Syntax options:

       FROM identifier
       FROM PUBLIC

    Specifies the identifiers for the ACL entry to be modified
    or deleted. Specifying PUBLIC is equivalent to a wildcard
    specification of all user identifiers.

    You can specify foyr types of identifiers:

    o  User identifiers

    o  General identifiers

    o  System-defined identifiers

    o  Role names

    You can specify more than one identifier by combining them
    with plus signs (+).  Such identifiers are called  multiple
    identifiers. They identify only those users who are common to all
    the groups defined by the individual identifiers. Users who do
    not match all the identifiers are not controlled by that entry.

    For instance, the multiple identifier SECRETARIES + INTERACTIVE
    specifies only members of the group defined by the general
    identifier SECRETARIES that are interactive processes. It does
    not identify members of the SECRETARIES group that are not
    interactive processes.

    For more information about identifiers, see your operating system
    documentation.
