Central Configuration

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

Go to the Admin portal.
Click Advanced > Central Config.
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.
