eDirectory

NetWare 6.5s directory database

System for organizing and managing multiple servers and their

resources

Similar to Active Directory in Windows Server 2003

Treat every networked resource as separate object with distinct attributes

Objects belong to classes

eDirectory information stored in database that supports LDAP

Compatible with other NOS and Internet directories

Schema: defined set of object classes and their properties

Base schema: simple schema installedby default with eDirectory

Extended schema: changes made tobase schema

Trees and OUs:

Hierarchical organization

Tree can have one root

Tree Object


17/42

Trees and OUs (continued):

Below root is an organization object

Branches out in hierarchical arrangement ofOUs

A user is a leaf object

Naming Conventions:

Each eDirectory tree object has a context

Indicates where object belongs in the tree

Consists of objects OU names, arranged from specific to general, plus

organization name

Typeful and typeless contexts

Planning for Installation

Poor planning results in more work for installer, potential downtimefor users, and headaches for whomever supports server afterinstallation

Critical preinstallation decisions:

Where does the server fit in the eDirectory tree?

After servers context established, cannot change it

What name will the server have?

How many and what kinds of NICs will the server use?

What protocols and network services should the server use?


23/42

Confidential23

Planning for Installation (continued)

Critical preinstallation decisions (continued):

What will the Administrator password be?

What kind of disk controllers does the server have?

How many, how large, and what kind of volumes will the server require?

Initially all free space on hard disk assigned to default volume, SYS

What server pattern, or type, will the serverbe?

What kind of license do I have?

How can I remember all of this information?

Installing and Configuring a NetWare 6.5 Server:

The Installation Process

Installed from CD or another server on network

Installation tasks:

Select language

Select regional settings

Accept License Agreements

Choose Default or Manual installation

Prepare boot partition

Choose pattern

Select components to install (Manual installation)

Copy files


25/42

Confidential25

The Installation Process (continued)

Tasks to set up server:

Name server

Enable cryptography

Specify network protocols for each network adapter

If TCP/IP, specify servers IP addressing information

Enter servers host and domain name

New eDirectory tree or add server to existing tree?

Enter eDirectory information

Choose an Administrator ID and password

Select login method


26/42

Confidential26

Establishing Users and Groups

Need to add objectsincluding user objectsto eDirectory tree

Use ConsoleOne, Remote Manager, or iManager

To run ConsoleOne, computer must have ConsoleOne clientinstalled

Running same protocols as server

To run Remote Manager, point Webbrowser to IP address of server

management interface By default, port 8008 on server


27/42

Confidential27

Establishing Users and Groups (continued)

To start iManager, point browser to /nps/imanager.html page on

server

After eDirectory objects created, may want to change properties

Home directory: directory in which user can store files

By default, users have full access privileges to files and subdirectories

within their home directories

Traditional Client Access

Clients running Windows, Macintosh, and UNIX-type ofOSs

traditionally connected via a Novell client specifically designed for

that client

Client must have appropriate protocol suite installed

May require additional client software

Novell provides utilities to automatically install client software (and

updates) on all clients

Native File Access

NetWare capable of providing clients with direct access to NSS

using clients native file access protocols

Users can browse folders and directories as if connected to server

running same file access protocols

All file access protocols installed by default

Network administrator must set up network share for each protocol

Via iManager


34/42

Native File Access (continued)

Client must run same protocols and software normally used to

connect to a server natively running its file access protocols

NetDrive: When installed on Windows clients, allows access to

directories on NetWare 6.5 server

Uses IPs such as HTTP and FTP

Summary

With NetWare 6.x, Novell has maintained its NOSs traditional file-and print-sharing strengths while adding browser-basedmanagement tools; popular open source Web development tools; afast, efficient file system; and flexible methods for managing multipleservers, volumes, and storage objects

The NetWare Integrated Kernel is responsible for overseeing allcritical NetWare server processes

NLMs are routines that enable the server to run a range of programsand offer a variety of services


40/42

Summary (continued)

Using ConsoleOne, administrators can manage servers, volumes,disks, and eDirectory objects

iManager is the primary means of managing eDirectory objects inNetWare 6.5

NSS offers many advantages over traditional file systems, includingfaster access, more efficient use of memory, file compression,support of files or directories as large as 8 TB, support for sharing asingle application over multiple servers, capability to limit userdirectory and volume size, and browser-based management tools


41/42

Confidential41

Summary (continued)

eDirectory is NetWare 6.xs system for organizing and managingmultiple servers and their resources, including storage devices,users, volumes, groups, printers, and so on

The word schema refers to eDirectorys defined set of objectclasses and their properties

eDirectory follows a tree structure

Each object has a context that indicates where that object belongs inthe eDirectory tree

NetWare recognizes two naming conventions for a users context:typeful and typeless


42/42

Confidential42

Summary (continued)

User and Group objects can be created through ConsoleOne,

Remote Manager, or iManager

Clients can connect to a NetWare 6.5 server, browse directories,

and manage files in one of several different ways

NetWare 6.5 uses the DirXML tool to share data between eDirectory

and Active Directory or Windows NT domains

Nterprise Linux Services integrates NetWare and Linux clients and

servers
