We moved to a new server and my Thinktecture IdentityModel stuff broke.
Here's a super simplified repro sample. This works run locally from Visual Studio, but deployed to the server the handler is clearly not handling.
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
using Thinktecture.IdentityModel.Tokens.Http;
namespace WebApplication1
{
public class WebApiApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configuration.MessageHandlers.Add(
new AuthenticationHandler(CreateConfiguration()));
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
private AuthenticationConfiguration CreateConfiguration()
{
var config = new AuthenticationConfiguration
{
EnableSessionToken = true,
RequireSsl = false,
SendWwwAuthenticateResponseHeaders = false
};
config.AddBasicAuthentication(
(username, password) => { return username == password; });
return config;
}
}
}
The handler is not executing. I have set up remote debugging and this revealed that
- The Thinktecture assembly is loaded
- Application_Start creates and adds a basic auth handler
This script is the test client
<script>
$(document).ready(function () {
var u = "bilbo";
var p = "bilbo";
var btoken = btoa(u + ":" + p);
$.ajax({
url: "api/token",
headers: { Authorization: "Basic " + btoken },
}).then(function (result) {
document.write("auth ok");
}).fail(function (error) {
document.write("auth fail");
});
});
</script>
It produces a request for api/token decorated with a basic auth header as shown:
GET http://assa.com.au/api/token HTTP/1.1
Accept: */*

Visual Studio 2013 is showing valid breakpoints in the handler but they are not hit. This is why I believe the handler is not being invoked.
The response specifies a realm, but modifying handler registration to specify realm = "assa.com.au" did not affect the outcome.
