Abstract
A domain controller hierarchy includes one or more hub domain controllers in communication with one or more local domain controllers, such as local domain controllers at a branch office. The hub domain controller(s) is writable, while the local domain controller(s) is typically read-only. Non-secure and secure information is partitioned to specific local domain controllers at the one or more hub domain controllers. The non-secure and secure information is then passed from the hub domain controller only to the local domain controller associated with the given partition at the hub domain controller on request. For example, a user requests a logon at a client computer system at a local branch office, and the logon is passed from the local domain controller to the hub domain controller. If authenticated, the user logon account is passed to the local domain controller, where it can be cached to authenticate subsequent requests.
