我在使用TLS1.2连接到SQL Server 2012时遇到问题。以下是NMap的代码，网络跟踪和输出。从trace和Nmap输出我认为看起来有一个密码问题，但我不确定。跟踪告诉我握手从TLS 1.2开始，然后连接关闭，不知道为什么。如果是密码问题，握手如何确定使用哪个密码以及可能的密码存储在哪里？
使用：IBM Java 6，SQL Server 2012，sqljdbc4.jar
由于
public static void doConnect2()

try
{
System.setProperty("javax.net.debug", "all");
System.setProperty("javax.net.debug","ssl:handshake:verbose");
System.setProperty("com.ibm.jsse2.overrideDefaultTLS","true");
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
Connection conn = DriverManager.getConnection(
"jdbc:sqlserver://MIMV-DBTE02;databaseName=CMS",
"userid",
"password");
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
