+    ldap handler has new options: backup method to use (ldapsearch or

+    is set to ldapsearch as this is safer

 ## compress (default yes): if set to yes, ldif exports are gzipped.

+## restart (default no): if set to yes, slapd is restarted before backups are

+## method (default ldapsearch): either 'ldapsearch' or 'slapcat'

+## passwordfile (no default): this should be set to the file that contains 
+## your ldap password, this is required for ldapsearch and not needed for slapcat
+## this file should have no newlines in it, echo -n "password" > passfile works.
