If I interprete correctly what you say it is:
When I login as a normal user it works (fine). but if I login as root it says "login incorrect". That is as it should be. You should NOT login as root! And it is blocked to remind you that you are doing something wrong.

And for your second problem (ftp). Which ftp service is running on your system? (I have e.g. pure-ftp running via xinetd).
