After install Domain Mapping and do the setup to force https on login and admin pages, the new users can't log in with the correct passwords.
1 ) With Domain Mapping enabled and using a wordpress password auto generated the login runs;
1 ) With Domain Mapping enabled and using a new password generated by user on admin page, the login not runs;
3 ) Disabling Domain Mapping, on all situation, the login runs (on https and http);
Just to inform, my initial installation of wordpress was at http and my SSL is a standard wildcard provided by GoDaddy.
