How to set a custom Identity when calling Claim-Aware WCF Service and retrieve it the STS with WIF

Question

Hi everyone,

I created my custom Claim-Aware WCF Service and a Custom STS Service using the WIF SDK Template.

Everything works fine but I would like to define my own custom Identity when I call the service and retrieve it in the STS Service.

For example in the following code:

protected override IClaimsIdentity GetOutputClaimsIdentity(IClaimsPrincipal principal, RequestSecurityToken request, Scope scope)
{
   IClaimsIdentity callerIdentity = (IClaimsIdentity)principal.Identity;
   Console.WriteLine("\nRequest from: " + callerIdentity.Name + "\n");

   IClaimsIdentity outputIdentity = new ClaimsIdentity();

   // Create a name claim from the incoming identity.

   Claim nameClaim = new Claim(ClaimTypes.Name, callerIdentity.Name);

   // Create an 'Age' claim with a value of 25. In a real scenario, this may likely be looked up from a database.

   Claim ageClaim = new Claim("http://WindowsIdentityFoundationSamples/2008/05/AgeClaim", "25", ClaimValueTypes.Integer);

   outputIdentity.Claims.Add(nameClaim);
   Console.WriteLine("ClaimType : " + nameClaim.ClaimType);
   Console.WriteLine("ClaimValue : " + nameClaim.Value);
   Console.WriteLine();

   Console.WriteLine("ClaimType : " + ageClaim.ClaimType);
   Console.WriteLine("ClaimValue : " + ageClaim.Value);
   Console.WriteLine("===========================");

   outputIdentity.Claims.Add(ageClaim);

   return outputIdentity;
}

The "callerIdentity.Name" value that i get from "IClaimsPrincipal principal" in the method is always my Windows credentials "MyDoman\MyUserName". I'm calling the service from a Windows Form that contains Username and Password fields and I'd like to validate those credentials in the STS by retrieving a custom Identity. I don't want to use the Windows Credentials. My question is when I can define that? because I tried many thing and I always get the Windows domain and username in "callerIdentity.Name" attribute. Thanks!
