Can't speak with certainty about CentOS6 but assuming that it is using sssd somewhat like Fedora you need to concentrate on /etc/sssd/sssd.conf and include ldap_tls_reqcert = never Note that sssd essentially takes the place of padl tools (/etc/ldap.conf) Also note that /etc/openldap/ldap.conf is only for openldap cli client tools such as ldapsearch/ldapmodify/etc. That's why /root/.ldaprc sort of works for you but it is much more logical/consistent to configure sssd.conf properly because that is where daemons should be looking for system configuration information.
