FNS policies contain all the XFN policies plus extensions for the Solaris environment.
Computing environments now offer worldwide scope and a large range of services. Users expect to have access to services at every level of the computing environment. FNS policies provide a common framework for the three levels of services: global, enterprise, and application.
FNS provides to applications a set of policies on how name services are arranged and used:
Policies that specify how to federate the enterprise namespace so that it is accessible in the global namespace.
Policies that specify the names and bindings present in the initial context of every process.
Name service policies for enterprise objects: organizations, hosts, users, sites, files, and services.
Policies that define the relationships among the organization, host, user, site, files, and service enterprise objects.
Policies that specify the syntax of names used to refer to those enterprise objects.
