我们有一个Java应用程序在ECS中的AWS Linux docker实例上运行。此应用程序需要使用集成身份验证连接到本地Sql Server实例。在普通的AWS Linux EC2实例上，它可以正常工作，但在EC2上，应用程序失败，并显示“集成身份验证失败”。消息。
由于我们在EC2上确认了该应用程序，sql server驱动程序和连接字符串的有效性，因此我们认为这是有效的。是否有任何原因会使ECS失败？我们一直在检查IAM权限（还没有运气），但是ECS可能与Kerberos有关吗？我们将驱动程序配置为使用JavaKerberos。
连接字符串
jdbc:sqlserver://SQLSERVER1\SQLINSTANCE1;databaseName=MyDB;integratedSecurity=true;authenticationScheme=JavaKerberos;userName=myuser@MY.DOMAIN.COM;password=mypassword
