GroupWise accounts are administered through eDirectory. Driver customizations are usually done in the Subscriber channel or at the driver level. The Subscriber channel receives commands from the Metadirectory engine and executes those commands in GroupWise. The Subscriber channel is used to synchronize eDirectory events with GroupWise. It watches for additions, modifications, renames, moves, and deletes in eDirectory and creates events in GroupWise to reflect those changes.
You can add to the base configuration that comes with the driver. However, do not remove or modify preconfigured attributes from the Subscriber filter or the Mapping policy.
