Syntax options:

    TO identifier | TO PUBLIC

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

    You can specify four 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.

    The following arguments briefly describe the three types of
    identifiers. For more information about identifiers, see your
    operating system documentation.
