This sample works only with SQL Server 2008. It will not work with any version of SQL Server earlier than SQL Server 2008.
This sample shows how to get mutual Kerberos authentication by using OLE DB in SQL Server Native Client.
SQL Server samples and sample databases must be downloaded and installed before you can view or work with them. For more information, see Considerations for Installing SQL Server Samples and Sample Databases.
Scenario
For more information about SPNs and Kerberos authentication, see Service Principal Name (SPN) Support in Client Connections in SQL Server Books Online.
Languages
This sample uses Visual C++.
Prerequisites
Before running this sample, make sure the following software is installed:
-
SQL Server or SQL Server Express, including Database Engine.
You can download SQL Server Express from theMicrosoft Download Center .
-
The SQL Server Database Engine samples. These samples are included with SQL Server. You can download the latest version of the samples at the
Microsoft SQL Server Developer Center .
-
.NET Framework SDK 2.0 (or later) or Microsoft Visual Studio 2005 (or later). You can obtain .NET Framework SDK free of charge. For more information, see Installing the .NET Framework Documentation.
Building the Sample
-
You must specify a server. In OLEDB_SPN.cpp, change "MyServer" to a machine name that has an instance of SQL Server 2008 (or later).
-
You will also have to specify a customer-provided SPN. In OLEDB_SPN.cpp, change " CP_SPN " to a customer-provided SPN.
-
Make sure your INCLUDE environment variable includes the directory that contains sqlncli.h.
-
If you are using Visual Studio, load the OLEDB_SPN.sln file and build it.
-
If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt. Pass in the OLEDB_SPN.sln file, as follows:
MSBuild OLEDB_SPN.sln
Running the Sample
-
From Visual Studio, invoke Start Without Debugging (CTRL+F5).
-
If you built with MSBuild.exe, invoke OLEDB_SPN.exe.
