The idea is that each service's data will only be accessible to a particular role (e.g. Role Commune1_Water will be able to access only Commune1_Water service).
Now, I've been running into some front-end issues with my layer list widget: users would like to be able to group the services by commune, but keep access limited by service.
My question: Is there a way to publish a single service including all three networks (water, communications, and electricity) and still be able to block access within the service? Currently, I block access via ArcGIS for Server, locking the services for particular roles.
