Conneting to MySQL db

I have a CF site I am transfering to a new hosting company. I'm having trouble connecting to the db. I did not develope this site. It seems the developer used a configuration.txt file to connect to the database. See below. The part that stands out is that there is no username and password. What is the attribute name for the username and password. I tried username: and password: but they do not work.
