I just tested sudo on Ubuntu with passwd authentication (not PAM) and that is how it behaves. Note that if /etc/shadow exists, sudo will use the encrypted password in it, regardless of the value of the password field in /etc/passwd. Some programs don't prompt for a password at all if the password field is empty but sudo doesn't behave that way. - todd ____________________________________________________________ sudo-users mailing list <[email protected]> For list information, options, or to unsubscribe, visit: https://www.sudo.ws/mailman/listinfo/sudo-users
