Good morning everyone,

I’m running into an issue using a SharePoint workflow project (C#, VS 2008) and connecting to a database. Here is my database connection string:

Data Source=DBSERVER;Initial Catalog=DBNAME;Integrated Security=True;

When I attempt to run the following code I get the following error … 

SqlConnection dbEngine = new SqlConnection(Constants.DBCONNECTION_STRING); dbEngine.Open();

‘Login failed for user ‘DOMAIN\MACHINE_NAME$”

What I need it to do is pass through the logged in user’s credentials. I’ve got impersonation turned on but it doesn’t seem to be passing through. Any suggestions would be very much appreciated.

Thank you in advance for any advice,

Scott Vercuski

  1. Any DB access should run as a Windows Service account for security and connection pooling reasons.
