I have messed with it very thoroughly, but my /etc/security/access.conf file has -:ALL EXCEPT root:ALL I think I may have also tried it with a username after root, but don't recall now. I didn't need to restart sshd after I made the changes to the files (/etc/security/access.conf, /etc/pam.d/ssh and /etc/pam.d/login. FWIW I found the example on this page http://www.phptr.com/articles/article.asp?p=165226&seqNum=12 very helpful.
