To add a user or group to an ACL resource, click Add ACL User in
the ACL Manager panel. In the Add Acl User window,
enter the user or group name in the User field.
Select the boxes that correspond to the default Read, Write, Alter,
and Control permissions that you want to grant. Then click Add.
The user is added, and the ACL listing is automatically updated. You cannot delete
an individual user or group from
an ACL resource. To delete a user, you must delete the entire ACL resource, and then
add it, omitting that user.
