About This Guide
Welcome to Netscape Directory Server (Directory Server). This manual provides a
high-level overview of design and planning decisions you need to make before
installing the Directory Server, and describes the different installation methods that
you can use.
This preface contains the following sections:
• Prerequisite Reading (page 7)
• Directory Server Overview (page 7)
• Conventions Used In This Guide (page 8)
• Related Information (page 9)
Prerequisite Reading
Before you install Directory Server, we recommend that you read the Netscape
Directory Server Deployment Guide.Thisguidecoverskeyconceptsonhowto
design and plan your directory service.
After you finish planning your directory service, follow the steps in this installation
guide to install the Directory Server and its related software components.
Directory Server Overview
The major components of Directory Server include:
•An LDAP server—The core of the directory service, provided by the ns-slapd
daemon, and compliant with the LDAP v3 Internet standards.

Conventions Used In This Guide
8 Netscape Directory Server Installation Guide • March 2002
•Directory Server Console—An improved management console that
dramatically reduces the effort of setting up and maintaining your directory
service. The directory console is part of Netscape Console, the common
management framework for Netscape servers.
•SNMP Agent—Permits you to monitor your directory server in real time using
the Simple Network Management Protocol (SNMP).
•Online backup and restore—Allows you to create backups and restore from
backups while the server is running.
Conventions Used In This Guide
This section explains the conventions used in this book.
Monospaced font—Thistypefaceisusedforanytextthatappearsonthecomputer
screen or text that you should type. It is also used for filenames, functions, and
examples.
The greater than symbol (>) is used as a separator for successive menu selections.
For example, Object > New > User means that you should pull down the Object
menu, drag the mouse down to highlight New, and drag the mouse across to the
New submenu in which you must select User.
Throughout this book you will see path references of the form:
/usr/netscape/servers/slapd-serverID/...
The /usr/netscape/servers directory is the default installation directory. If you
have installed Directory Server in a different location, you should adapt the path
accordingly. serverID represents the server identifier you gave the server when you
installed it. For example, if you gave the server an identifier of phonebook,thenthe
actual path would be:
/usr/netscape/servers/slapd-phonebook/. . .
All paths specified in this manual are in UNIX format. If you are using a Windows
NT-based directory server, you should assume the NT equivalent file paths
whenever UNIX file paths are shown in this guide.
NOTE Notes and Cautions mark important information. Make sure you
read the information before continuing with a task.

Chapter 1
Preparing for a Directory Server
Installation
Before you begin installing Netscape Directory Server (Directory Server), you
should have an understanding of the various Directory Server components and the
design and configuration decisions you need to make.
To help you prepare for your Directory Server installation, you should be familiar
with the concepts contained in the following sections:
• Installation Components (page 11)
• Configuration Decisions (page 12)
• Installation Process Overview (page 19)
• Installation Privileges (page 20)
The Netscape Directory Server Deployment Guide contains basic directory concepts as
well as guidelines to help you design and successfully deploy your directory
service. Be sure you understand the concepts presented in this manual before
proceeding with the installation process.
Installation Components
Directory Server contains the following software components:
•Netscape Console—Netscape Console provides the common user interface for
all Netscape server products. From it you can perform common server
administration functions such as stopping and starting servers, installing new
server instances, and managing user and group information. Netscape Console
can be installed as a stand-alone application on any machine. You can also
install it on your network and use it to manage remote servers.

Configuration Decisions
12 Netscape Directory Server Installation Guide • March 2002
•Netscape Administration Server—Administration Server is a common
front-end to all Netscape servers. It receives communications from Netscape
Console and passes those communications on to the appropriate Netscape
server. Your site will have at least one Administration Server for each server
root in which you have installed an Netscape server.
•Directory Server—Directory Server is Netscape’s LDAP implementation. The
Directory Server runs as the ns-slapd process (on UNIX) or slapd service (on
WindowsNT,andWindows2000).Thisistheserverthatmanagesthe
directory databases and responds to client requests. Directory Server is a
required component.
The order in which you install and configure the various components depends on
whether you are performing a new installation or an upgrade. See “Installation
Process Overview,” on page 19 for details.
Configuration Decisions
During Directory Server installation, you are prompted for basic configuration
information. Decide how you are going to configure these basic parameters before
you begin the installation process. You are prompted for some or all of following
information, depending on the type of installation that you decide to perform:
• Port number; see “Choosing Unique Port Numbers,” on page 13.
• Server root; see “Creating a New Server Root,” on page 13.
• Users and groups to run the server as; see “Deciding the User and Group for
Your Netscape Servers (UNIX only),” on page 14.
• Your directory suffix; see “Determining Your Directory Suffix,” on page 16.
• Several different authentication user IDs; see “Defining Authentication
Entities,” on page 15.
• The location of the configuration and user Directory Servers; see “Determining
the Location of the Configuration Directory,” on page 16 and “Determining the
Location of the User Directory”.
• The administration domain; see “Determining the Administration Domain,”
on page 18.

