WindowsAuthenticationModule Class
Sets the identity of the user for an ASP.NET application when Windows authentication is enabled. This class cannot be inherited.
Assembly: System.Web (in System.Web.dll)
The WindowsAuthenticationModule type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | WindowsAuthenticationModule | Creates an instance of the WindowsAuthenticationModule class. |
| Name | Description | |
|---|---|---|
![]() | Dispose | Releases all resources, other than memory, used by the WindowsAuthenticationModule. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | Init | Initializes the WindowsAuthenticationModule object. |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
When the authentication Mode is set to Windows, the WindowsAuthenticationModule sets the User property of the current HttpContext to an IPrincipal object that represents the Windows identity supplied by IIS for the current request. If IIS uses anonymous authentication, then the WindowsAuthenticationModule uses the identity returned by the GetAnonymous method.
The WindowsAuthenticationModule exposes an Authenticate event that enables you to provide a custom IPrincipal object for the User property of the current HttpContext. The Authenticate event is accessed by specifying a subroutine named WindowsAuthentication_OnAuthenticate in the Global.asax file for your ASP.NET application.

In IIS 7.0, using the WindowsAuthenticationModule class with the FormsAuthenticationModule class is not supported. For more information about compatibility issues in Integrated mode, see Moving an ASP.NET Application from IIS 6.0 to IIS 7.0. |
The following code example uses the WindowsAuthentication_OnAuthenticate event to set the User property of the current HttpContext to a custom IPrincipal object.
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
