Installing a Wildcard Certificate in STRUST

Hi,

I am trying to install a wildcard SSL certificate using STRUST on our ABAP system.

If I try to import it using the "Import Cert. Response" button, I get an error message saying the certificate cannot be installed. I presume this is because my private key does not match the public key of the certificate.

How can I get a wildcard certificate working with my ABAP system? Do I need to somehow change the private key of my system?

Thanks in advance
