I have a multidomain and wildcard certificate by startssl.com after following the tutorial from howtoforge and it is working properly for pureftp, postfix, courier, etc. but now I am wondering how to install it for some of the sites included in it. using apache2 on a debian installation. I am not sure how the ispcfg3 SSL tab is to be used with this certificate? I saw the checkbox for ssl when editing a site, what does ticking the box do? if I check the box, how do I get apache2 to use the certificate I have? any hints?
