 How to Use multiple User Providers
 ==================================
 
-Each authentication mechanism (e.g. HTTP Authentication, form login, etc)
-uses exactly one user provider, and will use the first declared user provider
-by default. But what if you want to specify a few users via configuration
-and the rest of your users in the database? This is possible by creating
-a new provider that chains the two together:

-    In previous Symfony versions, firewalls that didn't define their user provider
-    explicitly, used the first existing provider (``chain_provider`` in this

-    in Symfony 3.4 and will throw an exception in 4.0. Always define the provider
-    used by the firewall when there are multiple providers.

 You can also configure the firewall or individual authentication mechanisms
