Re: with Impala ODBC Server returned error for request OpenSession user is not authorized to delegat

This looks like IMPALA-6973, Impala is checking 'auth_to_local' for the user authentication but not for the delegated user. As per the JIRA the workaround is to use uppercase when specifying the <user allowed to delegate> for Impala.

 

What do you think?

it is not the problem since in both configurations (AD and Impal) the user xxx is in lowercase. another clue?
