<para>The <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> ensures that the <see cref="P:System.Web.HttpContext.User" /> property of the current <see cref="T:System.Web.HttpContext" /> instance is set to an <see cref="T:System.Security.Principal.IPrincipal" /> object for each request. The <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> examines the <see cref="P:System.Web.HttpContext.User" /> property after the <see cref="E:System.Web.HttpApplication.AuthenticateRequest" /> event and before the <see cref="E:System.Web.HttpApplication.AuthorizeRequest" /> event. If the <see cref="P:System.Web.HttpContext.User" /> property is null, the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> sets the <see cref="P:System.Web.HttpContext.User" /> property to a <see cref="T:System.Security.Principal.GenericPrincipal" /> object that contains no user information. </para>
<para>If the authentication module sets the <see cref="P:System.Web.HttpResponse.StatusCode" /> property to 401, the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> will render an access-denied error page. If the value of the <see cref="P:System.Web.HttpResponse.StatusCode" /> property is set to a value greater than 200, the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> object will end the request. In that case, only HTTP modules that subscribe to the <see cref="E:System.Web.HttpApplication.EndRequest" /> event are called prior to the completion of the current request.</para>
<para>The <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> exposes an <see cref="E:System.Web.Security.DefaultAuthenticationModule.Authenticate" /> event. You can use this event to provide a custom <see cref="T:System.Security.Principal.IPrincipal" /> object for the <see cref="P:System.Web.HttpContext.User" /> property of the current <see cref="T:System.Web.HttpContext" /> instance. The <see cref="E:System.Web.Security.WindowsAuthenticationModule.Authenticate" /> event is accessed by specifying an event named <system>DefaultAuthentication_OnAuthenticate</system> in the application's Global.asax file.</para>

<para>The <see cref="E:System.Web.Security.DefaultAuthenticationModule.Authenticate" /> event is raised after the <see cref="E:System.Web.HttpApplication.AuthenticateRequest" /> event. It is used to ensure that the <see cref="P:System.Web.HttpContext.User" /> property of the current <see cref="T:System.Web.HttpContext" /> instance is populated with an <see cref="T:System.Security.Principal.IPrincipal" /> object.</para>
<para>You can access the <see cref="E:System.Web.Security.DefaultAuthenticationModule.Authenticate" /> event of the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> class by specifying a subroutine named <system>DefaultAuthentication_OnAuthenticate</system> in the application's Global.asax file. </para>
<para>You can use the <see cref="P:System.Web.Security.DefaultAuthenticationEventArgs.Context" /> property of the <see cref="T:System.Web.Security.DefaultAuthenticationEventArgs" /> object in the <system>DefaultAuthentication_OnAuthenticate</system> event to set the <see cref="P:System.Web.HttpContext.User" /> property of the current <see cref="T:System.Web.HttpContext" /> instance to a custom <see cref="T:System.Security.Principal.IPrincipal" /> object. If you do not specify a value for the <see cref="P:System.Web.HttpContext.User" /> property, the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> sets the <see cref="P:System.Web.HttpContext.User" /> property of the <see cref="T:System.Web.HttpContext" /> instance to a <see cref="T:System.Security.Principal.GenericPrincipal" /> object that contains no user information.</para>
<para>The <system>DefaultAuthentication_OnAuthenticate</system> event is raised after the <see cref="E:System.Web.HttpApplication.AuthenticateRequest" /> event and before the <see cref="E:System.Web.HttpApplication.AuthorizeRequest" /> event.

Be sure that the user name you set during the <system>DefaultAuthentication_OnAuthenticate</system> event is considered when you specify the <format type="text/html"><a href="2d3d9bf6-f914-4c30-ad03-32eea98fa612">authorization</a></format> section in your configuration.</para>

<para>If the Web application is running in IIS 7.0 in Integrated mode, the <see cref="E:System.Web.Security.DefaultAuthenticationModule.Authenticate" /> event of the <see cref="T:System.Web.Security.DefaultAuthenticationModule" /> is not raised. If the mode attribute of the <format type="text/html"><a href="27bc0ba9-f23a-45f3-ae42-dbe7916e3ee2">authentication</a></format> configuration element is set to "None" and the application subscribes to the <see cref="E:System.Web.Security.DefaultAuthenticationModule.Authenticate" /> event, a <see cref="T:System.PlatformNotSupportedException" /> error is raised. In this scenario, to receive authentication notification, subscribe to the <see cref="E:System.Web.HttpApplication.AuthenticateRequest" /> event of the <see cref="T:System.Web.HttpApplication" /> instance.
