ResolutionUse a TDC file must in order to accomplish mutual SSL authentication. See an example below:
<?xml version='1.0' encoding='utf-8' ?>
<connection-customization class='presto' version='10.5' enabled='true'>
<vendor name='presto' />
<driver name='presto' />
<customization name='odbc-connect-string-extras' value='TRUSTEDCERTS=X:\XXXX.pem'/>
If the data source does not require SSL from the client machine, then the Enable SSL checkbox should work without a TDC file. However, please not that in most cases, this is not how the data source is set up and requires the client cert.
Important: Tableau does not test or support TDC files. These files should be used as a tool to explore or occasionally address issues with your data connection. Creating and maintaining TDC files requires careful manual editing, and there is no support for sharing these files.
