I'm not an openca expert, so you'll hate me, look, I don't bring a solution per se, mostly because it doesn't match your language. Here in my country we have a university server with an openca tutorial, unfortunately for you, in spanish:
http://www.uco.es/ccc/sistemas/doc_c...A/install.html
I just suggest this until anyone else can help you better, when I need to read something in some strange language (like english to me, *hah) I use one firefox translator, foxlingo, and works pretty well.
Another argentinian tutorial, in spanish, and newer, for debian (you didn't say you distro):

Hope it helps in some remote way.
