   An example DSN for a MySQL setup: 
  
positive.code: YubiKey counter data from one of the existing servers. To do so, the server 
  you want to sync from needs to be configured to allow it. Do this by editing 
  /etc/yubico/val/ykval-config.php on the existing server, adding the new 
  servers IP address to the '__YKRESYNC_IPS__' setting. You'll most likely want 
  to add the IP to the '__YKVAL_ALLOWED_SYNC_POOL__' setting as well. You also 
  need to edit this file on the new server, adding the existing server(s) IP
  address(es) to '__YKVAL_ALLOWED_SYNC_POOL__'.
  
  Once these permissions have been configured, you can initiate the full sync 
  by running the following command from the new server:
  
negative.code: user@val:~$

  To improve database performance you can use persistent database connection so that each request doesn't require a new connection to be setup. To enable this modify `__YKVAL_DB_OPTIONS__` as follows:
  
  [source, php]
  $baseParams['__YKVAL_DB_OPTIONS__'] = array(PDO::ATTR_PERSISTENT => true);
