sounds like you copied the Users folder, move is (a big?) differnece from copy. i would have just moved the Users folder (holding command key down while dragging the folder in Finder) to avoid confusion. or it might be that the permissions got screwed.
someone here has mentioned that perhaps if you .sit the Users folder before moving it, that might help keep the permissions. or i think there is also a tar command (from Terminal) that will retain permissions. if you want to give it another go, i'd just use the Terminal and the mv command, and perhaps find out what that tar command is.
