An administrator's privileges are scoped by the organization to which the administrator authenticates.
The vCloud API defines two levels of administrative privilege:
Some administrative operations, and all vSphere platform operations, are restricted to the system administrator. Before you attempt these operations, log in to the System organization with the user name and password of the system administrator account that was created when vCloud Director was installed, or the user name and password of any member of the System organization. For example, a system administrator whose user name was defined as administrator would log in as administrator@System.
The System organization is created automatically when vCloud Director is installed. Unlike the organizations represented by Org and AdminOrg objects, the System organization cannot contain catalogs, VDCs, groups, or users who are not system administrators.
The System organization is initially configured with one member, a local user defined as part of the vCloud Director setup process. Like all organizations, the System organization is created with implicit support for the vCloud Director integrated identity provider. A system administrator can reconfigure the System organization to use any of the other identity providers supported by vCloud Director.
When a system administrator logs in to the vCloud API, the OrgList in the returned Session element contains a link to the System organization.
<OrgList ... > ... <Org type="application/vnd.vmware.admin.systemOrganization+xml" name="System" href="https://vcloud.example.com/api/admin/org/123"/> ... </OrgList>
