The business group support user role must be used to allow users within a business group to see all of the machines provisioned in the business group. This is ideal for customers that require all of the users in a business group to have access to all of the systems created in the business group, for example when a team is working on the development of an application. If this is the only role that a user has been granted, then this is only able to request machines on behalf of other users and not for themselves.
