正在尝试通过运行在linux计算机上的java应用程序的windows身份验证连接到ms sql server。连接字符串：
jdbc:sqlserver用法：/192.168.1.50\sqlexpress:1433;databasename=mydata；integratedsecurity=true；authenticationscheme=javakerberos
出现连接错误：

如何理解这个错误以及如何修复它？
升级版
如果我移除 authenticationScheme=JavaKerberos 具体如下：

jdbc:sqlserver://192.168.1.50\SQLEXPRESS:1433;DatabaseName=MyData;integratedSecurity=true;

我有个错误：

java.sql.SQLException: No suitable driver found for
       at java.sql.DriverManager.getConnection(DriverManager.java:689) ~[?:1.8.0_171]
       at java.sql.DriverManager.getConnection(DriverManager.java:247) ~[?:1.8.0_171]

升级版2
离开 authenticationScheme=JavaKerberos 以及移除 integratedSecurity=true 具体如下：

jdbc:sqlserver://192.168.1.50\SQLEXPRESS:1433;DatabaseName=MyData;authenticationScheme=JavaKerberos

给出错误：
