### To Edit a Node Agent Realm

You must set an authentication realm for users connecting to the node agent. Only administration users should have access to the node agent.

1. In the tree component, expand the Node Agents node.

2. Select the node agent configuration to edit.

3. Click the Authorization Realm tab.

4. On the Authorization Realm page, enter a realm.

   The default is `admin-realm`, created when you create the node agent. To use a different realm, replace the realms in all the components controlled by the domain or the components won't communicate properly.

5. In the Class Name field, specify the Java class that implements the realm.

6. Add any required properties.

   Authentication realms require provider-specific properties, which vary depending on what a particular implementation needs.
