Controlling how a server finds a remote primary Domino Directory to use
To locate a remote primary IBM® Lotus® Domino™ Directory, a server with a Configuration Directory can use a default logic or can use a directory replica specified through directory assistance.

The default logic to locate a remote primary Domino Directory

The Directory Servers view in a Domino Directory list the replicas of the primary Domino Directories in the domain that are available for use as remote primary directories by servers with Configuration Directories. The views sort these replicas alphabetically by their server names.

A server that stores a Configuration Directory uses the following logic to build a list in memory of the five best remote primary Domino Directory replicas to use. If the first replica in the list is unavailable, the server uses the next replica in the list, and so on.

1. Look in the replication history and find the remote primary directory replica with which the server most recently replicated. Then look for the replica with which it replicated prior to that, and so on.

2. If the list in memory does not yet include five replicas of a remote primary directory, look for a primary directory replica in the same Notes named network. If there is more than one such replica, order them alphabetically by their server names.

3. If the server has not yet located five replicas, refer to the Directory Servers view to order the remaining remote primary directory replicas alphabetically by their server names, until there are five primary directories in the list or until all the primary directories are listed.

Setting up directory assistance to locate a primary Domino Directory

You can use directory assistance rather than the default logic to control which remote primary Domino Directory replicas in a domain servers with Configuration Directories use. For example, if servers with primary Domino Directories are in a cluster, you can use directory assistance to use cluster failover to locate the primary Domino Directory replicas.

To create a Directory Assistance document in a directory assistance database that servers with Configuration Directories use:

1. Make sure you have set up a directory assistance database on servers with configuration Domino Directories.

2. From the Domino Administrator, connect to a server that is set up to use the directory assistance database.

3. Click the Configuration tab.

4. Expand Directory and select Directory Assistance.

5. Click "Add Directory Assistance."

6. On the Basics tab, do the following:

7. On the Replicas tab do one of the following: Note A server always trusts the primary Domino Directory for client authentication, so it is not necessary to enable a trusted rule in the Directory Assistance document.
