Claim:
A method of synchronizing Directory Servers (DSs) performing Global Attribute Uniqueness (GAU) using an Ordered Messaging Service (OMS), the method comprising: receiving, at an OMS Manager in a Directory Server that had been disconnected from a main group of Directory Servers (DSs), a leader message from an OMS End-point queue indicating communications have been restored; providing, by said OMS Manager in the DS that had been disconnected, a temporary group through which synchronization with a Leader DS in the main group will occur; sending, by said OMS Manager in the DS that had been disconnected, a sync message to the OMS group; listening, by said OMS Manager in the DS that had been disconnected, on the temporary group for sync messages; receiving, at an OMS Manager of the Leader DS, the sync message; sending, by said OMS Manager of the Leader DS, blocks of change log records as sync messages to the temporary group; receiving, by said OMS Manager in the DS that had been disconnected, the blocks of sync messages; and using, in the DS that had been disconnected, said blocks of sync messages to bring state tables and a change log into global consistency.
