       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@.
