust13WSSecureConversation13WSSecurityPolicy12BasicSecurityProfile10;
        sec.IncludeTimestamp = false;
        sec.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.EncryptBeforeSign;

        b.Elements.Add(sec);
        b.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8));
        b.Elements.Add(new HttpsTransportBindingElement());

Answer 2

I am not sure if i understand it correctly but by looking at your error it looks like you are not passing Certificate while creating end point to authenticate the service.

   // Create the service host
   ServiceHost myServiceHost = 
    new ServiceHost(typeof(Calculator), httpUri);
myServiceHost.AddServiceEndpoint(typeof(ICalculator), binding, "");

// Specify a certificate to authenticate the service.
myServiceHost.Credentials.ServiceCertificate.
    SetCertificate(StoreLocation.LocalMachine,
    StoreName.My,
    X509FindType.FindBySubjectName,
    "Contoso.com");
