[Zope] Changing user pwds

Hello, I created a form to allow users to change their own passwords. I hate the idea of giving them all "Manage Users" permissions, but ok whatever. But "acl_users.manage_users('Change', REQUEST, RESPONSE)" won't work unless the user has "View Management Screens" permissions. Not only does this make no sense, because the procedure doesn't involve viewing management screens, but it would be absolute insanity to give all of my users those permissions, because then they could go in and delete users at will! There has to be a way to do this, but can I get around this problem without additional products (i.e. Login Manager)? Thanks, Aaron
