I see that I can add Nancy to my Azure Mobile app. http://www.strathweb.com/2014/02/running-owin-pipeline-new-net-azure-mobile-services/ , but how to add authentication for Nancy? The goal here is to have both a web application and a mobile application using the same server.
Purpose . If the Nancy page requires authentication, go to ~ / .auth / login / aad (for example), and then return to the original page.
Where I am:
- New Azure App for ASP.NET Mobile Applications Created
 - Added by Nancy
 Delete default MobileAppConfig and replace with
    new MobileAppConfiguration()
        .MapApiControllers()
        .AddTables(
            new MobileAppTableConfiguration()
                .MapTableControllers()
                .AddEntityFramework()
        )
        .AddPushNotifications()
        .MapLegacyCrossDomainController()
        .ApplyTo(config);
Create an IndexModule and Confirm Nancy Works
public IndexModule()
{
    Get["/"] = _ => "Hello";
}
Create an AdminModule, RequiresAuthentication will appear after installing Nancy.Authentication.Forms
public AdminModule()
    : base("admin")
{
    Get["/"] = _ =>
    {
        this.RequiresAuthentication();
        return "This is admin";
    };
}
Maybe wrong, but I
protected override void ConfigureRequestContainer(TinyIoCContainer container, NancyContext context)
{
    base.ConfigureRequestContainer(container, context);
    container.Register<IUserMapper, UserMapper>();
}
protected override void RequestStartup(TinyIoCContainer container, IPipelines pipelines, NancyContext context)
{
    base.RequestStartup(container, pipelines, context);
    var formsAuthConfig = new FormsAuthenticationConfiguration
    {
        RedirectUrl = "~/.auth/login/aad",
        UserMapper = container.Resolve<IUserMapper>(),
    };
    FormsAuthentication.Enable(pipelines, formsAuthConfig);
}
This means, and (3) still does not work.Update. Nancy.Forms.Authentication seems to be causing this. Can I use UseCookieAuthenticationfrom Owin.Security?
Update2. I got rid of Nancy.Forms.Authentication. It seems that when Zumo completes the authentication, owin server.user is actually installed.
    protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)
    {
        base.ApplicationStartup(container, pipelines);
        Csrf.Enable(pipelines);
        pipelines.BeforeRequest.AddItemToStartOfPipeline(FlowPrincipal);
    }
    private Response FlowPrincipal(NancyContext context)
    {
        var env = Get<IDictionary<string, object>>(context.Items, NancyMiddleware.RequestEnvironmentKey);
        if (env != null)
        {
            var principal = Get<IPrincipal>(env, "server.User") as ClaimsPrincipal;
            if (principal != null)
            {
                context.CurrentUser = new ClaimsPrincipalUserIdentity(principal);
            }
        }
        return null;
    }
Will issue a valid user. However, how to call login and redirection is another question.
Update3. I was able to force login using setting in Azure
