Persistent user groups on servers managed by central servers

In a client server network comprised of a central server, a plurality of managed servers at least some of which managed servers are non-native with respect to said central server, and in which network user group records are established and are updated on said central server, a method for synchronization of user group records on managed servers in said network with user group records on said central server, including the steps of:

• sending a status update pulse from the central server to managed servers on the network;
• sending, in response to said status update pulse, a return request from a non-native managed server to the central server for update records;
• sending, in response to said return request, from said central server to said non-native managed server, an update records request or a request for full synchronization;
• defining at the non-native managed server a set of user records locally on the non-native managed server to be persistent accounts on this non-native managed server;
• excluding at the non-native managed server from potential changes on the non-native managed server, as a result of a central server full synchronization request, those user records that have been defined as persistent accounts.
