Question

尝试通过Linux机器上运行的Java应用程序通过Windows身份验证连接到MS SQL服务器。连接字符串：

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

连接错误：

如何理解该错误以及如何解决？

UPD

如果我按照以下说明删除authenticationScheme=JavaKerberos：

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

我有错误：

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]

UPD 2

按照以下说明离开authenticationScheme=JavaKerberos并删除integratedSecurity=true：

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

给出错误：

Answer 1

该应用程序运行在Linux计算机上，该计算机是否已加入Windows域？

如果没有，那么您可能需要使用SQL身份验证：

jdbc:sqlserver://192.168.1.50\SQLEXPRESS;user=MyUserName;password=*****;

否则，可以尝试不使用authenticationScheme=JavaKerberos和指定默认端口的情况：

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

从JDBC连接到MSSQL服务器时出现Windows身份验证问题
