Installation 

Install the packages, 

yum install openldap-servers openldap-clients

Restart from scratch / clean up 

If something goes wrong just after a french install, eventually clean up the whole db up, 

rm -rf /var/lib/ldap/*

cp DB_CONFIG.example /var/lib/ldap/DB_CONFIG

chown -R ldap:ldap /var/lib/ldap

Note for DB_CONFIG : otherwise you get this slapd log : bdb_db_open: Warning - No DB_CONFIG file found in directory /var/lib/ldap: (2) Expect poor performance for suffix dc=example,dc=com.  

Check everything is gone, 

slapcat

Configuration 

Edit the configuration, 

vi /etc/openldap/slapd.conf

Initialize the db, create an init.ldif containing this, 

dn: dc=example,dc=com

objectclass: dcObject

objectclass: organization

o: Example Company

dc: example

dn: cn=admin,dc=example,dc=com

objectclass: organizationalRole

cn: admin

Ref. http://www.openldap.org/doc/admin24/quickstart.html 

And create the db, 

slapadd -l init.ldif

Usage 

Check db's content, 

slaptest

ldapsearch -x -b 'dc=example,dc=com'

ldapsearch -x -b 'dc=example,dc=com' '(objectclass=*)'

ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts

User Interfaces
