We are using Windows 2008 R2 Standard client with DotnetCore 2.0 for the client
The destination is Amazon Aurora

The exception call stack looks very similar to https://stackoverflow.com/questions/46518563/net-mysql-error-a-call-to-sspi-failed-message...

The common factor is that the back-end is Amazon Aurora.

Here is my stack trace
  
  > Error Message: Authentication failed, see inner exception.
