[Zope] LoginManager in 2.3

All, Has anyone managed to get LoginManager working in 2.3 as the 'root' acl_users. It works fine in a folder, no errors etc, but when I come to move it to the root, I get all the right prompts of old, but at the moment of pasting it I am told that the emergency user can't own objects. OK fair enough, I understand the decision made, but has anyone got a recipe for moving a LoginManager to the root? tia Phil
