问题：
SSL连接失败，没有来自服务器的证书请求，从运行在Java 6上的本地Websphere连接到AWS上的Nginx
龙俊美
我很难连接到具有客户端身份验证的服务。该服务(“SecureService”)在AWS上。客户端在我的Mac上的Linux虚拟机上。SecureService上的Nginx对我在端口443上访问的资源实施客户端身份验证。我可以使用概念验证Java独立应用程序(openjdk 1.8.0_60)或其他客户端(wget、openssl)从同一个VM连接到同一个SecureService获得成功的响应，但不能从Websphere上托管的同一个Java代码获得响应(当然依赖于较旧的库和IBM J9 VM，build 2.6，JRE 1.6.0)。但是，当将SecureService主机名重新映射到/etc/hosts中的127.0.0.1时，Websphere上与相同的java代码成功连接到本地openSSL服务器，该服务器需要来自相同证书颁发机构的客户端身份验证。失败连接中来自SecureServer的响应报告“400没有发送所需的SSL证书”...“400错误请求”，但是tcpdump数据包捕获显示它没有发送证书请求，而在所有其他情况下都是如此。这令人困惑，并使我认为ClientHello消息中有服务器不喜欢的东西，尽管成功和失败连接中的ClientHello消息非常相似。
另一个非常奇怪的细节是，tcpdump从未在通信失败时捕获从我的客户端到服务器的第一个TCP SYN数据包，而它捕获其余数据包（从服务器的SYN ACK，然后从客户端的ACK）以及所有其他通信中的所有数据包（SYN、SYN ACK、ACK）。
所有通信的所有部分都使用TLSv1.2。
连接失败：

已解决-我发现Nginx服务器需要在客户机Hello中指定“server_name”扩展。事实上，以下openssl命令会提示服务器发出证书请求。。。
/usr/local/Cellar/openssl/1.0.2e/bin/openssl s_client -cert client_identity.crt -key client_identity.key -connect SecureServerHostName:443 -debug <post_request.txt -tls1_2 -servername SecureServerHostName
...而省略“-servername”选项则不会。
我将如何强迫WebsphereAS添加该扩展是另一双鞋。通过更新TLS协议的实现，升级Java版本可能会有所帮助。
更新:是的，将IBM JDK从1.6升级到1.7.1成功了，生成了带有服务器名称指示的客户机问候消息，正如这里提到的(默认情况下，Java SE 7启用了服务器名称指示(SNI))。).

我们的应用程序可以使用Active Directory用户和组。我们在端口389上使用LDAP进行Active Directory操作。现在，我们的一个客户机希望我们添加一个使用LDAP+SSL进行Active Directory通信的选项。 他们告诉我们，他们在域上安装了一个本地CA，并对LDAP使用自签名证书。他们还告诉我们，他们会提供证书，不需要相互信任，我们应该使用Windows证书存储。
