Abstract
This document describes the set-up of the OpenLDAP directory of the stoney cloud. This directory contains the data of Self-Service Modules (services) like stoney core, stoney conductor, stoney vm, stoney backup and more.
Directory set-up
Indices
If you see entries similar to the following entry, you need to add indices to your slapd.conf configuration file:
grep bdb_equality_candidates /var/log/syslog/slapd.log
Oct 2 13:39:19 stoney-cloud-node-01 slapd[19508]: <= bdb_equality_candidates: (dhcpHWAddress) not indexed
Adding an index
Adding an index to your slapd.conf configuration file:
vi /etc/openldap/slapd.conf
index dhcpHWAddress eq
Now stop the OpenLDAP daemon:
/etc/init.d/slapd stop
Rebuild all you indices (works well for small directories):
slapindex -f /etc/openldap/slapd.conf
Set the proper permissions:
chown ldap:ldap /var/lib/openldap-hdb/foss-cloud/* chmod 700 /var/lib/openldap-hdb/foss-cloud/*
Now start the OpenLDAP daemon:
/etc/init.d/slapd start
Make sure, that the OpenLDAP daemon started cleanly:
tail -f /var/log/syslog/slapd.log
Oct 2 14:49:49 stoney-cloud-node-02 slapd[15191]: @(#) $OpenLDAP: slapd 2.4.30 (Feb 4 2013 16:01:35) $
@kvm-060:/var/tmp/portage/net-nds/openldap-2.4.30/work/openldap-2.4.30/servers/slapd

Backends
The mdb backend to slapd(8) is the upcoming primary backend for a normal slapd database. It uses OpenLDAP's own Lightning Memory-Mapped Database (LMDB) library to store data and is intended to replace the Berkeley DB backends.
It supports indexing like the BDB backends, but it uses no caching and requires no tuning to deliver maximum search performance. Like hdb, it is also fully hierarchical and supports subtree renames in constant time.

slapd-mdb
The mdb backend to slapd(8) is the upcoming primary backend for a normal slapd database. It uses OpenLDAP's own Lightning Memory-Mapped Database (LMDB) library to store data and is intended to replace the Berkeley DB backends.
It supports indexing like the BDB backends, but it uses no caching and requires no tuning to deliver maximum search performance. Like hdb, it is also fully hierarchical and supports subtree renames in constant time.
