title: Set Kettle DB Connection password from Environment Variable
body: <p>How do I set a database connection's password to use an environment variable. I cannot add these to the kettle.properties file (security policy). When I click control-space on OSX, nothing happens. If I try and paste the string <code>${PASSWORD}</code> directly into the password field, it does not allow it, due to the presumably non-alphanumeric <code>'$'</code> char.</p>
  
  <p>The other fields as shown below work fine. </p>
  
  <p>The <strong>EDIT Connection</strong> dialog below shows the field in red, which is what I want to achieve logically.</p>
  
  <p>Using PDI Community 8.2, on Mac OSX Mojave.</p>
