if you are talking about having two "duplicate" entries,
one: uid=xxxxx,<suffix>
one: nsuniqueid=nnnnnnnn+uid=xxxxx,<suffix>

these entries appear if the entry uid=xxxxx was added, simultaneously, 
on two servers. I think this can happen if a client tries to add an 
entry and if it doesn't get a response in some time retries on another 
server.
to find out which client this is you need to check on which servers the 
entries were originally added and then see which client was doing it
