Windows集成验证
　　集成 Windows 身份验证可以使用 NTLM 或 Kerberos V5 身份验证，当 Internet Explorer 试图设为集成验证的IIS的资源时，IIS 发送两个 WWW 身份验证头，Negotiate 和 NTLM。
　　客户端IE认识Negotiate头，将选择Negotiate头，之后IE可以选择NTLM 或 Kerberos两种验证方式。
　　如果客户端不认识Negotiate头，只能选择NTLM头，就只能使用NTLM验证方式。
　　现在IE使用的版本一般都在5.0以上，所以现在可以认为IE客户端都能识别Negotiate 头。
　　所以本文只考虑IE接受Negotiate头，分别使用NTLM 或 Kerberos两种验证的情况。
　　
1、 NTLM验证过程
1.1.    客户端选择NTLM方式
　　如果IE选择了NTLM验证，IE就会在发送到IIS的请求中加入一个Authorization: Negotiate头，内容为：

Authorization: Negotiate NTLMSSPXXXXXXXXXXXXXXXXX

　　蓝色部分在实际中是经过base64编码的，其中“NTLMSSP”表示是NTLM验证的请求，后面的“XXXXXXXX”部分是二进制的数据，告诉服务器，客户端现在选择了NTLM验证，请服务器发送质询码给客户端。
1.2.    服务端返回质询码
　　服务器在返回无授权访问的http回应的头部加入Authorization: Negotiate头，内容为：

Authorization: Negotiate NTLMSSPXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

　　服务器返回的“XXXXXXXX”部分中含有一个八字节的质询码。
1.3.    客户端加密质询码再次发送请求
　　客户端使用客户端帐号的密码派生出来的8字节DESkey使用DES算法加密收到的质询码。连同客户端帐号的用户名发送到服务端，形式还是这样：

Authorization: Negotiate NTLMSSPXXXXXXXXXXXXXXXXX

　　这里的“XXXXXXX”部分包含了加密后的质询码和客户端用户名，用户名在其中以明码形式存在。
1.4.    服务端验证客户端用户和密码
　　服务端收到用户名后，先查验本机是否有这个用户，如果没有直接返回没有授权的http回应。
　　如果有这个用户，就用这个用户的密码派生出来的8字节DESkey使用DES算法加密发给客户端的那个8字节的质询码，然后跟收到客户端发送来的加密后的质询码比较，如果不相同，表示客户端输入密码不正确看，返回没有授权的http回应；如果相同，就表示客户端输入这个用户的密码正确，验证通过，返回客户端请求的资源。
　　
2、 Kerberos验证过程
2.1.    客户端选择Kerberos验证
　　如果客户端选择了Kerberos验证，客户端直接在请求头中加入Authorization: Negotiate头，内容为：

Authorization: Negotiate XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

　　其中“XXXXXXXXXX”包含了客户端登录用户的身份验证票（登录时域中的票据服务器发放的标识此登录用户身份的票据，其中不包含用户的密码）。
2.2.    服务端验证身份验证票
　　服务器验证用户验证票，如果有效的票据，服务端能据此获得用户的用户名，并验证用户的有效性。验证通过后，服务端返回客户端请求的资源。
　　
　　但是客户端IE何时选择NTLM 、合适选择Kerberos呢？下面通过一系列的测试来找出答案。
　　
　　分服务器和客户端在域不在域两种情况测试。
　　
3、 客户端和服务器都不在域中

测试环境为服务器和客户端机器在同一个局域网中，但是都不在域中。客户端IE请求服务端IIS的一个页面default.aspx。

IIS服务端设置：

l         不启用匿名访问

l         只启用集成windows身份验证

　　这个环境下又分为下面几种情况：
3.1.    客户端用ip地址访问服务
3.1.1.    客户端IE申请页面

客户端IE浏览器的地址栏上输入要访问的URL，就会向服务端发送一个GET请求：

GET /wstest/default.aspx HTTP/1.1

Accept: */*

Accept-Language: zh-cn

UA-CPU: x86

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; MAXTHON 2.0)

