Configuring
This section provides information on configuring the servers for HCL Sametime 11.6.
Community Services
This section will discuss configuration steps specific to the HCL Sametime Community server.
Configuring LDAP
Sametime has support for LDAP and native Domino directory servers to provide the user repository. When installing Sametime, you are given an option to choose which type of directory to use. Sametime supports one directory type (LDAP or Domino directory) to be configured on the server. All Sametime Community servers must share the same directories and directory type.
Configuring the LDAP server Document
In previous releases of Sametime, there was a separate Administration client to configure LDAP settings. These settings are now done directly inside of the configuration database that holds the settings.
Defining the ID attribute for Active Directory
If your Sametime® servers connect to an Active Directory (LDAP) server and you prefer to use the DN attribute rather than the objectGUID attribute for the Sametime internal user ID, you must assign the DistinguishedName attribute to be the internal ID for Sametime users. Doing so guarantees that Active Directory returns the DN attribute in the same case-sensitive and space-sensitive format. Forcing Sametime to use a consistent attribute for the internal user ID prevents awareness problems caused by ambiguous internal user IDs.

      - Excluding certain domains from user and group directory lookups
        When you use Inbox awareness, you can prevent redundant requests to the LDAP or Domino® directory by defining which domains are allowed to accept resolve requests. Previous releases allowed this filtering through the use of custom code and was available only for LDAP directories.
      - Creating custom Java classes for searching LDAP
        Create custom Java™ classes that provide greater control over how the Sametime® Community server conducts name searches of an LDAP directory and how results are formatted.
    - Configuring Domino Directory
    - Updating time-to-live index for persistent chat
      The time-to-live (TTL) setting in the sametime.ini defines how long the chat history is stored in the database. The default value is 90 days. Administrators can modify the value based on the organization's preferred setting.

      Review the host names and ports for Community Services on the HCL Sametime Community Server.
    - Setting the same community ID for all servers in the environment
      To ensure that clients recognize all servers in the environment as belonging to a single community, add a ST_COMMUNITY_ID value to the sametime.ini file.

Defining the ID attribute for Active Directory

If your Sametime® servers connect to an Active Directory (LDAP) server and you prefer to use the DN attribute rather than the objectGUID attribute for the Sametime internal user ID, you must assign the DistinguishedName attribute to be the internal ID for Sametime users. Doing so guarantees that Active Directory returns the DN attribute in the same case-sensitive and space-sensitive format. Forcing Sametime to use a consistent attribute for the internal user ID prevents awareness problems caused by ambiguous internal user IDs.

About this task

If you choose the DN attribute for the Sametime internal user ID, but do not assign the DistinguishedName attribute as the internal ID, you may see the following problems:

Awareness for some users does not work.
A user's name appears multiple times in the same Contact list.
Policies might not be applied, so the user might receive only default policies.

Note: You can assign the objectGUID attribute as the internal user ID to eliminate the need to run the name change tool in the future.

Procedure

Launch the HCL Notes or Administration client, as the administrator.
Click on Open > Applications > Open an application.
In the servername field, enter the hostname of the Sametime server.
In the filename field, enter “stconfig.nsf”.
Scroll to the LDAPServer document and double-click to open it.
Place the document in edit mode by double-clicking inside the document.
In the field name “The attribute of the person entry that defines the internal ID of a Sametime user” enter “DistinguishedName”.
Click File > Save to save the document.
Restart the Community server for the change to take effect.
