am attempting to make a connection to a Dynamics GP SQL Server Database using the currently logged in credentials from GP. (for contexthttp://blogs.msdn.com/b/developingfordynamicsgp/archive/2008/10/02/why-does-microsoft-dynamics-gp-encrypt-passwords.aspx)

Using the code provided from the documentation of GPConnNet.dll I should be able to get a connection but have been unable to do so for non-sa users, sa and dynsa work fine. I am receiving a login failed sql server error. I've tried both overloads of the Connect method, using the SqlConnection and an OdbcConnection.

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString);
SqlConnection sqlConn = new SqlConnection();
if (sqlConn.State != ConnectionState.Open)
{
    GPConnection.Startup();
    var gpconn = new GPConnection();
    gpconn.Init(<Key1>, <Key2>);
try
{
    sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog);
    gpconn.LoginCompatibilityMode = false;
    gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password);
    if (gpconn.ReturnCode != 1)
         throw new AuthenticationException("Could not authenticate with the GP credentials.");
}
catch (System.Runtime.InteropServices.SEHException)
{
    throw new AuthenticationException("Could not authenticate with the GP credentials.");
}
}

The information in the connection string is coming from the Microsoft Dexterity toolkit.

public class GPUser
{
    public readonly static string DataBase = Dynamics.Globals.IntercompanyId.Value;
    public readonly static string UserID = Dynamics.Globals.UserName.Value;
    public readonly static string Password = Dynamics.Globals.SqlPassword.Value;
    public readonly static string DataSource = Dynamics.Globals.SqlDataSourceName.Value;
    public readonly static string ApplicationName = string.Format("{0}{1}", App.ProductName, "(gp)");
    public static string Server
    {
        get
        {
            //Returns the Server from the ODBC DSN
        }
    }
    public static SqlConnectionStringBuilder ConnectionString
    {
        get 
        {
            return new SqlConnectionStringBuilder
            {
                DataSource = Server,
                UserID = UserID,
                Password = Password,
                ApplicationName = ApplicationName,
                InitialCatalog = DataBase
            };
        }

    }
}

Is there something security related that is required on the user? Is there something in the GPConnection code that I'm missing?

Thanks
