A trusted user group restricts access to an agent that is enabled for trusted realm authentication. When you create a trusted user group, only members of the trusted user group can access the agent that is enabled for trusted realm authentication.
You can add new trusted users to an existing trusted user group.
In the Security Console, click Administration > Trusted Realms > Trusted User Groups > Manage Existing.
Use the search fields to find the trusted user group where you are adding users.
From the search results, click the trusted user group name.
From the context menu, click Add More.
Select the checkbox next to the trusted users that you want to add.
