总结asp.net的身份验证方式
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--> <location path="register.aspx"> <system.web> <authorization> <allow users="?" /> </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. --> <compilation debug="true"/> <!-- The <authentication> section enables configuration of the security authentication mode used by ASP.NET to identify an incoming user. --> <authentication mode="Forms"> <forms name="auth" loginUrl="login.aspx" timeout="30" protection="All" path="/"></forms> </authentication> <!--禁止匿名用户登录--> <authorization> <deny users="?"/> </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> 2)登录页面代码

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。
