Project Description:
We need help to setup a working database connection from a Ruby on Rails app running on www.heroku.com to a Microsoft SQL Server 2012 database running on a Windows Server 2008 R2 Enterprise 64-bit.

We have tried to setup the connection ourselves but get the error listed below.

The Rails source code is hosted on GitHub and you will get access to the repo so that you can commit necessary changes to the code.

> rails -v
Rails 3.2.8

> ruby --version
ruby 1.9.3p194

Heroku URL