Host: 192.168.1.13:81

Connection: Keep-Alive

3.1.2.    服务端返回无授权回应

服务端设置了禁用匿名访问，只允许windows验证，所以服务端返回了无授权回应：

HTTP/1.1 401 Unauthorized

返回的http头中还包括的:

WWW-Authenticate: Negotiate

WWW-Authenticate: NTLM

这两个头表示服务端只接受集成windows验证方式

HTTP/1.1 401 Unauthorized

Content-Length: 1327

Content-Type: text/html

Server: Microsoft-IIS/6.0

WWW-Authenticate: Negotiate

WWW-Authenticate: NTLM

X-Powered-By: ASP.NET

Date: Sun, 11 Nov 2007 12:28:29 GMT

3.1.3.    客户端选择NTLM验证，要求输入用户名密码，请求质询码

客户端通过Authorization: Negotiate NTLMSSPXXXX 头告诉服务器，客户端要求NTLM验证，请求服务端发送质询码。

GET /wstest/default.aspx HTTP/1.1

Accept: */*

Accept-Language: zh-cn

UA-CPU: x86

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; MAXTHON 2.0)

Host: 192.168.1.13:81

Connection: Keep-Alive

Authorization: Negotiate TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFAs4OAAAAD3==

3.1.4.    服务器返回质询码

服务端收到客户端的请求，发送一个八字节的质询码。

HTTP/1.1 401 Unauthorized

Content-Length: 1251

Content-Type: text/html

Server: Microsoft-IIS/6.0

WWW-Authenticate: Negotiate TlRMTVNTUAACAAAAEgASADgAAAAFgoqii7rzphzu6mEAAAAAAAAAAFwAXABKAAAABQLODgAAAA9CAEkAWgBUAEEATABLAFIAMgACABIAQgBJAFoAVABBAEwASwBSADIAAQASAEIASQBaAFQAQQBMAEsAUgAyAAQAEgBiAGkAegB0AGEAbABrAFIAMgADABIAYgBpAHoAdABhAGwAawBSADIAAAAAAA==

X-Powered-By: ASP.NET

Date: Sun, 11 Nov 2007 12:29:44 GMT

3.1.5.    客户端发送使用前面输入账户的密码加密后的质询码

客户端IE收到质询码后，使用根据一定的规则从登录用户密码派生出的8字节的key对质询码进行DES加密，加密后的质询码和用户名明码连同页面请求一起发送到服务端。

GET /wstest/default.aspx HTTP/1.1

Accept: */*

Accept-Language: zh-cn

UA-CPU: x86

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; MAXTHON 2.0)

3.1.6.    服务端验证通过，返回资源

服务端收到用户名和加密后的质询码后，根据用户名查找服务器上此用户的密码，按照客户端同样的方法加密质询码，然后跟收到客户端返回的质询码，如果一致，则说明用户名和密码都一致，验证通过，返回客户端IE请求资源。如果不对，再次返回无授权http回应。

3.2.    客户端用机器名访问服务器，登录用户名/口令跟服务器不匹配

这种情况，客户端用服务器名访问服务器，但是客户端登录系统的用户跟服务器上的用户名和密码不匹配，也就是要么服务器上没这个用户，要么就是服务器这个用户的密码跟客户端这个用户的密码不一样。

4、 客户端和服务器都在同一域中

服务器和客户端机器在同一个局域网中，并同在一个域中。客户端IE请求服务端IIS的一个页面iisstart.htm。

IIS服务端设置：

l         不启用匿名访问

l         只启用集成windows身份验证

这样的环境下又范围以下几种情况：

4.1.    客户端用机ip访问服务器
4.1.1.    客户端IE申请页面

GET /iisstart.htm HTTP/1.1

Accept: */*

Accept-Language: zh-cn

4.1.2.    服务端返回无授权回应
　　IIS的设置不允许匿名访问，只能windows验证，所以发送401无授权回应，同时发回Negotiate和NTLM两个身份验证头让客户端选择。

