Question

I am attempting to make a connection to a Dynamics GP SQL Server Database using the currently logged in credentials from GP. (for context http://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.

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

Thanks

This Class will retrieve the proper data that you need for the connection.

public class GPUser
{
    public readonly static string DataBase = Dynamics.Globals.IntercompanyId.Value;
    public readonly static string UserID = Dynamics.Globals.UserId.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 SqlConnectionStringBuilder ConnectionString
    {
        get 
        {
            return new SqlConnectionStringBuilder
            {
                DataSource = DataSource,
                UserID = UserID,
                Password = Password,
                ApplicationName = ApplicationName,
                InitialCatalog = DataBase
            };
        }

    }
    public readonly static short CompanyId = Dynamics.Globals.CompanyId.Value;
    public readonly static DateTime UserDate = Dynamics.Globals.UserDate.Value;
}

Passing GPUser.ConnectionString into this code will create a valid SQLConnection object that you can use to connect to the GP Database.

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.");
    }
}
