了解连接字符串atrributes

我是C#和.net的新手。我正在尝试使用测试控制台应用程序测试我的Nhibernate配置。

这是我的测试控制台应用

class Program
{
    static void Main(string[] args)
    {
        try
        {
            NHibernateBase NHB = new NHibernateBase();
            NHB.Initialize("NHibernate.GuitarStore");
            System.Console.WriteLine("NHibernate.GuitarStore assembly initialized.");
            System.Console.ReadLine();
        }
        catch (Exception ex)
        {
            string Message = ex.Message;
            if (ex.InnerException != null)
            {
                Message += " - InnerExcepetion: " + ex.InnerException.Message;
             }
        System.Console.WriteLine();
        System.Console.WriteLine("***** ERROR *****");
        System.Console.WriteLine(Message);
        System.Console.WriteLine();
        System.Console.ReadLine();
        }
        }
    }

当我运行上述程序时，我得到错误：

***** ERROR *****
Login failed for user 'BUGZILLA'Silon'.

这是我的app.config 中的连接字符串

connectionString="Data Source=localhost;Initial Catalog=myGuitarStore;Integrated Security=True

我认为这与连接字符串的集成安全部分有关。

问题是我不理解连接字符串中的属性（及其含义），而且我似乎找不到任何一篇足够容易地表达它们的文章。

----如果你需要它来理解问题，这里有NHibernateBase类

 public class NHibernateBase
{
    private static Configuration Configuration { get; set; }
    protected static ISessionFactory SessionFactory { get; set; }
    private static ISession session = null;
    private static IStatelessSession statelessSession = null;
    public static Configuration ConfigureNHibernate(string assembly)
    {
        Configuration = new Configuration();
        Configuration.AddAssembly(assembly);
        return Configuration;
    }
    public void Initialize(string assembly)
    {
        Configuration = ConfigureNHibernate(assembly);
        SessionFactory = Configuration.BuildSessionFactory();
    }
    public static ISession Session
    {
        get
        {
            if (session == null)
            {
                session = SessionFactory.OpenSession();
            }
            return session;
        }
    }
    public static IStatelessSession StatelessSession
    {
        get
        {
            if (statelessSession == null)
            {
                statelessSession = SessionFactory.OpenStatelessSession();
            }
            return statelessSession;
        }
    }
    public IList<T> ExecuteICriteria<T>()
    {
        using (ITransaction transaction = Session.BeginTransaction())
        {
            try
            {
                IList<T> result = Session.CreateCriteria(typeof(T)).List<T>();
                transaction.Commit();
                return result;
            }
            catch (Exception ex)
            {
                transaction.Rollback();
                throw ex;
            }
        }
    }
