If you're referring to the Allow/Require Password Change options under the Authentication Settings tab for Guest Roles, as far as I can tell, that's not intended for the local guest user database. I know there is a similar feature that can be enabled in ACS for network users who are authenticated by a Windows user database, so I'm guessing this is similar.
Ultimately, the NGS does not make it possible for guest users or sponsors to change passwords. I have, however, figured out how to do it from the server's CLI. If you SSH to the guest server as root, you can run the following command:
psql -U postgres -h localhost gapdb -c "UPDATE guestusers SET password='new_password' WHERE username='username'"
Probably doesn't help you much with your situation, though...
