As you can see in Figure 10.13, the resulting dialog box allows you to view, add, and remove list members. Clearing Existing Permissions In the previous section, I mentioned that you can't add a security group to the Power Users list if you have previously assigned permissions to the group. You can, however, get rid of the permissions that you assigned manually, and then add the group to the Power Users list. To clear out permissions that you have manually assigned, follow these steps: 1. Select the Security container for the protection policy that you are working with. The Security container will show the existing permissions for each device, as shown in Figure 10.14. 2. Click the Switch to Users View link, located in the Common Tasks section. 3. The user's view will show each security group and the permissions that have been assigned to it, as shown in Figure 10.15. Right-click on the group that you want to remove, and select the Delete Permissions command from the resulting shortcut menu.
