在我的apache web-server中，有一条路径，客户端必须使用有效的证书进行身份验证。
有时会有一个无法连接的客户端（soap-webservice），我的apache返回403“sslv3警告错误证书（SSL警报号42） - 证书中的主体CN不是服务器名称或与CA相同！？”我需要检查它使用的原因和证书。
我为mod_ssl和一个自定义日志设置了trace3 loglevel，如下所示：
CustomLog /var/log/httpd-ssl.log "%t %h \"%{User-agent}i\" %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %>s \"%{SSL_CLIENT_S_DN_CN}x\" <<<%{SSL_CLIENT_CERT}x>>>"
<IfModule mod_ssl.c>
ErrorLog /var/log/apache2/ssl_engine.log
LogLevel trace3
</IfModule>
在第一个文件日志中，我可以看到可以连接的客户端的所有信息，但是当客户端失败时，没有有用的信息：
[16/Feb/2019:11:01:43 +0100] XXX.XXX.XXX.XXX "IBM WebServices/1.0" - - "POST MYSECRETPATH HTTP/1.1" 403 "-" <<<->>>
在第二个我可以看到一些信息，如：

但是没有什么真正有用的东西。
我想记录/写入apache正在阅读但不接受的证书。我该如何记录？
您可以通过添加以下JVM命令行参数在Application Server JVM配置中启用SSL调试日志，然后重新启动Application Server：
-Djavax.net.debug =所有
根据您的WAS版本，添加上述参数通常通过导航到WAS管理控制台>服务器>应用程序服务器> YourServer>进程管理> Java虚拟机>通用JVM参数来完成
