After installing the connectors, plug-ins, and subcomponents, you must run the idsync resync command-line utility to bootstrap deployments with existing users. This command uses administrator-specified matching rules to do the following:
Link existing entries (for more information about linking users , see Linking Users)
Populate an empty directory with the contents of a remote directory
Bulk-synchronize attribute values (including passwords) between two existing user populations, where entries in both the Windows and Directory Server directories are uniquely identified and linked to each other
Instructions for synchronizing existing users in your deployment are provided in Chapter 10, Synchronizing Existing Users and User Groups.
