Chapter 1. Red Hat Network Overview 3RHN Management is based upon the concept of an organization. Each Management-level Red Hatcustomer has the ability to establish users who have administration privileges to system groups. AnOrganization Administrator has overall control over each Red Hat Network organization with theability to add and remove systems and users. When users other than the Organization Administratorlog into the Red Hat Network website, they see only the systems they have permission to administer.To create an account that can be used to entitle systems to RHN Management, go tohttps://rhn.redhat.com/ and click on the Create Account link under the Sign In fields. On the SignUp for Red Hat Network page, click Create a new Corporate Login.
