I have a need to secure a portion of a site - the "admin" control panel. I need to use client certificates to secure the sub domain. So that anyone that goes to the site without the certificate installed in their browser will be dumped by apache. Is this possible to do with a stock DA install? If not (which Im sure will be the case), any one got any suggestions. Ive tried a few things but with no luck and dont want to start coding something thats already been done. Any help would be appreciated.
