Remove standalone provider settings

[regniets]

In Configuration/Settings.yaml the below lines are production code even though only needed for standalone case.
I would be happy if those could be examplified (as comment).
In my (very specialized) case the authentication had failed every time until i completely removed this setting.
If needed, it can be added easily in the project's settings.

security:  
  authentication:  
    providers:   
      'Sandstorm.UserManagement:Login':  
        provider: 'PersistedUsernamePasswordProvider'  
        entryPoint: 'WebRedirect'  
        entryPointOptions:  
          routeValues:  
            '@package': 'Sandstorm.UserManagement'  
            '@controller': 'Login'  
            '@action': 'login'
