This document describes the set-up of the OpenLDAP directory of the stoney cloud. This directory contains the data of services [[:Category:Self-Service Modules|Self-Service Modules]] (modulesservices) like [[Selfcare:Category:stoney core|stoney core]], [[:Category:stoney conductor|stoney conductor]], [[Virtualization:Category:stoney vm|stoney vm]], [[Online Backup:Category:stoney backup|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 Oct 2 14:49:49 stoney-cloud-node-02 slapd[15192]: slapd starting ps auxf | grep slapd ldap 15192 0.0 0.0 324516 21468 ?

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-hdb === cd /root time ldapsearch -H ldaps://ldapm.stoney-cloud.org -b "ou=services,dc=stoney-cloud,dc=org" -s sub -x -D "cn=Manager,dc=stoney-cloud,dc=org" "(objectclass=*)" -v -w admin > gugus.ldif ldap_initialize( ldaps://ldapm.stoney-cloud.org:636/??base ) filter: (objectclass=*) requesting: All userApplication attributes real 0m0.029s user 0m0.010s sys 0m0.000s Size of the database with all the indices: du -h /var/lib/openldap-hdb/foss-cloud 5.2M /var/lib/openldap-hdb/foss-cloud cd /var/lib/openldap-hdb/foss-cloud ls -alh<pre>total 5.2Mdrwx------ 2 ldap ldap 4.0K 6.
