ASP.NET Identity Across Subdomains

I'm trying to get the ASP.NET Identity to work on a parent domain. I was able to successfully configure the authentication cookie to be accessible from my parent domain by setting the CookiePath (.mydomain).

Although I'm not sure it is necessary, I also set a machinekey tag with the same values in the web.config of both projects.

Issue: Currently, even though the cookie is shared with my parent domain, it still does not seem to be registering that it is authenticated, even with the cookie there. I have an <authorization> tag to deny anonymous users, and my app is still redirecting to login page (located on subdomain).

Just in case this makes a difference: I am running these 2 projects on localhost from Visual Studio, with domain / subdomain configured on IISExpress. (Parent project is localhost.com and subdomain project, which does the authentication, is secure.localhost.com.)

I tried troubleshooting by checking if the user is authenticated with Request.GetOwinContext() on localhost.com (parent domain), however my application errors out on that line with the following:

No owin.Environment item was found in the context.

What else do I need to do to get ASP.NET identity working on my parent domain?

This is about the exception 'No owin.Environment item was found in the context.' from Request.GetOwinContext(). It usually means that the OWIN startup class detection failed.

Check the following: In both projects, you'll find the file Startup.cs in the root folder of each with the following code:

[assembly: OwinStartupAttribute(typeof(XXX.XXX.Startup))]
namespace Project.Web.Client
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

Make sure this code is executed on startup. More information here: http://www.asp.net/aspnet/overview/owin-and-katana/owin-startup-class-detection
