LEDName - Do not use server based directory
catalog (from Ken Lin)
A directory catalog is an
optional directory database that typically contains information aggregated
from multiple Domino Directories. A directory catalog includes the type
of information that is important for directory services, and excludes other
types of information that are part of a Domino Directory, for example Domino
configuration information, such as information in Connection documents.
A condensed Directory Catalog is created from the Directory Catalog template
(DIRCAT5.NTF). Condensed Directory Catalogs are designed to be small enough
to fit on Notes clients. For example, several Domino directories that together
contain more than 350,000 users and total 3GB in size, when aggregated
in a condensed Directory Catalog are likely to be only about 50MB. To achieve
its small size, a condensed Directory Catalog uses a unique design that
combines multiple documents from the Domino Directories into single documents
in the directory catalog, and that limits the number of sorted views available
for lookups. In support of this design, a condensed Directory Catalog relies
on FT Search to locate users or groups.
An FT search operation is expensive and thus can decrease the performance
of your server. As a result condensed Directory Catalogs are designed for
use on Notes clients.
No condensed directory catalog is used
Use a normal Domino directory
or one which is an extended Directory Catalog (a derivative of pubnames.ntf).
Changing this setting requires a restart
of the server.
