Since you describe using ldbmcat, you must be using version 1.2.x.
However, an analogous answer probably applies to 2.x.

ldbmcat generates an ldif file in database order -- ie. no particular
order.  This means that branches and leaves are often written before
their parents, which is intolerable to ldapadd.

You must use ldif2ldbm to reload a file dumped by ldbmcat.  This also
has the advantage that createtimestamp and modifytimestamp will be
preserved.  It has the disadvantage that minimal checking is performed
during the reload.