Configuration Decisions
Chapter 1 Preparing for a Directory Server Installation 13
Choosing Unique Port Numbers
Port numbers can be any number from 1 to 65535. Keep the following in mind
when choosing a port number for your Directory Server:
• The standard Directory Server (LDAP) port number is 389.
• Port 636 is reserved from LDAP over SSL. Therefore, do not use port number
636 for your standard LDAP installation, even if 636 is not already in use. You
can also use LDAP over TLS on the standard LDAP port.
• Port numbers between 1 and 1024 have been assigned to various services by
the Internet Assigned Numbers Authority. Do not use port numbers below
1024 other than 389 or 636 for directory services as they will conflict with other
services.
• On UNIX platforms, Directory Server must be run as root if it will listen on
either port 389 or 636.
• On Windows NT and Windows 2000, the directory service must have
administrative privileges if it will use ports 389 or 636.
• Make sure the ports you choose are not already in use. Additionally, if you are
using both LDAP and LDAPS communications, make sure the port numbers
chosen for these two types of access are not identical.
For information on how to set up LDAP over SSL (LDAPS) for Directory Server,
see the Netscape Directory Server Administrator’s Guide.
Creating a New Server Root
Your server root is the directory where you install your Netscape servers. The
default server root for Directory Server is /usr/netscape/servers.
The server root must meet the following requirements:
• The server root must be a directory on a local disk drive; you cannot use a
networked drive for installation purposes. The file sharing protocols such as
AFS, NFS and SMB do not provide file locking and performance suitable for
use by the Directory Server. The server database index files may be damaged if
they are not held on a local file system.
• The directory must not already exist or must be empty.
• The server root directory must not be the same as the directory from which you
are running the setup program.

Configuration Decisions
14 Netscape Directory Server Installation Guide • March 2002
By default, the server root directory is one of the following:
•/usr/netscape/servers (on UNIX systems)
•c:\netscape\servers (on Windows NT and Windows 2000 systems)
Deciding the User and Group for Your Netscape
Servers (UNIX only)
For security reasons, it is always best to run UNIX-based production servers with
normal user privileges. That is, you do not want to run Directory Server with root
privileges. However, you will have to run Directory Server with root privileges if
you are using the default Directory Server ports. If Directory Server is to be started
by Administration Server, Administration Server must run either as root or as the
same user as Directory Server.
Youmustthereforedecidewhatuseraccountsyouwilluseforthefollowing
purposes:
• The user and group under which you will run Directory Server.
If you will not be running the directory server as root, it is strongly
recommended that you create a user account for all Netscape servers. You
should not use any existing operating system account, and must not use the
nobody account. Also you should create a common group for the directory
server files; again, you must not use the nobody group.
• The user and group under which you will run Administration Server.
For installations that use the default port numbers, this must be root. However,
if you use ports over 1024, then you should create a user account for all
Netscape servers, and run Administration Server as this account.
As a security precaution, when Administration Server is being run as root, it
should be shut it down when it is not in use.
You should use a common group for all Netscape servers, such as gid Netscape,
to ensure that files can be shared between servers when necessary.
Before you can install Directory Server and Administration Server, you must make
sure that the user and group accounts you will use exist on your system.

