/*
   There are several special identifiers ("who") which need to be
   understood universally, rather than in the context of a particular
   DNS domain.  Some of these identifiers cannot be understood when an
   NFS client accesses the server, but have meaning when a local process
   accesses the file.  The ability to display and modify these
   permissions is permitted over NFS, even if none of the access methods
   on the server understands the identifiers.

    Who                    Description
   _______________________________________________________________

   "OWNER"                The owner of the file.
   "GROUP"                The group associated with the file.
   "EVERYONE"             The world.
   "INTERACTIVE"          Accessed from an interactive terminal.
   "NETWORK"              Accessed via the network.
   "DIALUP"               Accessed as a dialup user to the server.
   "BATCH"                Accessed from a batch job.
   "ANONYMOUS"            Accessed without any authentication.
   "AUTHENTICATED"        Any authenticated user (opposite of
                          ANONYMOUS)
   "SERVICE"              Access from a system service.

   To avoid conflict, these special identifiers are distinguish by an
   appended "@" and should appear in the form "xxxx@" (note: no domain
   name after the "@").  For example: ANONYMOUS@.
