stopping direct root access howto ?


I am trying to stop the direct root access to CentoS 6 box so made sure all the line in the file /etc/securetty is commented out. Now when I try to login as root using putty I get the message Access denied but it still ask for password and once you provide the password it let you in. I know I can stop it using the sshd_config files PermitRootLogin no but I am sure I was able to stop root access just using the /etc/securetty longitme back. I am running CentOS on VMware ESxi, does it have anything to do with it? Thank you for you help.

Change these as well:
- /etc/security/access.conf:
Code:
-:ALL EXCEPT root:tty1
+ : root : cron crond nobody :0 tty1 tty2 tty3 tty4 tty5 tty6
+ : root : 127.0.0.1
- : root : ALL
- /etc/ssh/sshd_config:
Code:
PermitRootLogin no
PasswordAuthentication no
