For now we are only using http on an internal network. If you create a new user and check the Require user to change password box, the new user is NOT prompted to change password on first login. Login succeeds and the dashboard is displayed. If the user signs out and tries to sign in again, a change password dialog is displayed. After entering the new password, a black screen at this URL is displayed.
