Question

We are attempting to use the ACS sample 4 (from http://claimsid.codeplex.com/) as template for our ADFS project.
We have no problem with passive requests to ADFS authenticated services. In the sample, the federation provider is a custom STS, and the sample works fine.

Now we wish to replace the custom federation provider (Adatum FP in the sample) with our own ADFS.

Our setup right now is as follows (Namespaces hidden)

• ServiceClient: Console Applicaton, calls Services
• Services: WCF Webservice, Single method returning a string. This as is default
  [Ordertracking.Services in sample]
• Services.Authentication: Our custom Identity Provider. This is as default [Litware.SimulatedIssuer in sample]
• ADFS: Our Federation Provider [FederationProvider.Adatum in
  example]

ServiceClient wants to call Services, and from configuration it knows it has to get a token from IP (Services.Authentication). The token is then passed to ADFS, who validates the token
and sends a new token back to ServiceClient. The client new passes the FP token to the service, and the service (being a relying party on ADFS) verifies the token against ADFS, and performs the service method.

The issue:

Replacing the STS in the example with ADFS, seems to break the integration. We seem to be getting the token from the IP back correctly, but we are running into problems when passing the IP token to ADFS.
It seems that we have a problem with our Audience Uri’s, but we have added

https://’adfs fqdn’/adfs/services/Trust/13/IssuedTokenMixedSymmetricBasic256

Client Exception
We get an MessageSecurityException in the client with this InnerException
InnerException
{“ID3242: The security token could not be authenticated or authorized.”}

We have added the audience uri to our IP Web.config:

<audienceUris mode="Always">
    <add value="https://<adfs fqdn>/adfs/services/Trust/13/IssuedTokenMixedSymmetricBasic256" />
</audienceUris>

If necessary we can post additional config files and screenshots of ADFS configuration.

Answer 1

This took a bit of work but we finally solved the problem. Instead of configuring this, we built the connection in code. I’m thinking we probably had an error somewhere in the client configuration.

Some advice to anyone trying this – build the connections in code first. The XML configuration is a bit harder to work with.

We found some sample code on leastprivilege.com

private static SecurityToken GetIdPToken()
    {

        var factory = new WSTrustChannelFactory(
            new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential),
            "https://systemidp.dk/Issuer.svc");
        factory.TrustVersion = TrustVersion.WSTrust13;

        factory.Credentials.UserName.UserName = "LITWARE\\rick";
        factory.Credentials.UserName.Password = "thisPasswordIsNotChecked";

        var rst = new RequestSecurityToken
        {
            RequestType = WSTrust13Constants.RequestTypes.Issue,
            AppliesTo = new EndpointAddress("https://adfsfqdn/adfs/services/trust"),
            KeyType = WSTrust13Constants.KeyTypes.Symmetric,
            ReplyTo = "https://adfsfqdn/adfs/services/trust/13/issuedtokenmixedsymmetricbasic256/"
        };
        factory.ConfigureChannelFactory();
        var channel = factory.CreateChannel();
        return channel.Issue(rst);
    }

    private static SecurityToken GetRSTSToken(SecurityToken idpToken)
    {
        var binding = new IssuedTokenWSTrustBinding();
        binding.SecurityMode = SecurityMode.TransportWithMessageCredential;

        var factory = new WSTrustChannelFactory(
            binding,
            "https://adfsfqdn/adfs/services/trust/13/issuedtokenmixedsymmetricbasic256/");
        factory.TrustVersion = TrustVersion.WSTrust13;
        factory.Credentials.SupportInteractive = false;

        var rst = new RequestSecurityToken
        {
            RequestType = WSTrust13Constants.RequestTypes.Issue,
            AppliesTo = new EndpointAddress("https://services.dk/WebService.svc"),
            KeyType = WSTrust13Constants.KeyTypes.Symmetric
        };

        factory.ConfigureChannelFactory();
        var channel = factory.CreateChannelWithIssuedToken(idpToken);
        return channel.Issue(rst);
    }

Creating a WCF call with the token

var ipdtoken = GetIdPToken();
var stsToken = GetRSTSToken(ipdtoken);
var binding = new WS2007FederationHttpBinding(WSFederationHttpSecurityMode.TransportWithMessageCredential);
binding.Security.Message.EstablishSecurityContext = false;
var factory = new ChannelFactory<IWebService>(binding, "https://services.dk/WebService.svc");

factory.ConfigureChannelFactory();
factory.Credentials.SupportInteractive = false;

var serviceChannel = factory.CreateChannelWithIssuedToken(stsToken);

var s = serviceChannel.GetUserInformation();