Configuration Decisions
Chapter 1 Preparing for a Directory Server Installation 15
Defining Authentication Entities
As you install Directory Server and Administration Server, you will be asked for
various user names, distinguished names (DN), and passwords. This list of login
and bind entities will differ depending on the type of installation that you are
performing:
• Directory Manager DN and password.
The Directory Manager DN is the special directory entry to which access
control does not apply. Think of the directory manager as your directory’s
superuser. (In former releases of Directory Server, the Directory Manager DN
was known as the root DN).
The default Directory Manager DN is cn=Directory Manager.Becausethe
Directory Manager DN is a special entry, the Directory Manager DN does not
have to conform to any suffix configured for your Directory Server. Therefore,
you must not manually create an actual Directory Server entry that has the
same DN as the directory manager DN.
The Directory Manager password must be at least 8 characters long, and is
limited to ASCII letters, digits, and symbols.
• Configuration Directory Administrator ID and password.
The configuration directory administrator is the person responsible for
managing all the Netscape servers accessible through Netscape Console. If you
log in with this user ID, then you can administer any Netscape server that you
can see in the server topology area of Netscape Console.
For security, the configuration directory administrator should not be the same
as the directory manager. The default configuration directory administrator ID
is admin.
• Administration Server User and password.
You are prompted for this only during custom installations. The
Administration Server user is the special user that has all privileges for the
local Administration Server. Authentication as this person allows you to
administer all the Netscape servers stored in the local server root.
Administration Server user ID and password is used only when the Directory
Server is down and you are unable to log in as the configuration directory
administrator. The existence of this user ID means that you can access
Administration Server and perform disaster recovery activities such as starting
Directory Server, reading log files, and so forth.

Configuration Decisions
16 Netscape Directory Server Installation Guide • March 2002
Normally, Administration Server user and password should be identical to the
configuration directory administrator ID and password.
Determining Your Directory Suffix
A directory suffix is the directory entry that represents the first entry in a directory
tree. You will need at least one directory suffix for the tree that will contain your
enterprise’s data. It is common practice to select a directory suffix that corresponds
to the DNS host name used by your enterprise. For example, if your organization
uses the DNS name example.com, then select a suffix of dc=example,dc=com.
For more information on planning the suffixes for your directory service, see the
Netscape Directory Server Deployment Guide.
Determining the Location of the Configuration
Directory
Many Netscape servers, including Directory Server 6.0, use an instance of
Directory Server to store configuration information. This information is stored in
the o=NetscapeRoot directory tree. It does not need to be held on the same
Directory Server as your directory data. Your configuration directory is the Directory
Server that contains the o=NetscapeRoot tree used by your Netscape servers.
If you are installing Directory Server only to support other Netscape servers, then
that Directory Server is your configuration directory. If you are installing Directory
Server to use as part of a general directory service, then you will have multiple
Directory Servers installed in your enterprise and you must decide which one will
host the configuration directory tree, o=NetscapeRoot. You must make this
decision before you install any Netscape servers (including Directory Server).
For ease of upgrades, you should use a Directory Server instance that is dedicated
to supporting the o=NetscapeRoot tree; this server instance should perform no
other function with regard to managing your enterprise’s directory data. Also, do
not use port 389 for this server instance because doing so could prevent you from
installing a Directory Server on that host that can be used for management of your
enterprise’s directory data.
Because the configuration directory normally experiences very little traffic, you can
allow its server instance to coexist on a machine with another more heavily loaded
Directory Server instance. However, for very large sites that are installing a large
number of Netscape servers, you may want to dedicate a low-end machine to the

Configuration Decisions
Chapter 1 Preparing for a Directory Server Installation 17
configuration directory so as to not hurt the performance of your other production
servers. Netscape server installations result in write activities to the configuration
directory. For large enough sites, this write activity could result in a short-term
performance hit to your other directory activities.
Also, as with any directory installation, consider replicating the configuration
directory to increase availability and reliability. See the Netscape Directory Server
Deployment Guide for information on using replication and DNS round robins to
increase directory availability.
Determining the Location of the User Directory
Just as the configuration directory is the Directory Server that is used for Netscape
server administration, the user directory is the Directory Server that contains the
entries for users and groups in your enterprise.
For most directory installations, the user directory and the configuration directory
should be two separate server instances. These server instances can be installed on
the same machine, but for best results you should consider placing the
configuration directory on a separate machine.
Between your user directory and your configuration directory, it is your user
directory that will receive the overwhelming percentage of the directory traffic. For
this reason, you should give the user directory the greatest computing resources.
Because the configuration directory should receive very little traffic, it can be
installed on a machine with very low-end resources (such as a minimally-equipped
Pentium).
CAUTION Corrupting the configuration directory tree can result in the necessity of
reinstalling all other Netscape servers that are registered in that
configuration directory. Remember the following guidelines when dealing
with the configuration directory:
• Always back up your configuration directory after you install a new
Netscape server.
• Never change the host name or port number used by the configuration
directory.
• Never directly modify the configuration directory tree. Only the setup
program for the various Netscape servers should ever modify the
configuration.

