I'm trying to import contacts into Zimbra from a very old copy of Lotus Notes and have one person with over 1,800 contacts.

Is there a way that I can quickly (via a CLI) delete his contacts if I screw up the import? I'm using the REST interface via a CSV file and the import goes very smoothly; but I need to be able to quickly reset his address book. The thought of selecting over 1,800 contacts via a GUI breaks my heart!

(if you can point me to where openLDAP stores the records, I might be able to hack a perl script together, but would rather not do the work if I don't have to...)
