symfonyのsecurity設定

  .settings:
    login_module: default  # To be called when a non-authenticated user
    login_action: login    # Tries to access a secure page
                           # 
    
    secure_module: default # To be called when a user doesn't have
    secure_action: secure  # The credentials required for an action 

二つの違いは、credentials を調べるか、authenticationを調べるかの違いらしい。
