Possible.
A server sends a list of accepted issuer certificates.
If your cert was issued by one of these certificates,
it's OK...
But normally client certificates and server certificates
are signed with different keys and have different issuer certificates...

very confusing.
That is the reason in a later version of cURL
cou can set the certificate / private key / passphrase for private key
with seperate parameters (and you can use a private key in in
a crypto device...)