5、 集成验证总结
5.1.    客户端以ip地址访问服务器
　　不管客户端跟服务器是否在域、也不管客户端是否以域帐号登陆，只要客户端以ip地址访问服务器，那么客户端就会选择NTLM方式验证，并且不会直接发送客户端登录用户的用户名和密码给服务器，而是会弹出一个对话框要求用户输入用户名和口令，然后发送到服务端验证。

您可以避免在使用 IP 地址或名称中包含句点的企业内部网服务器上出现这种提示，方法是，在 Internet Explorer 的“本地 Intranet”设置中，列出包含 IP 地址的服务器，或是列出包含句点的服务器名称。可以通过依次单击“工具”、“Internet 选项”、“本地 Intranet”、“站点”、“高级”来访问“本地 Intranet”设置部分。然后在“将该网站添加到区域中”输入 http://127.0.0.1 或其他相关站点的 URL。

　　
　　下面总结的都是在客户端以机器名访问服务器的情况。
5.2.    服务器在域，客户端以域帐号登陆
　　如果客户端的机器在域中，同时登陆用户又是以域用户登录，那么IE选择Kerberos验证方式。
5.3.    其他情况IE都选择采用NTLM验证方式。
　　出来上述的两种情况，其他情况，客户端都选择NTLM验证，并首先尝试把登录客户端用户的用户名和密码传送给服务器验证，如果验证通过了，被直接授权访问；如果验证没通过，客户端弹出对话框要求输入用户名和密码，然后再传送到服务端验证，直到验证通过。

　　集成 Windows 身份验证Kerberos的验证方式是 Intranet 环境中最好的身份验证方案，在这种用户拥有 Windows 域帐户，Kerberos验证不在网络上传递用户密码，只用传送一个用户验证票。NTLM要传送用户的密码，但是密码经过处理后派生出一个8字节的key加密质询码，也是比较安全的。

四、  基本身份验证

客户端IE请求服务端IIS的一个页面iisstart.htm。

IIS服务端设置：

l         不启用匿名访问

l         只启用基本身份验证

1、 客户端IE申请页面

GET /iisstart.htm HTTP/1.1

Accept: */*

Accept-Language: zh-cn

UA-CPU: x86

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727; MAXTHON 2.0)

Host: logs:81

Connection: Keep-Alive

2、 服务端返回无授权回应，并告知客户端要求基本身份验证
　　服务端设置的基本身份验证，所以这里返回的无授权回应的http头中包含 WWW-Authenticate: Basic 头，告诉客户端，服务端要求的是基本身份验证

HTTP/1.1 401 Unauthorized

Content-Length: 1327

Content-Type: text/html

Server: Microsoft-IIS/6.0

WWW-Authenticate: Basic realm="logs"

X-Powered-By: ASP.NET

Date: Mon, 19 Nov 2007 06:15:57 GMT

3、 客户端弹出对话框要求输入用户名和密码

GET /iisstart.htm HTTP/1.1

Accept: */*

Accept-Language: zh-cn

UA-CPU: x86

Accept-Encoding: gzip, deflate

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727; MAXTHON 2.0)

Host: logs:81

Connection: Keep-Alive

Authorization: Basic YWRtaW5pc3RyYXRvcjpzemJ0aUAxMDA1

　　客户端把用户名和密码转换成base64编码后，直接发送到服务端。

发送到服务器的“Authorization: Basic”头里面的“YWRtaW5pc3RyYXRvcjpzemJ0aUAxMDA1”部分就是用户的用户名和密码，经过base64解码后是这样的：administrator:szbti@1005

4、 服务端验证通过，返回资源
