-## Usage
+### Configuring Ldap
+The Ldap related code depends on [`zend-ldap`](https://github.com/zendframework/zend-ldap), so all configuration options are just passed through.
+For more details check the [`zend-ldap docs`](http://framework.zend.com/manual/current/en/index.html#zend-ldap).
 
-### Register per firewall
-$app->register(new LdapAuthenticationServiceProvider(), $options);
 
+### Custom user class
+The LdapUserProvider class allows to configure a custom User class to be used. Only restriction is that the custom class has a constructor that is compatible with the default class `Symfony\\Component\\Security\\Core\\User\\User`.
