Is it possible to specify Active Directory username and password in connection string? My organization uses Active Directory to control access to our databases. Building web applications and as part of our CI process I would like to specify the credentials in the connection string. 

Is it possible to pass AD credentials in a connection string or do I need a standard SQL account for these items?
You can have your app impersonate a windows user and do the connection that way. Example for ASP.net app.
