From 371afc47dc744ce4012f5ea00ced29653bd5869a Mon Sep 17 00:00:00 2001

Subject: s4:provision Remove LDB backend files in provision

Rather than try and remove the records in the LDB files, make the
provision remove the whole file.  This also removes the need to try
and carry forward the old ldb filenames.
