openldap-2.3 on CentOS5 Tutorial

I had to get a dummy openldap setup that had “mail” as one of it’s attributes for the records. I specifically needed all the records to live in the root ou, meaning no Organizational Units, just the root, then all the records. Like this:

dn: cn=1,dc=example,dc=com
cn: 1
objectClass: top
objectClass: dkuser
mailHost: somesmtphostname1:25

dn: cn=2,dc=example,dc=com
cn: 2
objectClass: top
objectClass: dkuser
mailHost: somesmtphostname2:25

…. and so on.

It was hard to find a step by step instruction set. So, in this tutorial, I’ll give you command by command steps to install, configure and load openldap on a CentOS5 OS.

First, install the packages with Yum:

yum install openldap openldap-clients openldap-servers nss_ldap python-ldap

Next, set ldap to run at system startup time:

/sbin/chkconfig ldap on

Next, get your password for slapd.conf:

cd /etc/openldap/

…. it’ll prompt you for a new password, type it twice. All it does is spit out a password that you can copy paste into slapd. Looks like this:

New password:
Re-enter new password:
