C# app.config

In a C# 2010 windows application, I am using the following to connect to a sql server 2008 r2 database.

The app.configuration file looks like the following:

          providerName="System.Data.SqlClient" />
 
The problem is once someone besides myself runs the application, it will not run correctly.
Thus I am assuming that the Integrated Security=True needs to be changed to a username and password that is setup for the application to run.

Is my assumption correct? If not, would you be able to tell what I need to do so someone besides myself can run the application?
