+# Basic auth is a first class citizen compatible with all the apps.  Login with the shadow file defined username/pass.
+# If the SERVER variable above is set to, for example, nettica.example.com, it will log you in as user@example.com,
+# removing the first label.  During login if you add a domain, such as user@example2.com, it will remove that
+# domain to validate the user, but preserve it for user creation, allowing for easy testing and evaluation of the product.
