无法使用NHibernate登录到SQL Server，但使用Management Studio或sqlcmd可以正常工作

Question

Im getting login failed error when trying to connect to my database using NHibernate:

var config = Fluently.Configure()
              .Database(MsSqlConfiguration
              .MsSql2005
              .ConnectionString("Data Source=SERVER1\\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=xxx"))
              .Mappings(x => x.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly()));

With Error 18456 State 5 in the log viewer in SQL Management Studio.

But using sqlcmd or Management Studio it works fine (using Windows Auth)!

What could be the problem?

EDIT The NHibernate exception:

Test method ProjektLogg.Tests.NHibernateTests.ShouldBeAbleToGenerateFactory threw exception: 
FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

 ---> NHibernate.HibernateException: Login failed for user XXX-INTRANET\username. ---> System.Data.SqlClient.SqlException: Login failed for user XXX-INTRANET\username.

Answer 1

That error message means "Invalid UserID". If you're running IIS, make sure your application pool uses the same identity as the user who you are connecting to the database with in management studio.

If you're not running under IIS, make sure your current user account (Windows) can access the database, as you're using Integrated Security.

EDIT: Hang on, you're missing Initial Catalog . Try this:

"Data Source=SERVER1\\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=YourDatabase"

Answer 2

I cleaned the whole solution now it works. Sorry to waste your time, guys. Appreciate your answers.

Answer 3

I faced a similar problem and I realized that unlike Entity Framework, (Fluent)NHibernate does not create a database for you. The solution was to create an empty database.

The following segment in your ConnectionString means that database xxx must already exist:

Initial Catalog=xxx

Answer 4

我无法使用集成安全性，我必须在连接字符串中提供用户和密码。
