When you migrated the user, the NT4 sid that was assigned to him was added
to the new w2k user's sid history. ACLUI cracks the SID it got from the ACL
against the AD, and it is able to find the new user by the old SID, because
it also checks the sid history when attempting to crack a sid to a user.
