Central Configuration

Central Configuration

The Central Configuration is where all global settings for a Domino installation are listed.

  1. Go to the Admin portal.

  2. Click Advanced > Central Config.

  3. On the Configuration Management page, you can:

    • Click an existing record to edit its attributes.

    • Click Add Record to create a new setting. If no record is created in the application, the system uses the default value.

      You must restart the Domino services for changes to take effect. To do this, click here to restart services.

Authentication

These options relate to the Keycloak authentication service. They are available in namespace common and must be recorded with no name.

Key

Default

Description

authentication.oidc.externalOrgsEnabled

false
