Hi Marlon,
I’ve little confusion. You said that you want APACHE to use 3 IS certs. Can you explain what do you mean by using 3 IS certs? Is it something Your IS public key is having chain of 3 certs? Or if in your IS you have 3 certs then what i understood is One set of certificate is for SSL handshake, second set of cert should be for sign/verify and third set of certificate should be for encryption/decryption. If this is true then you need to find out which one you are using for SSL, same should be configured to APACHE.
