OWIN and Forms Authentication with WEB API 2 with SPA

Question

I have a Web API 2 Project that is referenced by a SPA JavaScript application.

I'm using OWIN to authenticate the requests and upon login with Forms authentication, however, on each send back to the server my resources are not authenticated after I login.

App_Start/WebApiConfig.cs

namespace API
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            // Configure Web API to use only bearer token authentication.
            config.SuppressDefaultHostAuthentication();
            config.Filters.Add(new HostAuthenticationFilter(Startup.OAuthBearerOptions.AuthenticationType));

            config.EnableCors(new EnableCorsAttribute(
                origins: "*", headers: "*", methods: "*"));

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            // Use camel case for JSON data.
            config.Formatters.JsonFormatter.SerializerSettings.ContractResolver =
                new CamelCasePropertyNamesContractResolver();
        }
    }
}

/Startup.cs

[assembly: OwinStartup(typeof(API.Startup))]

namespace API
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

App_Start/Startup.Auth.cs

namespace API
{
    public partial class Startup
    {
        static Startup()
        {
            OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
        }

        public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }

        public void ConfigureAuth(IAppBuilder app)
        {
            app.UseCookieAuthentication(new CookieAuthenticationOptions());
            app.UseOAuthBearerAuthentication(OAuthBearerOptions);
        }
    }
}

Controllers/AccountController.cs

namespace API.Controllers
{
    public class AccountController : ApiController
    {

        public AccountController()
        {
            HttpContext.Current.Response.SuppressFormsAuthenticationRedirect = true;
        }

        [HttpPost]
        [AllowAnonymous]
        [Route("api/account/login")]
        [EnableCors(origins: "*", headers: "*", methods: "*", SupportsCredentials = true)]
        public HttpResponseMessage Login(LoginBindingModel login)
        {
            var authenticated = false;
            if (authenticated || (login.UserName == "a" && login.Password == "a"))
            {
                var identity = new ClaimsIdentity(Startup.OAuthBearerOptions.AuthenticationType);
                identity.AddClaim(new Claim(ClaimTypes.Name, login.UserName));

                AuthenticationTicket ticket = new AuthenticationTicket(identity, new AuthenticationProperties());
                var currentUtc = new SystemClock().UtcNow;
                ticket.Properties.IssuedUtc = currentUtc;
                ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromMinutes(30));

                var token = Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket);
                var response = new HttpResponseMessage(HttpStatusCode.OK)
                {
                    Content = new ObjectContent<object>(new  
                    { 
                        UserName = login.UserName,
                        AccessToken = token
                    }, Configuration.Formatters.JsonFormatter)
                };

                FormsAuthentication.SetAuthCookie(login.UserName, true);

                return response;
            }

            return new HttpResponseMessage(HttpStatusCode.BadRequest);
        }

        [HttpGet]
        [Route("api/account/profile")]
        [Authorize]
        public HttpResponseMessage Profile()
        {
            return new HttpResponseMessage(HttpStatusCode.OK)
            {
                Content = new ObjectContent<object>(new
                {
                    UserName = User.Identity.Name
                }, Configuration.Formatters.JsonFormatter)
            };
        }
    }
}

Then I invoke it with JavaScript like:

       $httpProvider.defaults.withCredentials = true;

       login: function(user, success, error) {
            return $http.post('/api/account/login', user);
        },

        profile:function(){
            return $http.get('/api/account/profile');
        }

My cookies are set on the browser:

ASPXAUTH 040E3B4141C86457CC0C6A10781CA1EFFF1A32833563A6E7C0EF1D062ED9AF079811F1600F6573181B04FE3962F36CFF45F183378A3E23179E89D8D009C9E6783E366AF5E4EDEE39926A39E64C76B165

but after login, further requests are deemed unauthorized...

Status Code:401 Unauthorized

I feel like I'm REALLY close just missing one little piece, anyone got any ideas?

Are you using Bearer token from your app? If you didn't use it and just want to use cookie, please remove following code:

        // Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(Startup.OAuthBearerOptions.AuthenticationType));

The code above will only allow bearer authentication for web api.

And you may also remove app.UseOAuthBearerAuthentication(OAuthBearerOptions); to remove bearer authentication middleware from OWIN pipeline.

If you want to use bearer token in your app, you need to set the token before sending ajax request in browser.

Way too long to post but added all the details on how to set this up on github gist.
