Authorization sample - Can't get passed login view with http

Just tested the Authorization sample. The non-secured url keeps redirecting to the login view.

Steps to reproduce:

• Go to http://localhost:5000 and enter the correct credentials. You are redirected to the login view.

Using the secured url https://localhost:5001 shows the home page with information and links after succesful login.

I'm using Firefox 64.0.2.
