 I just realised that pam_access no longer works under CentOS6 - or it works
 differently from CentOS5.

 Under CentOS5, I used this configuration to restrict access to root only:

# cat /etc/security/access.conf
+ : root : ALL
- : ALL : ALL
# cat /etc/pam.d/system-auth-ac
account     required      pam_access.so
account     required      pam_unix.so
account     sufficient    pam_localuser.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     required      pam_permit.so

 Under CentOS6, this has no effect and I can still login as non-root user.
 What am I missing?
