title: NodeJS unable to read default CAs in ubuntu
body: <p>On our testing environment we are connecting to another server with SSL signed by our company. Every time connection is made nodejs throws
  <strong>UNABLE_TO_VERIFY_LEAF_SIGNATURE</strong>.
  I have found workarounds by setting <strong>rejectUnauthorized: false</strong>, but this is not aplicable in our case.</p>
  
  <p>The certificates are added to <strong>/etc/ssl/certs</strong> and tested with the environment variable <strong>SSL_CERT_DIR</strong> to be either <strong>/etc/ssl</strong> anb <strong>/etc/ssl/certs</strong>, but no result.</p>
  
  <p>Also, it is not preferable to add somewhere in our files the certificate and add it to every request.</p>
