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 in a manner to avoid a single point of failure 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.
