UseIdentityServerBearerTokenAuthentication is not working for IdentityServer3 - asp.net

Question

I have used the IdentityServer v3, now I want one website to be both the identity host and the web api host.
The authority option is not used to validate the token. I have verified the token endpoint and the token validation endpoint is working as expected (I can get and validate a token using postman). I used the [Authorize] attribute to decorate my controller method. Full logging is enabled on IdentityServer, nothing is logged when making an api request with a header name 'Authorization' with the value like 'Bearer mytokenhere'.
This is a vNext website on ASP.NET 5 using the Visual Studio 2015 CTP6.
app.UseMvc();
var certFile = AppDomain.CurrentDomain.BaseDirectory + "\\myawesomesite.pfx";
app.Map("/core", core =>
{
var factory = InMemoryFactory.Create(
users: Users.Get(),
clients: Clients.Get(),
scopes: Scopes.Get());
var idsrvOptions = new IdentityServerOptions
{
SiteName = "Lektieplan",
Factory = factory,
RequireSsl = false,
SigningCertificate = new X509Certificate2(certFile, "lektieplan"),
CorsPolicy = CorsPolicy.AllowAll,
LoggingOptions = new LoggingOptions { EnableWebApiDiagnostics = true,EnableHttpLogging = true, IncludeSensitiveDataInLogs = true, WebApiDiagnosticsIsVerbose = true }
};
core.UseIdentityServer(idsrvOptions);
});
app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
{
Authority = "http://localhost:57540/core",
RequiredScopes = new[] { "api1" },
});
And my project.json
My dependencies:
"Microsoft.AspNet.Server.IIS": "1.0.0-beta3",
"Microsoft.AspNet.Mvc": "6.0.0-beta3",
"Microsoft.AspNet.StaticFiles": "1.0.0-beta3",
"Microsoft.AspNet.Server.WebListener": "1.0.0-beta3",
"Thinktecture.IdentityServer3": "1.3.0.0",
"Microsoft.AspNet.Owin": "1.0.0.0-beta3",
"Microsoft.AspNet.Security.DataProtection": "1.0.0.0-beta3",
"Thinktecture.IdentityServer3.AccessTokenValidation": "1.2.2",
"Autofac": "4.0.0-alpha1",
"log4net": "2.0.3"
I seems to me that some of the provided samples works because of a cookie based option. I don't want to use the cookies.

Is UseIdentityServerBearerTokenAuthentication your only auth type? Do you have any filters defined for MVC?
I would try to split the apps into separate katana pipelines, so they don't conflict at all.
Pseudo:
app.Map("/core", a => a.UseIdsrv());
app.Map("/somethingweb", a => a.UseMvc());
app.Map("/api", a => {
a.UseBearerTokenAuth();
a.UseWebApi(); //or Mvc from now on, with v5
});
Guessing you would need to add cookieauth to that mvc pipeline as well, depending on what you want to achieve.
