Abstract
In a computer network having a plurality of computer nodes, a directory database (DDB) distributed throughout the network in each of the nodes, the contents of the DDB being maintained consistent or replicated throughout the network through the use of one of its nodes having been appointed as master node. The master node has a privileged status as compared to the other nodes. The master node updates each DDB in each node in its network or domain configuration when the configuration changes. A global administrator is a privileged user compared to other computer network users who has authority to replace or select a master node and to configure a domain, and who performs these and other functions by way of computer terminal screen dialogs offered by a graphical user interface (GUI) associated with the computer network. Only one master node per domain is permitted and if the password-protected global administrator's security is breached, other users may select other master nodes for the same network resulting in master to master conflict. In the case of multiple master nodes attempting to be master for the same nodes in the same network at the same time, this conflict is resolved in o…
