#### To Set the Default Realm

The default realm is the realm that the Application Server uses for authentication and authorization if an application’s deployment descriptor does not specify a realm.

1. Expand the Configurations node.
2. In the Cluster and Enterprise profile, select the instance to configure:
   - To configure a particular instance, expand the instance’s config node. For example, the default instance, `server`, expand the `server-config` node.
   - To configure the default settings for all instances, expand the `default-config` node.
3. Select the Security node.

   The Security page displays.

4. In the Default Realm field, pick the desired realm from the drop-down list.
5. Click Save to save the changes.
6. Restart the server if Restart Required displays in the console.
