I'm trying to create a simple web service with ServiceStack. On the server (service) side, I've first created a user "administrator" and assigned it the "Admin" role. I'm using the ServiceStack built-in credentials authentication and I it authenticates nicely. However, any subsequent call to any webservice that is decorated with the [Authenticate] attribute returns a the following error: 

*No configuration was added for OAuth provider 'basic'*

FYI: the database is RavenDb - using ServiceStack.Authentication.RavenDb. I also registered a MemoryCacheClient in the App\_Start.AppHost.Configure(). Let me know if you need to see all code in App\_Start.AppHost class.

Server Code (excerpt):

```
namespace MyTest 
{
    [Route("/hello")]
    [Route("/hello/{Name}")]
    [Authenticate]
    public class Hello
    {
        public string Name { get; set; }
    }

    public class HelloResponse
    {
        public string Result { get; set; }
    }

    public class HelloService : Service
    {
        public IUserAuthRepository UserAuthRepo { get; set; }

        public object Any(Hello request)
        {
            return new HelloResponse { Result = "Hello, " + request.Name };
        }
    }
}
```

Client side:

```
var client = new JsonServiceClient("http://127.0.0.1:65385/auth/credentials?format=json");
var auth   = new Auth { UserName = "administrator", Password = "12345" };

var authResponse = client.Post(auth);

if (authResponse.ResponseStatus.ErrorCode == null)
{
    client = new JsonServiceClient("http://127.0.0.1:65385/hello");
    client.UserName = "administrator";
    client.Password = "12345";

    // When sending the request - it returns "Not Found"
    var helloResponse = client.Send(new Hello { Name = "John" });
}
```

**EDIT:**   

The web.config of my services looks exactly like written in section 2a of [the Hello World tutorial](http://www.servicestack.net/ServiceStack.Hello/)

Here's the configuration of my AppHost:

```
public override void Configure(Funq.Container container)
{
    container.Register(new MemoryCacheClient { FlushOnDispose = false });
    container.Register(new EmbeddableDocumentStore { DataDirectory = "Data" }.Initialize());

    ConfigureAuth(container);
}

private void ConfigureAuth(Funq.Container container)
{
    var appSettings = new AppSettings();

    Plugins.Add(new AuthFeature(() => new CustomUserSession(),
        new IAuthProvider[] {
            new CredentialsAuthProvider(appSettings)}));

    Plugins.Add(new RegistrationFeature());

    container.Register(
        new RavenUserAuthRepository(c.Resolve()));
}

```
