Namespace:   System.Web
Assembly:  System.Web (in System.Web.dll)

public WindowsIdentity LogonUserIdentity {
	[AspNetHostingPermissionAttribute(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Medium)]

Property Value

Type: System.Security.Principal.WindowsIdentity

A WindowsIdentity object for the current Microsoft Internet Information Services (IIS) authentication settings.

Exception Condition

The Web application is running in IIS 7 integrated mode and the PostAuthenticateRequest event has not yet been raised.

The LogonUserIdentity property exposes the properties and methods of the WindowsIdentity object for the currently connected user to Microsoft Internet Information Services (IIS). The instance of the WindowsIdentity class that is exposed by LogonUserIdentity tracks the IIS request token and provides easy access to this token for the current HTTP request being processed inside of ASP.NET. An instance of the WindowsIdentity class is automatically created so it does not need to be constructed to in order to gain access to its methods and properties.

The following code example shows how to retrieve the LogonUserIdentity property for the current user and write out the values of each item in a text file. Place this code on the ASP.NET page referenced by the form's ACTION attribute.
