Securing backend WCF service with WIF using ADFS2 as IP - wcf

Question

I’m having an issue using ADFS2 to secure a back-end WCF service that is being called from Passively Federated Website. I have the passive federation working on the website, but the back-end service is giving me problems.
The pieces of the puzzle.
Silverlight Client that is being served from Passively Federated Website.
The Silverlight calls a WCF service (App Service), hosted on the passively Federated Website.
I have SaveBootstrapToken set to true in the config.
From the App Service, I want to call a back-end WCF service using BootstrapToken with the ActAs scenarion.
Federated Website and Back-end WCF service are setup as separate RPs in the ADFS2, token encryption is turned on. Both are allowed to delegate.
Back-end Service configuration:
I have WIF incorporated into the pipeline using behavior extension.

Answer 1

I got this scenario working, here’s the solution for anyone interested.
Followed Dominick Baier’s post for ideas / code: http://leastprivilege.com/2010/10/14/wif-adfs-2-and-wcfpart-5-service-client-more-flexibility-with-wstrustchannelfactory/
I changed the back-end WCF service config to this:
<microsoft.identityModel>
<service>
<audienceUris>
<add value="https://localhost/Service/QuoteService.svc" />
<add value="https://localhost/Service/" />
</audienceUris>
<serviceCertificate>
<certificateReference x509FindType="FindByThumbprint" findValue="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
</serviceCertificate>
<issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<trustedIssuers>
<add thumbprint="000000000000000000000000000000000000" name="http://myADFSserver/adfs/services/trust" />
</trustedIssuers>
</issuerNameRegistry>
<certificateValidation certificateValidationMode="None" />

</message>
</security>
</binding>
</ws2007FederationHttpBinding>
</bindings>
<behaviors>

</system.serviceModel>
I’m no longer using WCF config on the client, it’s all done in code.
Here’s the client code:
public QuoteServiceClient()
{
SecurityToken actAsToken = this.GetDelegatedTokenUsername();
var binding = new WS2007FederationHttpBinding(WSFederationHttpSecurityMode.TransportWithMessageCredential);
binding.Security.Message.EstablishSecurityContext = false;
ChannelFactory<IQuoteServiceChannel> factory =
new ChannelFactory<IQuoteServiceChannel>(binding, new EndpointAddress(svcEndpoint));
factory.ConfigureChannelFactory<IQuoteServiceChannel>();
factory.Credentials.SupportInteractive = false;
this.channel = factory.CreateChannelWithIssuedToken<IQuoteServiceChannel>(actAsToken);
}
private SecurityToken GetDelegatedTokenUsername()
{
var binding = new UserNameWSTrustBinding();
binding.SecurityMode = SecurityMode.TransportWithMessageCredential;
//UserNameMixed is this endpoint "/adfs/services/trust/13/usernamemixed"
WSTrustChannelFactory trustChannelFactory = new WSTrustChannelFactory(binding, new EndpointAddress(UserNameMixed));
trustChannelFactory.TrustVersion = System.ServiceModel.Security.TrustVersion.WSTrust13;
trustChannelFactory.Credentials.SupportInteractive = false;
//Some User Account
//It's used to access the ADFS Server
//Act as is the actual Identity that Will be used.
//If you use one of windows bindings (ex. windowstransport), you wont need this.
//The AppPool identity will be used then.
trustChannelFactory.Credentials.UserName.UserName = #"domain\username";
trustChannelFactory.Credentials.UserName.Password = "password";
try
{
RequestSecurityToken rst = new RequestSecurityToken();
rst.RequestType = WSTrust13Constants.RequestTypes.Issue;
rst.AppliesTo = new EndpointAddress(ServiceAppliesTo);
//This part will give you identity of logged in user
rst.ActAs = new SecurityTokenElement(this.GetBootStrapToken());
var channel = trustChannelFactory.CreateChannel();
RequestSecurityTokenResponse rstr = null;
SecurityToken delegatedToken = channel.Issue(rst, out rstr);
return delegatedToken;
}
catch (Exception ex)
{
throw new Exception(ex.Message, ex);
}
finally
{
try
{
if (trustChannelFactory.State == CommunicationState.Faulted)
{
trustChannelFactory.Abort();
}
else
{
trustChannelFactory.Close();
}
}
catch (Exception)
{ }
}
}
private SecurityToken GetBootStrapToken()
{
ClaimsPrincipal myClaimsPrincipal = System.Web.HttpContext.Current.User as ClaimsPrincipal;
SecurityToken bootstrapToken = myClaimsPrincipal.Identities[0].BootstrapToken;
if (bootstrapToken == null)
{
throw new Exception("bootstrap tokein is null. Logout and try again.");
}
return bootstrapToken;
}
That is all good and dandy, except you will not have proper claims on the back-end WCF service. Using this great article I was able to sort out the claim stuff in ADFS: http://technet.microsoft.com/en-us/library/adfs2-identity-delegation-step-by-step-guide.aspx . Scroll down to Enabling Identity Delegation and Fixing Claims Issuance Rules at CONTOSODC. I also removed claim encryption from Passively Federated Website.
After doing this I have same claims in the app service and the back-end WCF service.
I hope this helps someone in the same boat as I was.
