Configuring
Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
Configuring directory services
This section describes how to plan, set up, and use IBM® Domino® directory services.
Directory catalogs
A directory catalog is an optional directory database that typically contains information aggregated from multiple Domino® directories. Clients and servers can use a directory catalog to look up mail addresses and other information about the people, groups, mail-in databases, and resources throughout an organization, regardless of the number of Domino domains and Domino Directories the organization uses.
Planning issues specific to extended directory catalogs
Consider the issues in the related topics when planning an extended directory catalog.
Extended directory catalog size
Because the extended directory catalog contains the views that are in a standard Domino® Directory and combines multiple Domino directories into one database, it typically is very large. If you aggregate all fields as recommended, an extended directory catalog is about the size of all the aggregated Domino directories combined. Do not replicate the database to Notes® clients, and use as few replicas on servers as feasible.
