Netware Directory Services
     
         (NDS) {Novell, Inc.}'s {directory services} for
        {Netware}, {Windows NT}, and {Unix}.  The NDS directory
        represents each {network} resource (user, hardware, or
        application) as an {object} of a certain {class}, where each
        class has certain properties.  For example, User and Print
        Server are object classes and a user has over 80 properties
        such as name, login, password, department, and title.
     
        The directory is hierarchical, divided into branches by {rules
        of containment}.  A given object can only belong to a given
        container (or branch).  The rules governing classes,
        properties and, {rules of containment} are known as the
        {schema}.
