單點登錄（Single Sign On），簡稱為 SSO，是目前比較流行的企業業務整合的解決方案之一。SSO的定義是在多個應用系統中，用戶只需要登錄一次就可以訪問所有相互信任的應用系統。
asp.net跨域單點登錄分為：
1、跨子域單點登錄。如 blog.a.com 和 info.a.com 這2個站點同屬一個主域.a.com，實現跨子域單點登錄很簡單，可以利用cookie，設置Domain為”.a.com'即可，這裡就不再贅敘。
2、完成跨域單點登錄。如 www.a.com www.b.com 這2個站點之間實現共享一個身份驗證系統，只需在一處地方登錄，下面主要談下這種方式的實現方法。
asp.net 跨域單點登錄實現原理：
當用戶第一次訪問web應用系統1的時候，因為還沒有登錄，會被引導到認證中心進行登錄；根據用戶提供的登錄信息，認證系統進行身份效驗，如果通過效驗，返回給用戶一個認證的憑據；用戶再訪問別的web應用的時候就會將這個Token帶上，作為自己認證的憑據，應用系統接受到請求之後會把Token送到認證中心進行效驗，檢查Token的合法性。如果通過效驗，用戶就可以在不用再次登錄的情況下訪問應用系統2和應用系統3了。所有應用系統共享一個身份認證系統。認證系統的主要功能是將用戶的登錄信息和用戶信息庫相比較，對用戶進行登錄認證；認證成功後，認證系統應該生成統一的認證標志，返還給用戶。另外，認證系統還應該對Token進行效驗，判斷其有效性。 所有應用系統能夠識別和提取Token信息要實現SSO的功能，讓用戶只登錄一次，就必須讓應用系統能夠識別已經登錄過的用戶。應用系統應該能對Token進行識別和提取，通過與認證系統的通訊，能自動判斷當前用戶是否登錄過，從而完成單點登錄的功能。
比如說，我現在有3個分站點和1個認證中心(總站)。當用戶訪問分站點的時候，分站點會發Token到驗證中心進行驗證。驗證中心判斷用戶是否已經登錄。如果未登錄，則返回到驗證中心登錄入口進行登錄，否之則返回Token驗證到分站點，直接進入分站點。
如圖所示:
上面是實現單點登錄的原理圖，下面介紹下如何用asp.net實現跨域單點登錄：
一、新建網站 MasterSite,作為總站認證中心。配置web.config,采用form登錄驗證。
配置如下：
<authentication mode=”Forms”>
<forms name=”.AspxFormAuth” loginUrl=”Default.aspx” defaultUrl=”center.html” protection=”All” path=”/” timeout=”120”>
</forms>
</authentication>
<authorization>
<!--拒絕所有匿名用戶-->
<deny users=”?”/>
</authorization>
<authentication mode=”Forms”>
<forms name=”.AspxFormAuth” loginUrl=”Default.aspx” defaultUrl=”center.html” protection=”All” path=”/” timeout=”120”>
</forms>
</authentication>
<authorization>
<!--拒絕所有匿名用戶-->
<deny users=”?”/>
</authorization>
添加Default.aspx頁面，用來進行登錄。代碼如下：
HTML Code:
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”_Default” %>
<!DOCTYPE html PUBLIC ”-//W3C//DTD XHTML 1.0 Transitional//EN” ”http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml” >

代碼說明：驗證分站post過來的Token請求,如果用戶已經登錄，則創建認證中心發往各分站的 Token驗證，轉向分站，否之則返回登錄。若是直接登錄主站則轉向站點選擇頁面sitelist.aspx，選擇你要登錄的分站點。

配置web.config
<authentication mode=”Forms”>
<forms name=”.AspxFormAuth” loginUrl=”Default.aspx” defaultUrl=”center.html” protection=”All” path=”/” timeout=”60”>
</forms>
</authentication>
<authorization>
<!--拒絕所有匿名用戶-->
<deny users=”?”/>
</authorization>

最後效果如下：登錄總站後，各站點之間無需再登錄，可以互相訪問。
另外，注銷登錄後，訪問站點1 http://localhost/Site1/Default.aspx ,會自動跳轉到主站登錄頁面 http://localhost/MasterSite/Default.aspx ,同樣訪問站點2 http://localhost/Site2/Default.aspx 也會轉到主站登錄頁面。從主站登錄後，分別訪問站點1和站點2。
在IIS配置虛擬目錄MasterSite Site1 Site2，當然你也可以新建站點MasterSite Site1 Site2，修改hosts表
127.0.0.1 www.MasterSite.com
127.0.0.1 www.Site1.com
127.0.0.1 www.Site2.com
