Rename your existing 10-ssl.conf to 10-ssl.conf.ext and make it  
readable by root only. Now create a new 10-ssl.conf file with the  
following content:

   # SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt>
   ssl = no

   !include_try 10-ssl.conf.ext

This will cause all non-root users to disable SSL and will only enable  
it when started as root.
