Abstract

This document describes the OpenLDAP directory data organisation for the stoney cloud (Online) Backup service.

Data Organisation

The following chapters explain the data organisation of the stoney cloud OpenLDAP directory, in this case we looking at the (Online) Backup service.

Backup

The following LDIF shows the backup entry of the whole OpenLDAP directory tree for the stoney cloud: 

dn: ou=backup,ou=services,dc=stoney-cloud,dc=org
objectclass: organizationalUnit
objectclass: top
ou: backup

Backup Configuration

The sub tree for the configuration of the (online) backup service: 

dn: ou=configuration,ou=backup,ou=services,dc=stoney-cloud,dc=org

Backup Reseller Backup Notification Settings

The sub tree stores the notification information for the (online) backup service for the reseller Reseller Ltd. with the uid 4000000.

The idea is, that the reseller can receive notifications for a customer and reaction on the received information (for example, when the quota has been reached: 

dn: ou=notifications,uid=4000000,ou=reseller,ou=configuration,ou=backup,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: organizationalUnit
objectclass: sstNotificationObjectClass

The following table describes the different attributes:

Attribute
Existence
Mandatory
Selfcare
Changeable
 Description
uid
MUST
x
x
The unique identifier (uid). This attribute is created by the selfcare interface by reading (and incrementing) the next free uid from "cn=nextfreeuid,ou=administration,dc=stoney-cloud,dc=org".
userPassword
MAY
x
x
x
 Identifies the entry's password and encryption method in the following format: {encryption method}encrypted password. For example: {SSHA}zBiT1dHAZh/8zbCeyocRVWhdP0j9xJ3U. This password will be automatically set through the selfcare interface. Afterwords, the password can be changed by the user (including the reseller and customer).
uidNumber
MUST
x
Related to the /etc/shadow file, this attribute specifies the user's login ID. Is the same as the uid. For example: 3723707.
gidNumber
MUST
x
Group ID number. Is the same as the uid. For example: 3723707.
cn
MUST
x
givenName and Surname. Will be used for the presentation in the interface. TBD
gecos
MAY
x
x
x
 Named for historical reasons, the GECOS field is mandatory and is used to store extra information (such as the user's full name). Utilities such as finger or getent access this field to provide additional user information. For a personal account, this entry would consist of givenName and surname, for example Michael Eichenberger. These values are taken from the owners entry (ou=people). For a service account, the attribute sstDisplayName from the corresponding service would be used for the content of this attribute. Please be aware, that this attribute is a IA5String (OID=1.3.6.1.4.1.1466.115.121.1.26) IA5 (almost ASCII) character set (7-bit). Does NOT allow extended characters e.g. é, Ø, å etc. The selfcare interface automatically creates the content of this attribute. The user (including the reseller and customer) can modify this attribute as desired (except for the IA5 restrictions).

You can use:
~ $ echo "Tüpfelhyänenöhrchen" | iconv -f 'utf-8' -t 'ASCII//TRANSLIT'
which gives you:
Tuepfelhyaenenoehrchen
or:
iconv("UTF-8", "ASCII//TRANSLIT", "Tüpfelhyänenöhrchen")
Please be aware, that some characters don't get converted properly ... For example: Ø and £. The characters $ and € work.

homeDirectory
MUST
x
The directory path corresponds with the 7 digit account uid. The following example describes, how the directory structure is built up for the account with the uid 3723707.

Provisioning

Die Provisionierung benötigt die drei Attribute sstProvisioningMode und sstProvisioningState und sstProvisioningExecutionDate. Ablauf:

  1. sstProvisioningMode: Die Applikation Selfcare beschreibt das Attribut sstProvisioningMode mit den Werten add, modify der delete.
    1. sstProvisioningMode: add: Der Service soll hinzugefügt werden. Dieser Fall muss mehrmals nacheinander aufgerufen werden können. Beispiel: Bei Online Backup wurde die chroot-Umgebung bereits erstellt, dann müsste ein add nur noch kontrollieren, ob die chroot-Umgebung aktuell ist, falls nicht, müssten die entsprechenden Punkte aktualisiert werden.
    2. sstProvisioningMode: modify: Der Service soll modifiziert werden.
    3. sstProvisioningMode: delete: Der Service soll gelöscht werden.
  2. sstProvisioningExecutionDate: Die Applikation Selfcare beschreibt das Attribut sstProvisioningExecutionDate mit dem gewünschten Ausführungszeitpunkt. Zwei Fälle:
    1. 0: Dies bedeutet "sofort" und wird durch den Provisionierungs-Daemon provisioning.pl ausgewertet.
    2. [YYYY][MM][DD]: Das gewünschte Ausführungsdatum (ISO 8601). Muss mindestens ein Tag später als das aktuelle Datum sein, da diese Attribut durch ein alle 24 Stunden aufgerufenes Aufräum-Script gelesen wird. Der genaue Ausführungszeitpunkt kann somit nicht bestimmt werden (da abhängig vom Ausführungszeitpuntk der Aufräum-Scripts und der Anzahl anstehenden Aufgaben).
  3. sstProvisioningState: Die Applikation Selfcare oder der Provisionierungs-Daemon provisioning.pl beschreiben das Attribut sstProvisioningState:
    1. Keine Provisionierung nötig: Falls eine Änderung keine Provisionierung im Backend verlangt (zum Beispiel bei einer Passwört-Änderung), wird das Attribut sstProvisioningState direkt durch die Applikation Selfcare it dem aktuellen Datum und der aktuellen Zeit in Form von [YYYY][MM][DD]T[hh][mm][ss] ausfüllen (ISO 8601) beschrieben. In diesem Falle ignoriert der Provisionierungs-Daemon provisioning.pl die Modifikation.
    2. Provisionierung nötig: Falls eine Änderung eine Provisionierung im Backend verlangt (zum Beispiel bei einer Quota-Änderung), muss die Applikation Selfcare dieses Attribut auf den Wert 0 setzen. Nach der erfolgreichen Provisionierung muss Provisionierungs-Daemon provisioning.pl das Attribut sstProvisioningState mit dem aktuellen Datum und der aktuellen Zeit in Form von [YYYY][MM][DD]T[hh][mm][ss] ausfüllen (ISO 8601).

Die Applikation Selfcare darf erst dann wieder eine Modifikation durch einen Benutzer zulassen, wenn das Attribut sstProvisioningState einen gültigen Zeitstempel in der Form von [YYYY][MM][DD]T[hh][mm][ss] (ISO 8601) hat. Technisch gesehen muss der Provisionierungs-Daemon provisioning.pl im RefreshAndPersist Modus nur noch auf die LDAP-Mechanismen add und modify hören. Der LDAP-Mechanismus delete muss ignoriert werden.
