When a modrdn operation is done on a subtree (I.e., subtree rename), the result
is that back-hdb will return certain entries in that subtree multiple times. 
Stopping and restarting slapd fixes the behavior.

Example:

ldapsearch -x -v -H 'ldap://HOST '  -w PASSWORD  -D
'uid=zimbra,cn=admins,cn=zimbra'  -b "dc=NEWDOMAIN,dc=COM"
ldap_initialize( ldap://HOST:389/??base )
filter: (objectclass=*)
requesting: All userApplication attributes
# extended LDIF
#
# LDAPv3
# base <dc=NEWDOMAIN,dc=COM> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#
