11.6 Directory services<br />

There are several aspects of Domino directory services that should be<br />

considered in securing any Domino environment.<br />

11.6.1 Directory administration servers<br />

Each Domino domain has at least one administration server for the Domino<br />

Directory. The administration server is responsible for carrying out Administration<br />

Process requests that automate changes to the Domino Directory. By default,<br />

the first server set up in a domain is the administration server for the Domino<br />

Directory.<br />

11.6.2 Dedicated directory servers<br />

You can use directory servers in a Domino domain to dedicate specific servers to<br />

providing directory services. Clients and specialized servers such as mail and<br />

application servers use the directory servers to look up user, group, and similar<br />

information.<br />

A directory server might:<br />

► In a central directory architecture, store a primary Domino Directory that<br />

servers with Configuration Directories access remotely<br />

► Run the LDAP service<br />

► Run the Dircat task to build and store directory catalogs<br />

► Store replicas of directories that are aggregated into the directory catalog<br />

► Store replicas of secondary Domino Directories that servers in the domain<br />

access through directory assistance<br />

You can set up Notes clients to use directory servers, rather than their mail<br />

servers, to look up names and addresses.<br />
