[stunnel-users] Stunnel-Openssl: Problems with certificate chain

[Pietro Di Primo]

Hi,
My name is Pietro Di Primo and I work on the INFN Grid project
(http://grid.infn.it/).
I'm trying to develop an application based on stunnel.
Everything works well when I use user certificates (signed by our CA), but
i need to use (on the client side) a particular proxy.
This proxy contains a public and a private key, and the public key of the
user that generated it (I atteched a file with a such proxy).
On the server side I have the CA certificate but not the user's one, so I
can't verify the client (unable to get local issuer certificate).
I tried to get the user certificate using the SSL_get_peer_cert_chain
function on the server, but it returns NULL.
On the client side I tried SSL_CTX_use_certificate_chain_file,
Also I tried to get a STACK_OF(X509) and use SSL_CTX_use_certificate (for
proxy certificate), and SSL_CTX_add_extra_chain_cert (to include the
user's certificate), but it still doesn't work.

Can you help me please?

Best Regards
