How to Use Windows Authentication to Access SQL Server Through a ASP. NET Web Application. This sample application demonstrates how to use Windows authentication for Web- based intranet applications to access a SQL Server database using ASP.

NET. Most of the intranet Web applications prefer to use Windows authentication because they are going to used by internal users. We need to configure the following four different areas to access Windows integrated security: SQL Server. IIS Web Server. ASP. Net web application.

How to get Active Directory Users and Computers with Exchange Management Tools working in Windows 7. The problem: using ASP.NET Forms authentication and IIS Windows authentication in the same application. Unfortunately, one of the limitations of a single-stage.

Connection. String. SQL Server be running on same IIS machine. If both are on different machines, we should go for analternative security model such as Forms authentication, which is not covered in this article. The access users must be in the same domain where the Web server is running.

Configuring SQL Server. To configure SQL Server for Windows integrated security: From the Windows Start menu, choose Microsoft SQL Server, and then choose Enterprise Manager. Open the node for the server and expand the node for the database you want to give users permissions for.

Right- click the Users node and choose New Database User. In the Database User Properties dialog box, enter domain\username in the Login name box, and then click OK. Alternatively, configure the SQL Server to allow all domain users to access the database. Configuring IISYou need to configure your application in IIS to turn off anonymous access and turn on Windows authentication.

To configure IIS for Windows integrated security: In Windows, open the Internet Information Services administration tool. Open the node for your server, and then open nodes until you find the node for your application, typically under Default Web Site. Right- click your application and choose Properties.

In the Directory Security tab, click Edit. In the Authentication Methods dialog box, clear the Anonymous Access box and make sure Integrated Windows authentication is checked. Click OK to close all the dialog boxes.

Configuring the ASP. NET Web Application. In the application configuration file (Web.

IIS 7. 0 Two- Level Authentication with Forms Authentication and Windows Authentication. One of the key improvements granted by the ASP.

NET integration in IIS 7. With this, it becomes very easy to write custom authentication methods using . NET (that previously required ISAPI filters and C++ code), and use these solutions in a way that integrates seamlessly into the IIS security model.

Update: We recently launched a service that significantly helps you understand, troubleshoot, and improve IIS and ASP. NET web applications. If you regularly troubleshoot IIS errors, manage Windows Servers, or tune ASP. NET performance, definitely check out the demo at www. Popular example – everyone’s favorite Forms authentication, backed by a Membership credential store and login controls, being used to secure access to your entire Web site including your images, PHP pages, CGI applications, and so on.

The problem: using ASP. NET Forms authentication and IIS Windows authentication in the same application.

Unfortunately, one of the limitations of a single- stage authentication model is that it is done in a single stage (imagine that!). For some reason, you want all users to first log in using their Windows credentials, and then log in using their Membership credentials and Forms authentication. But, in Integrated mode, both Windows and Forms authentication run during the single stage authentication process, which makes it impossible to first authenticate with Windows authentication, and second authenticate with Forms authentication. Additionally, because Forms authentication is enabled for the entire application, there is no way to enable it for a part of your app and not for another – which presents a problem, because Forms authentication’s 3. WWW- Authenticate” challenge used by Windows authentication. The answer lies in separating the windows authentication and forms authentication transactions into two separate pages – one page will be the gateway page that requires Windows authentication, and the other page (or pages) will require forms authentication. Luckily, this maps well into the Forms Authentication model of having a separate login page which will become our gateway.

Secondly, using a wrapper module, we will disable Forms authentication for the gateway (login) page. This way, our Windows authentication challenge will work correctly. This works as follows (as shown in the diagram above): 1)      Anonymous request to page. You’ll need to: 1.

Unlock the < anonymous. Authentication> and < windows. Authentication> configuration sections before you can use them in web.

Authentication> %windir%system. Authentication. 2. Register the forms authentication wrapper configuration section in your web. Forms. Auths. Module configuration section –> < config. Sections>  < sectionname=“forms. Authentication. Wrapper“            type=“Mvolo. Modules. Forms. Auth.

Configuration. Section“ /> < /config. Sections> 3. Replace the built- in Forms Authentication module with the wrapper: < system.

Server>  < !– Replace the built- in Forms. Authentication. Module with the Forms. Auth. Module wrapper –>  < modules>    < removename=“Forms.

Authentication“ />    < addname=“Forms. Authentication“type=“Mvolo. Modules. Forms. Auth. Module“ />  < /modules> < /system. Server> 4. Set the required settings for the gateway page: < !– Disable Forms Authentication for this URL –> < locationpath=“login.

Disable Forms Authentication –>   < forms. Authentication. Wrapperenabled=“false“ />  < system. Server>    < security>      < !– Enable IIS Windows authentication for the login page –>      < authentication>        < windows. Authenticationenabled=“true“ />        < anonymous. Authenticationenabled=“false“ />      < /authentication>    < /security>  < /system. Server> < /location> That should do it. Some caveats: – The wrapper uses reflection to invoke the real forms authentication module.

This means that it must either run in applications in Full trust, or be in the GAC.– This is for Integrated mode applications on IIS 7. Previous versions of IIS or Classic mode applications dont require this as they use two- phase authentication. Downloads: 1)     Sample application and Forms. Auth. Module wrapper v.
