By default, one-X Portal for IP Office servers use Referred Authentication. That means that the portal administration rights are assigned to security users configured in the security configuration of the IP Office service running on the same server. By default that is the Administrator user, however additional service users can also be configured for portal administrator access.

If referred authentication is disabled, the portal uses its own local administrator account, stored in the portal's own settings (or Superuser for the AFA menus).
