I've looked a bit on the internet and found this solution. I am not sure, however, is this constellation your wish
Actually, I've looked for a solution for my SSL problem with Firefox.
What ever - I found follow:
If you encounter this error: [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) in you apache error.log this means you have created a cert that is intended to be used to sign other certs, but you’re using that cert as your SSL cert. So, it depends how you create the SSL cert.But how can we solve this problem?!
