We should find a way to handle subobjects
In some cases, a node might be moved which contain other objects. As we cannot search for any object under a node we move for performance reasons, maybe we should add an information like «this objectType might contain these other objectTypes under it», or «this objectType might be stored under this other objectType», which would allow for precise ldap search to detect such cases.
The first thing to do is still to list such cases to make sure we do not do this for nothing.
(the idea is to handle foreignkey on the subnodes when moving a subtree)
