limiting root access

[Kevin Chan]

Hi, I was wondering if it is possible for root access to be strictly 
limited to using su (i.e., not able to do ssh root@whatever or to ssh into 
a server as root from windows/mac client).  Currently we have 2 machines 
running SSH(1) on version 1.2.27.

So if anyone has an idea, please let me know.

Thanks in advance,
