我的使用场景是用EF连接AWS的mysql RDS，会偶发性的出现A call to SSPI failed错误，

System.AggregateException: One or more errors occurred. ---> System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> System.ComponentModel.Win32Exception: The message or signature supplied for verification has been altered

最后在StackOverflow里有人说在连接字符串里面加入SslMode=None，可以解决这个问题。
