Utilisation de serveurs d'annuaire dans un domaine Domino ®
Un domaine HCL Domino ® est un réseau de clients et de serveurs dont les utilisateurs, les serveurs, les connexions et les informations de contrôle d'accès sont décrits dans une base de données unique appelée Annuaire Domino ® . Lorsque vous configurez le premier serveur d'une organisation, Domino ® crée un domaine Domino ® et un annuaire Domino ® pour le domaine. Lorsque vous ajoutez des serveurs au domaine, ils extraient des répliques de l'annuaire Domino® . Pour créer un domaine supplémentaire et un annuaire Domino ® supplémentaire, vous effectuez une première configuration de serveur.

Each Domino® domain has at least one administration server for the Domino® Directory. The administration server is responsible for carrying out Administration Process requests that automate changes to the Domino® Directory. By default, the first server set up in a domain is the administration server for the Domino® Directory.
You can use directory servers in a Domino® domain to dedicate specific servers to providing directory services. Clients and specialized servers such as mail and application servers use the directory servers to look up user, group and similar information.
Un serveur d'annuaire peut :
- In a central directory architecture, store a primary Domino® Directory that servers with Configuration Directories access remotely
- exécuter le service LDAP ;
- exécuter la tâche Dircat pour créer et enregistrer des catalogues d'annuaires ;
- enregistrer des répliques d'annuaires regroupées dans le catalogue d'annuaires ;
- Store replicas of secondary Domino® Directories that servers in the domain access through directory assistance
Vous pouvez configurer les clients HCL Notes ® pour qu'ils utilisent des serveurs d'annuaire, plutôt que leurs serveurs de messagerie, pour rechercher des noms et des adresses.
Using a central directory architecture in a Domino® domain
Pour savoir comment configurer cette fonction, voir les sujets suivants :
Prior to this release, companies always used a distributed directory architecture in which every server in a Domino® domain had a full replica of the domain's primary Domino® Directory. A primary directory contains all types of documents: documents used to provide directory services such as Person and Group documents as well as documents used to configure Domino® servers.
In this release, companies can implement a central directory architecture. In a central directory architecture, a few directory servers in a domain have a replica of a the primary Domino® Directory that contains the entire contents of the Domino® Directory. The other servers in the domain have a Configuration Directory, a small, selective replica of the Domino® Directory that contains only documents used for Domino® configuration. A server with a Configuration Directory uses a primary Domino® Directory on another server -- referred to as a remote primary Domino® Directory -- to look up information in Person, Group, Mail-In Database, and Resource documents, and in any new types of custom documents a company has added to the directory.
Enterprise companies that use centralized architectures can benefit from this feature. A central directory architecture allows for tighter administrative control over directory management because only a few directory replicas contain user and group information. In addition, application and mail servers can run on less powerful machines then the directory servers require, since the application and mail servers don't have to store a primary Domino® Directory, which can be the largest database in a company. If the user and group information in a directory changes frequently, the servers with Configuration Directories have immediate access to the changes that critical business applications and processes require, because they don't have to wait for the changes to replicate locally.
To use a central directory architecture you must have adequate network bandwidth to support the remote primary directory lookups. For failover, it is also important that at least two servers in a domain are configured as a remote primary Domino® Directory.
