Red Hat Directory Server 8.0 Administrator's Guide

The LDAP tools referenced in this guide are Mozilla LDAP, installed with Directory Server in the

/usr/lib/mozldap directory on Red Hat Enterprise Linux 5 i386; directories for other platforms are listed in

Section 2, “LDAP Tool Locations”. However, Red Hat Enterprise Linux systems also include LDAP tools from

OpenLDAP. It is possible to use the OpenLDAP commands as shown in the examples, but you must use the -x

argument to disable SASL and allow simple authentication.

cn=plugins,cn=config entry.

• To create a new index for a particular database, add it to the

cn=index,cn=database_name,cn=ldbm database,cn=plugins,cn=config entry, where

cn=database_name corresponds to the name of the database.

NOTE

Avoid creating entries under cn=config in the dse.ldif file. The cn=config

entry in the simple, flat dse.ldif configuration file is not stored in the same

highly scalable database as regular entries. As a result, if many entries,

particularly entries that are likely to be updated frequently, are stored under

cn=config, performance will probably suffer. Although we recommend you do

not store simple user entries under cn=config for performance reasons, it can

be useful to store special user entries such as the Directory Manager entry or

replication manager (supplier bind DN) entry under cn=config since this

centralizes configuration information.

For information on the LDIF update statements required to add entries, see Section 4, “LDIF

Update Statements”.

For example, to create presence, equality, and substring indexes for the sn (surname) attribute

in the Example1 database, do the following:

1. Open the Directory Server LDAP tool directory.

cd /usr/lib/mozldap

2. Run ldapmodify.

ldapmodify -a -h server -p 389 -D "cn=directory manager" -w password

The ldapmodify utility binds to the server and prepares it to add an entry to the configuration

file.

3. Add the LDIF entry for the new indexes:

dn: cn=sn,cn=index,cn=Example1,cn=ldbm database,cn=plugins,cn=config
