User cannot change the password

I installed “WordPress MU Domain Mapping” plugin on WordPress MU. Everything works good except changing the password.
When user logged in and tries to change the password he logged out.
Actually the password is changed successfully, but user cannot login again with new password.
User could login with new password in another browser or after deleting all cookies.

Can this be fixed in future?
Thank you.
