-Ideally you'll be using this against an empty LDAP directory.  You can use the setup utility to create the LDAP structures that this tool needs in order to create accounts and groups.   Go to https://_website-hostname_/setup to get started.   You need to log in with the password for the admin user as set by `LDAP_ADMIN_BIND_DN`.

 The setup utility will create the user and account trees, records that store the last UID and GID used when creating a user account or group, a group for admins and the initial admin account.
