This is now fixed in git master. For the record, it had nothing to do with 
modrdn; it was a bug in the back-hdb subtree IDL code, and would always occur 
if IDL caching was enabled, and a subtree below the search target was searched 
before the search target. It could be easily duplicated in the test suite 
using e.g.
	ldapsearch -b "ou=alumni association,ou=people,dc=example,dc=com"
	ldapsearch -b ou=people,dc=example,dc=com
which would result in "ou=alumni association" being returned twice on the 2nd 
search.
