在服务器中，我有以下代码：
certificateFile = /opt/openssl-1.0.0a/ssl/certwork/server.crt
privatKeyFile = /opt/openssl-1.0.0a/ssl/certwork/server.key
ctx = Ctx::client_server(certificateFile, privateKeyFile);
ctx->context()->verify_mode = SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT | SSL_VERIFY_CLIENT_ONCE;
ctx->context()->client_CA = SSL_load_client_CA_file("/opt/openssl-1.0.0a/ssl/certwork_client/ca.crt");
的context()调用方法OpenSSL的ssl.h.
我创建的服务器CA（认证授权）和服务器证书用下面的命令：我创建的客户端CA和客户端证书与以下命令
cd /opt/openssl-1.0.0a/ssl
mkdir certwork
chmod 600 certwork
cd certwork
openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt
openssl genrsa -des3 -out server.key 4096
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt
：
cd /opt/openssl-1.0.0a/ssl
mkdir certwork_client
chmod 600 certwork_client
cd certwork_client
openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt
openssl genrsa -des3 -out client.key 4096
openssl req -new -key client.key -out client.csr
openssl x509 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt
我可以获得服务器端身份验证通过证书工作，但是当我使用证书添加客户端身份验证时，出现tlsv1 alert unknown ca:s3_pkt.c:1193:SSL alert number 48错误。
我设置客户端使用服务器的CA（/opt/openssl-1.0.0a/ssl/certwork/ca.crt），我设置服务器使用客户端的CA文件（/opt/openssl-1.0.0a/ssl/certwork_client/ca.crt）。
我错过了什么？
