Controlling how a server finds a remote primary Domino® Directory

The IBM® Domino® server uses default settings or directory assistance to locate a remote primary Domino® Directory.

About this task

To locate a remote primaryDomino Directory, a server with a Configuration Directory can use a default logic or can use a directory replica specified through directory assistance.

Using defaults

About this task

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.

Procedure

  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 IBM® 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.

Using directory assistance

About this task

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:
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.

Procedure

  1. Make sure you have set up servers with configuration Domino® Directories to use directory assistance databases.
  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:
    1. Next to Domain Type, select Notes.
    2. Next to Domain Name, enter the domain of the servers that store the remote primary Domino® Directories. This domain should be the same domain as that of the servers with configuration Domino® Directories.
    3. Next to Search Order, select 1.
    4. Next to Group Authorization, select No. A server can always use groups in a primary Domino® Directory replica to authorize database access, regardless of what you select for this option. You select No to reserve the use of the Group Authorization option for a secondary directory.
  7. On the Replicas tab do one of the following:
    • If the servers that store the primary Domino® Directories are clustered, specify only one replica within the cluster to user cluster failover. If that replica is unavailable, cluster failover takes effect automatically.
    • If the servers that store primary Domino® Directories are not clustered, specify at least two replicas of the primary Domino® Directories to use for failover.
