Digging a bit deeper into this, I found that only back-hdb is affected and
that it is most probably a bug in hdb_dn2id_add(). It seems that after adding
a new entry, hdb_dn2id_add() fails to correctly update the IDLs in the idl-
cache for the entry's parent entries.
The following patch seems to fix the problem for me:

I suspect that hdb_dn2id_delete() has a similar issue.
