From 6ec31e98acc1457a36e07340d75510f5a4bcb02e Mon Sep 17 00:00:00 2001
From: Gary Williams <gwilliams@openldap.org>

Subject: [PATCH] No one complained, so here's the change to ldapdelete to add
 a -r switch to allow a branch of a directory tree to be removed.  The DN
 provided is searched recursively until the leaf nodes are hit, then
 everything is deleted.
