Question about subtree renaming

["Philipp Foeckeler" <philipp.foeckeler@cerrotorre.de>]

Hi,

Could someone explain me please the prerequisites for subtree renames/moves
support by slapd (LDAP ModifyDN for non-leaf objects)?

Currently i use slapd 2.2.6-37.19 with bdb backend without.

What backend do i need to support subtree renames/moves?
What slapd versions could support it?
Do i need any special config for this?
I understand that Overlay salpo-refint would be a good idea, any other
overlays i should use then?


Thank you,
Philipp
