An Identity Manager installation on a server synchronizes only the information that is contained physically in the host eDirectory server's partition replicas. This may necessitate aggregating several partitions onto a single server if a tree-wide view of eDirectory data is desired for a particular synchronization application. For more information, see Replicating the Objects that Identity Manager Needs on the Server.
The Driverset object must exist in a full read/write replica on the server that is hosting the drivers.
The Driver object must be granted sufficient eDirectory rights to any objects it is to synchronize, or the Driver object must be made security equivalent to an object that has the desired rights.
