= Abstract =
This document describes the OpenLDAP directory data organisation for the [[Main_Page | stoney cloud]]. This directory is the database for all the services. Each service has its own [[:Category:Modules|module]], which normally consists of:
* An OpenLDAP directory service entry, which contains all the relevant data like main configuration, default settings and the service entries.
* The web interface section, which hooks itself into the [[:Category:stoney core|stoney core]] main framework.
* Finally, a provisioning daemon, which is responsible for adding, modifying and deleting the actual service on the different back-end systems.
= Introduction =
All Service-, User- and Billing-Data are stored in the [http://www.openldap.org/ OpenLDAP] directory. The OpenLDAP directory runs in Multi-Master Mirror-Mode for high availability.
= Data Organisation =
The following chapters explain the data organisation of the stoney cloud OpenLDAP directory.
== root ==
The following LDIF shows the '''root''' entry of the whole OpenLDAP directory tree for the stoney cloud:
dn: dc=stoney-cloud,dc=org
objectclass: top
objectclass: dcObject
objectclass: organization
dc: stoney-cloud
o: stoney-cloud
The following LDIF shows the root of the whole OpenLDAP directory tree for the stoney cloud modified for the company stepping stone GmbH in Switzerland:
dn: o=stepping-stone,c=ch
objectclass: top
objectclass: organization
o: stepping-stone
The entry '''c=ch''' stands for the country code of Switzerland while '''o=stepping-stone''' stands for the the organisation stepping-stone. The entry stepping-stone is in the process of being reserved at the [http://www.bakom.admin.ch/index.html?lang=en Federal Office of Communications]. With the reservation of the name, all the directory entries will be unique over the whole world.
The '''root''' entry can be chosen during the installation process of the stoney cloud. If you decide to use the default entry, you'll end up with '''dc=stoney-cloud,dc=org'''.
== Core ==
[[:Category:stoney core|stoney core]] is the main framework responsible for shared functionality (also called self-care):
* User management, rights and roles.
* A consistent look and feel between modules.
* Internationalization.
== Services ==
The sub tree '''ou=services,dc=stoney-cloud,dc=org''' contains all the stoney cloud services like backup or mail.
dn: ou=services,dc=stone-cloud,dc=org
objectclass: organizationalUnit
objectclass: top
ou: services
The actual services are described in the following chapters.
=== Backup ===
The (Online) Backup service consists of two areas:
* '''Server''': The actual backup space with some extra functionality like informing the user when the backup space runs full or if a back was not executed at the planned time.
* '''Client''': The backup client (for example [http://www.sepiola.org/en/ Sepiola]), which is responsible to regularly copy the local data to the backup server.
On the back server the data copied to the backup space ist compared each day to the previous day's backup. If there are any changes found, a copy of the data will be made (a snapshot taken). Thus the user has access to 7 daily, 4 weekly and 3 monthly backups. During each snapshot, only the modified data is copied - thereby making optimal use of the available disk space.
This OpenLDAP related section of the Backup service is described on the [[Backup (OpenLDAP)]] page.
