It should. One problem of that function is it is not transactional.
This means that a failure between a certain set of operations will
leave the dn and the index spaces in a dangling state. I've been
working on that for a while, but as the problem will be outdated
by back-bdb and modrdn should be considered an administrative 
operation, to be performed with extra care, I didn't go too deep 
into it. Can you detail to what extent the multiple instances of
the entry coexist? I mean, do they show up when looking for 
a(n indexed) value they share or when dumping (ldapsearch or slapcat) 
the db?
