For a customer we need to order a SSL certificate, normally this would be done by their help-desk and we provide the CSR. But as the old certificate will expire soon, and their help-desk need about 7 days to order the new one, I would like to order one for them myself so the site wont go down.
Now, is it possible to have the same CSR signed twice? Once by my CA of choice and once by their CA of choice? Or do I need to regenerate a CSR for the help-desk?
