dsn-less odbc connections possible?

I use a dastabase.yml file like this:

development:
  adapter: sqlserver
  mode: ODBC
  dsn: Driver={SQL Server};Server=MyMachine;Database=my_database

As far as I know, it should work with most dsn strings.

What dsn parameter is used in the call ODBC::connect(dsn, username, password)?
