The problem occurs inside


basically because an attempt to retrieve
"cn=ldapsync," fails;  This strange DN is
caused by calling build_new_dn() with
"cn=ldapsync" and "" as parent instead of
NULL, which is the value expected by
build_new_dn() for "" based DNs.
However, letting build_new_dn() return
"cn=ldapsync" doesn't cure the problem,
because bdb_csn_commit() also fails with
the DN (there's no crash until someone
searches the database, and even curing
this second crash in bdb_do_search()
doesn't fix the problem.  I got lost
after that because I don't know enough
about the csn stuff in back-bdb.  Hope
someone else takes over this, or we
disable empty suffix for back-bdb at the
