Administrators can run LDIF imports while the server is online from another remote server. The online import resembles the offline import, except that you must provide information about how to connect and authenticate to the target server. You can schedule the import of an LDIF file to occur at a particular time using the --task and --start YYYYMMDDhhmmss options of the import-ldif tool.
You can also specify email addresses for users that should be notified whenever the import process completes (regardless of success or failure, or only if the import fails). To set up SMTP notifications, see Working with the SMTP Account Status Notification Handler.
