+<p>Note that the client will not send a certificate unless the value for the <code>verify</code> option is set to <code>verify_peer</code>. This means that <code>fail_if_no_peer_cert</code> only applies when combined with the <code>verify</code> option. The <code>verify_fun</code> option allows greater control over the client certificate validation.</p>
