Now you can log in to the Identity Portal and select "Register With Host".
Assuming:
- the on-premise relay service has a host id = bf1e3a54-91bb-496b-bda6-fdfd5faf4480
- the on-premise API has a user with user name = "Ackermann"
Then fill in the form appropriately:

Once this registration is successful, any client can now communicate with the on-premise API using the Cloud Relay Service, defined below.
##Cloud Relay Service##
Create a new ASP.NET Project (named e.g. "CloudRelayService") and select "Web Api".
- Before compiling and running the first time, make the same changes to the ApplicationUser class as mentioned above for the Identity Portal.
- Also, edit web.config and change the connection string for "DefaultConnection" to work with the same database as the Identity Portal by copying the connection string from that project.
- Important: if the connection string contains a `|DataDirectory|` reference in the file path, you will have to replace this with the true physical path to the other project, otherwise the two projects will not point to the same database file.
Add the following method to the AccountController (for this, you must include the System.Linq namespace):
~~~csharp
// GET api/Account/OnPremiseUserId
[HostAuthentication(DefaultAuthenticationTypes.ExternalBearer)]
[Route("OnPremiseUserId")]
public IHttpActionResult GetOnPremiseUserId()
{
// get the on-premise user id
var identity = (ClaimsIdentity)User.Identity;
var onPremiseUserIdClaim = identity.Claims.SingleOrDefault(c => c.Type == "OnPremiseUserId");
if (onPremiseUserIdClaim == null)
{
return Unauthorized();
}
return Ok(onPremiseUserIdClaim.Value);
}
~~~
Use `NuGet` to add "WindowsAzure.ServiceBus" to the project.
Also, add a reference to the OnPremiseRelay DLL, so that the IRelay WCF Interface, as well as the Request and Response classes, are known.
Then add a new controller `RelayController` with this code:
~~~csharp
[Authorize]
[RoutePrefix("relay")]
public class RelayController : ApiController
{
private void CopyIncomingHeaders(RequestDetails request)
{
var headers = HttpContext.Current.Request.Headers;
// copy all incoming headers
foreach (string key in headers.Keys)
{
request.Headers.Add(new Header
{
Key = key,
Value = headers[key]
});
}
}
[HttpGet]
[Route("{*url}")]
public async Task
