LDAP Server

#install required packages
yum install openldap-servers libtool-ltdl openldap-clients openldap gnutls-bin ssl-cert

#create directory for LDIF files 
mkdir /etc/openldap/ldif
chown ldap:ldap /etc/openldap/ldif

Setup the database 

cp -a /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
