Wordpress: External Database Authentication and Tbdev passhash

Good day! Required to connect the database from TBDev to WordPress with the plugin "External Database Authentication Reloaded". Plug-in settings in the fields have a 2 fields: Username and Password. Then choose "Other" method: External Database Source Fields but TBDEV uses this algorithm:

$passhash = md5($secret. $password. $secret); 

Where: $passhash and $secret - existing fields in a database table (where TBDev based) these fields in TBDev database $secret can not add to the settings in addition to username and password so it seems, by means of a plug joint authorization to do will be impossible. But if you have an idea how to do it - I will be very happy and eternally grateful!
