OK, reassigning.

BTW, the adduser code looks suspicious:

    my $ret = existing_user_status($new_name, $new_uid);
    if ($ret == (EXISTING_FOUND|EXISTING_SYSTEM)) {
        # a user with this name already exists; it's a problem when it's not a system user
        log_fatal( mtx("The user `%s' already exists, but is not a system user. Exiting."), $new_name );
        exit( RET_WRONG_OBJECT_PROPERTIES );
    }

Concerning the test $ret == (EXISTING_FOUND|EXISTING_SYSTEM),
if I understand correctly, if EXISTING_SYSTEM is set, this means
that this is a system user: in sub existing_user_status:

        $ret |= EXISTING_SYSTEM if \
            ($uid >= $config{"first_system_uid"} && $uid <= $config{"last_system_uid"});

However, I still don't understand the difference between the
two machines.
