/LIKE=(NAME=source-object-name
     [,CLASS=source-object-class]  [,PROFILE=TEMPLATE=template-name])

    Identifies the object from which SET SECURITY should copy
    security elements. The /LIKE qualifier replaces an object's
    existing elements with those of the source object. Nopropagate
    ACEs are not transferred and protected ACEs on the target object
    are not deleted. Use the /COPY_ATTRIBUTE qualifier with the /LIKE
    qualifier to copy an object's elements. See the VSI OpenVMS Guide
    to System Security for information about the special handling of
    protected and nopropagate ACEs.

    The object class of the source object defaults to the class of
    the target object. When the /CLASS qualifier is omitted, the
    CLASS keyword defaults to FILE.

    The PROFILE keyword applies to security class objects. It
    identifies which template of the security class you want to copy
    and modify. See /PROFILE for more information.
