why? what are you expecting to gain from this configuration? If client
and server can share secret key material, you might decide to use a
different handshake mode entirely, like PSK.

It's generally good practice to ensure that secret key material is
limited to the machines that truly need it.

In TLS, the client will never send a certificate unless the server asks

what APIs have you invoked? when does your program invoke them? being
specific will help.
In particular, have you invoked gnutls_certificate_server_set_request()
on the server side before the handshake is underway?
