dotnetcore：无法访问 Kerberos 票证。确保 Kerberos 已使用“kinit”初始化

Question

我尝试使用 vscode 在 ubuntu 上运行和 aspnet 核心应用程序。当运行应用程序时，它给了我这个错误：

  System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnectionPool pool, DbConnection owningObject, DbConnectionOptions options, DbConnectionPoolKey poolKey, DbConnectionOptions userOptions)
   at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnection owningObject, DbConnectionOptions userOptions, DbConnectionInternal oldConnection)

但我没有使用集成身份验证，我的连接字符串如下所示："DefaultConnection": "Data Source=localhost;Initial Catalog=School360Db;User Id=[user];Password=[password];Trusted_Connection=True;MultipleActiveResultSets=true"

我在 Windows 上测试了它，它可以工作！

有什么想法吗？

Answer 1

如 @jcmordan 在 cmets 中所述 - 设置 Trusted_Connection=False。

Answer 2

我也遇到过类似的问题。

我正在使用 linux 操作系统和 Rider IDE，

我通过更改 appsettings.json 中的连接字符串解决了这个问题：

"ConnectionStrings": {
"DefaultConnection": "Server=localhost;Database=ExampleDB;User=SA;Password=mypassword;ConnectRetryCount=0;MultipleActiveResultSets=true"

}

试试这个格式。
