I've been given a requirement of providing a client certificate to authenticate between two application's web services. The other application (that I don't host) is requiring an SSL client certificate that is signed by a 3rd party CA (ie. Symantic, RapidSSL, etc.) and not be self-signed. After going through most of the CA's websites and Googling around, I can't seem to find a proper answer on how to get a signed client cert.
Is there something I'm missing in CSR documentation that'll allow me to generate a client certificate? I've seen a few of the bigger CA's offering "managed PKI" services which are about the only mention of signed client certificates that I can find, however, those seem like they might be terribly expensive services for what I'm trying to get.
Thanks in advance for the help.
