If you are using the document "Vertica Integration with Tableau 10: Tips and Techniques" (located here http://my.vertica.com/docs/Ecosystem/Vertica_Tableau_Tips_and_Techniques.pdf). In the document dated 9/12/2016 there are typos when referencing the parameter 'odbc-connect-string-extras' - it is represented at least twice as "odbc-connect-string-extra" or missing the "s" at the end of "extraS".
If the .TDC files do not match, it will generate what looks like a "bad password" error or will prompt for login to the Vertica database.
