What Is a Novell 5.1 NDS Server?
Novell 5.1 NDS is a version of Novell's Netware file server that uses Netware Directory Services for network organization and management, similar to Microsoft Server's Active Directory. NDS defines the roles of different components in the network, and permissions of users within the network to use them. NDS uses a hierarchical structure to organize all aspects of computer network, including users, groups, computers, servers and printers.

Purpose
-
Before the introduction of NDS on Netware 4.x servers, if a network administrator wanted to add a new user or group of users to a Novell network, those new users had to be added to every server on the network. NDS made it possible to centralize this process, as all the servers on the network were able to share the same directory. NDS 5.1 was designed for use on Novell NetWare Servers, Windows 2000 Servers, Unix and Linux servers.
Structure
-
NDS 5.1 identifies all users and resources in a network as "objects" and defines them by the properties assigned to them. Objects are organized in a tree-like structure, with two types of objects: container objects and leaf objects. Container objects are much like folders, in that you can place other objects inside them including other Container objects. Leaf objects are the end points of the tree, such as computers, printers and users, and cannot contain other objects.

Container Objects
-
Four main container objects are in an NDS tree. An NDS tree begins with the Root object, which is created during installation of NDS and which contains all other objects. Three other types of objects can be created in the root. An Organization object is used to define the organization or company using the network. A Country object is used to define different countries in a multinational network. An Organization Unit object is used to divide different parts of the organization. Rights that are assigned to a container object are inherited by the objects it contains.
Leaf Objects
-
Leaf objects identify different components and users in the network. The types of objects in an NDS tree can vary depending on the programs used in the network, however most of these can be easily identifiable based on their names, such as Computer, Server, Printer, Print Server, and Print Queue objects. Volume and Directory Map objects can be created for each server in the network. A Group object can be used to manage groups of users in the network who have the same needs. A Template object can be used to quickly add new users to the network.
