Auto-populated groups - IBM Lotus Notes

The management of policies and distribution lists based on the users located on a server has always been an effective management tool. Unfortunately, the process of managing the group membership has been a manual task. Typically, the administration team updates the group membership list during the user registration and deletion process. The new auto-populated group feature allows updating of group membership when the update task is run on the Domino server. The resulting groups allow the administration team to effectively apply policies to the users who use the mail server as their home server.

The process of administering the auto-populated groups feature requires the configuration of the Directory Profile and the individual group properties. The Domino Group Profile can be accessed by opening the Lotus Domino Directory in either the Notes or the Administrative client. Go to Actions | Edit Directory Profile and you will get the following screen:

Auto-populated groups

Set the Auto-populated group Members update interval option to the appropriate setting for the environment; the default setting is 30 minutes. After setting the configuration, click Save & Close to confirm the new setting:

click Save

The next step is to configure the groups that will leverage the auto-population feature. In the Groups section of the Domino Directory, click on Add Group to begin the configuration:

configure the groups

It is important to set the Auto Populate Method option to Home Server and list the appropriate server in the Home Server field. After configuring the group, click on Save & Close to create the new group. The new group membership will be populated based on the users listed as utilizing the specified home server, including the member specified in the Additional Members field and excluding the members specified in the Excluded Members field. The auto-populated list cannot be manually changed; therefore, it is important to manage the inclusion and exclusion of members through the Group document. If the group grows too large, the Auto-populate feature will create subgroups and populate them through the Domino server task.

If the number of users is too large for the NameLookup process to complete, the updating of the group membership will not occur. In the event that Domino Domain Monitoring is currently being leveraged in the environment, the following error may be identified if the group membership exceeds the NameLookup threshold for the server:

Search for auto-populated group members failed for group MailServer01: NAMELookups are limited on this server to a size smaller than what would be returned. See your Domino Administrator for more information.

The administration team for the environment will be required to increase the threshold for NameLookups by configuring the notes.ini setting—Namelookup_ max_mb=1. It is recommended to replace the 1 with a larger value starting at 2 and adjusting appropriately for your environment.

Please refer to the Domino 8.5 Administration Help documentation for more current information on this feature.


Reducing the impact of the Domino server environment in terms of bandwidth has been greatly enhanced through the support of GNU Zip (Gzip) technology that was introduced for the Domino Web Server in version 8.5. This support will effectively allow for the leveraging of Gzip technology within the content stored on the Domino Web Server. It is important to understand the configuration requirements for leveraging the Gzip technology when deploying it within Domino Web Server content. The following are examples of configuration requirements, as noted in the Domino 8.5 Administration Help Database.

  • The notes.ini file must not contain the following setting: HTTPDisablePreCompressedGzipFiles=1.
  • The name of the compressed file is the name of the original file with an additional extension of .gz. For example, the gzip counterpart of c:notes data domino html foo.html is c:notes data domino html foo.html.
  • The original file must be present in the same directory as the .gz file. The original file is served if it is newer than the .gz file or compression is disabled.
