Systems and methods according to the present invention may include providing a first directory service program, a second directory service program, and a directory service access program for handling client application information requests. The directory service access program may direct and manage the client application information requests to either the first directory service program if the requested information is associated with the first directory service program or the second directory service program if requested information is associated with the second directory service program. The present invention may also include providing a data service synchronizer that replicates certain information from the first directory service program to the second directory service program; monitors the first directory service program for changes; and updates the second directory service program with changes from the first directory service program such that the first and second directory service programs may interoperate with one another.

Systems and methods for interoperation of directory services

A data management system with data stored in multiple disparate formats in synchronized stores, method of synchronizing the data and recovering from synchronization failures and program product therefor. Data changes in one data store are cached in a universal format in an active synchronizer and forwarded to a second store from the universal format cache. Standby synchronizers provide failover handling by identifying synchronization failures and self-selecting a replacement synchronizer to serve as the active synchronizer.
