How to use the same authorization pipeline for WebAPI with SignalR - authentication

Question

I am adding signalr functionality to a website that only logged in users will have access to for communicating with each other. I also would like to use the same pipeline to allow azure worker roles to communicate with a user indicating job statuses for long running queue-based processes, running on their behalf. I found an example here at this url that outlines how to use the OAuth Bearer tokens with signalr: http://blog.marcinbudny.com/search?q=Authentication+signalr+OAuth+#.V5KBaY52xTM. The problem is that his example seems to turn off the OAuthBearerTokens which I am using in my code for web api authentication and authorization. Here is the code from the article:
//app.UseCookieAuthentication(new CookieAuthenticationOptions());
//app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
//app.UseOAuthBearerTokens(OAuthOptions);
app.UseOAuthAuthorizationServer(OAuthOptions);
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
{
Provider = new ApplicationOAuthBearerAuthenticationProvider(),
});
and this is my code utilizing the technique in this article:
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
PublicClientId = "self";
// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId, UserFactory),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(2),
AllowInsecureHttp = false
};
app.Map("/signalr", map =>
{
map.UseCors(CorsOptions.AllowAll);
map.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()
{
Provider = new QueryStringOAuthBearerAuthenticationProvider()
});
var hubConfiguration = new HubConfiguration
{
Resolver = GlobalHost.DependencyResolver,
};
map.RunSignalR(hubConfiguration);
});
How can I allow signalr to access the user's information in the same way I would for web api when there are times I will need worker role processes to pass information to clients as well as client-side code does?
