Sql server 从Linux通过Windows身份验证连接到AWS上的MSSQL DB

我已经创建了一个新的广告用户，并将其与数据库集成以进行身份验证。数据库托管在AWS上&我可以使用MSSQL进行连接，但我想通过我的代码来实现这一点。我已经做了一些研发工作，并且到处提到使用javakerberos进行身份验证。我创建了连接字符串，如-

spring.datasource.url=jdbc:sqlserver://mssql.host.com:1433;databaseName=db_name;integratedSecurity=true;authenticationScheme=JavaKerberos
spring.datasource.username=my_user

这是我在承载应用程序的linux机器上收到的错误-

ERROR o.a.tomcat.jdbc.pool.ConnectionPool
                                 - Unable to create initial connections of pool.
com.microsoft.sqlserver.jdbc.SQLServerException: Cannot login with Kerberos principal my_user, check your credentials. Kerberos Login failed: Integrated authentication failed. ClientConnectionId:2ee0b176-ebf7-46fe-91af-b16dead75108 due to javax.security.auth.login.LoginException (connect timed out)

我接下来需要执行哪些步骤才能使其成功
