Directory catalogs are either client-based or server-based. Using a client-based condensed Directory Catalog, often referred to as a Mobile Directory Catalog, IBM® Lotus® Notes® users can access directory information for an enterprise off-line, when not connected to the network. Servers use server-based directory catalogs, either a condensed Directory Catalog or an Extended Directory Catalog, to look up information originating from a secondary Domino Directory.

Some of the questions to ask when planning directory catalogs are:

• Which documents and fields should be aggregated into a directory catalog? Which information you aggregate depends on the type and purpose of the of directory catalog.
• If your company uses multiple Domino Directories, should you set up servers to use a directory catalog? The more Domino Directories a company uses, the more benefit there is to aggregating the directories in a directory catalog used by servers. An Extended Directory Catalog, rather than a condensed Directory Catalog, is recommended for servers.
• Do you want to use a server-based directory catalog for client authentication? If so, how you enable the use of the directory catalog for this purpose depends on the type of server-based directory catalog you use.
• If you plan to use a condensed Directory Catalog, how should the entries be sorted? You should sort a Mobile Directory Catalog according to how users typically enter names when addressing mail so that type-ahead addressing can find the names.