Configuration Decisions
18 Netscape Directory Server Installation Guide • March 2002
Also, you should use the default directory ports (389 and 636) for the user
directory. If your configuration directory is managed by a server instance
dedicated to that purpose, you should use some non-standard port for the
configuration directory.
You cannot install a user directory until you have installed a configuration
directory somewhere on your network.
Determining the Administration Domain
The administration domain allows you to logically group Netscape servers
together so that you can more easily distribute server administrative tasks. A
common scenario is for two divisions in a company to each want control of their
individual Netscape servers. However, you may still want some centralized
control of all the servers in your enterprise. Administration domains allow you to
meet these conflicting goals.
Administration domains have the following qualities:
• All servers share the same configuration directory, regardless of the domain
they belong to.
• Servers in two different domains may use two different user directories for
authentication and user management.
• The configuration directory administrator has complete access to all installed
Netscape servers, regardless of the domain that they belong to.
• Each administration domain can be configured with an administration domain
owner. This owner has complete access to all the servers in the domain but
does not have access to the servers in any other administration domain.
• The administration domain owner can grant individual users administrative
access on a server by server basis within the domain.
For many installations, you can have just one administration domain. In this case,
choose a name that is representative of your organization. For other installations,
you may want different domains because of the demands at your site. In the latter
case, try to name your administration domains after the organizations that will
control the servers in that domain.
For example, if you are an ISP and you have three customers for whom you are
installing and managing Netscape servers, create three administration domains
each named after a different customer.

Installation Process Overview
Chapter 1 Preparing for a Directory Server Installation 19
Installation Process Overview
You can use one of several installation processes to install Directory Server. Each
one guides you through the installation process and ensures that you install the
various components in the correct order.
The following sections outline the installation processes available, how to upgrade
from an earlier release of Directory Server, and how to unpack the software to
prepare for installation.
Selecting an Installation Process
You can install Directory Server software using one of the four different installation
methods provided in the setup program:
•Express Installation. Use this if you are installing for the purposes of
evaluating or testing Directory Server. Express installation is described in
“Using Express Installation,” on page 45.
•Typical Installation. Use this if you are performing a normal install of
Directory Server. Typical installation is described in “Using Typical
Installation,” on page 47.
•Custom Installation. In Directory Server 6.0, the custom installation process is
very similar to the typical installation process. The main difference is that the
custom installation process will allow you to import an LDIF file to initialize
the user directory database that is created by default.
•Silent Installation. Use this if you want to script your installation process. This
is especially useful for installing multiple consumer servers around your
enterprise. Silent install is described in Chapter 4, “Silent Installation.”
Beyond determining which type of installation process you will use, the process for
installing Directory Server is as follows:
1. Plan your directory service. By planning your directory tree in advance, you
can design a service that is easy to manage and easy to scale as your
organization grows. For guidance on planning your directory service, refer to
the Netscape Directory Server Deployment Guide.
2. Install your Directory Server as described in this manual.

Installation Privileges
20 Netscape Directory Server Installation Guide • March 2002
3. Create the directory suffixes and databases. You do not have to populate your
directory now; however, you should create the basic structure for your tree,
including all major roots and branch points. For information about the
different methods of creating a directory entry, refer to the Netscape Directory
Server Administrator’s Guide.
4. Create additional Directory Server instances and set up replication agreements
between your directory servers to ensure availability of your data.
Upgrade Process
Directory Server 6.0 supports migration from previous releases of Directory Server.
The migration process is described in Chapter 6, “Migrating From Previous
Versions.”
For information on migrating servers involved in replication agreements, refer to
the Netscape Directory Server Administrator’s Guide.
Unpacking the Software
If you have obtained Directory Server 6.0 software from the Netscape web site, you
will need to unpack it before beginning installation.
1. Create a new directory for the installation:
# mkdir ds6.0
# cd ds6.0
2. Download the product binaries file to the installation directory.
3. On UNIX, unpack the product binaries file using the following command:
# gzip -dc file_name.tar.gz | tar -xvof -
where file_name corresponds to the product binaries that you want to unpack.
On Windows NT and Windows 2000, unzip the product binaries.
Installation Privileges
On UNIX you must install as root if you choose to run the server on a port below
1024, such as the default LDAP ports: 389, and 636 (LDAP over SSL). If you choose
port numbers higher than 1024, you can install using any valid UNIX login. On
Windows NT or Windows 2000 you must run the installation as administrator.
