Create Auth/UserDB/PasswordDB Demo
After a nice lunch with Xavier, the good idea he has is to create a Demo backend that will have hardcoded users.
This will be the default backend at installation, and will allow to start LL:NG with fake users, just to test it. We will have for example user1, user2 and admin. Access to Manager will be restricted to admin with configuration in lemonldap-ng.ini.
We will add a warning in Manager until the Demo backend is changed to another.
The PasswordDBDemo will do nothing, but will allow the password change form to be displayed.
