asp.net提供了3种认证方式: windows身份验证, Forms验证和Passport验证.
windows身份验证: IIS根据应用程序的设置执行身份验证.要使用这种验证方式,在IIS中必须禁用匿名访问.
Forms验证:用Cookie来保存用户凭证,并将未经身份验证的用户重定向到自定义的登录页.
Passport验证:通过Microsoft的集中身份验证服务执行的,他为成员站点提供单独登录和核心配置文件服务.
一. 配置windows身份验证
1)配置IIS设置
2)设置Web.config
<system.web>
<authentication mode = "Windows">
<!--通知操作系统将当前登录的用户的信任书传递给浏览器-->
<authorization>
<!--禁止匿名用户访问-->
<deny users = "?"/>
</authorization>
</system.web>
二.配置Forms身份认证
1)配置web.config
<?xml version="1.0"?>
<!--
Note: As an alternative to hand editing this file you can use the
web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.
A full list of settings and comments can be found in
machine.config.comments usually located in
\Windows\Microsoft.Net\Framework\v2.x\Config
-->
<configuration>
<appSettings/>
<connectionStrings/>
<!--允许匿名用户登录register.aspx页-->
<locationpath="register.aspx">
<system.web>
<authorization>
<allowusers="?"/>
</authorization>
</system.web>
</location>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilationdebug="true"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authenticationmode="Forms">
<formsname="auth" loginUrl="login.aspx" timeout="30" protection="All" path="/"></forms>
</authentication>
<!--禁止匿名用户登录-->
<authorization>
<denyusers="?"/>
</authorization>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>

</customErrors>
-->
</system.web>
</configuration>
2)登录页面代码

19 {
20 FormsAuthentication.RedirectFromLoginPage(this.TextBox1.Text,false);

三.配置Passport身份认证
需要安装Passport Software Developer Kit.这种认证方式适合于跨站之间的应用,用户只有一个用户名和密码可以访问任何成员站。
