When moving a node with subnodes, like a departement, this will use a
 filter like member=* to get references, meaning it will open all groups
 and roles and other objects which may reference DNs to make sure the
 foreign key is applied and the new DN is stored.
This will be slow if there are a lot of those objects.
Impacted fields are member, manager, roleOccupant and owner.
This is needed because they do not allow SUBSTR searches by schema
 definition.
