iis 7.5 dns windows身份验证页面用户身份不起作用

【中文标题】iis 7.5 dns windows身份验证页面用户身份不起作用【英文标题】：iis 7.5 dns windows authentication page user identity not working 【发布时间】：2011-06-23 00:06:09 【问题描述】：在 IIS 7.5 服务器中，我有一个网站 apps.mydomain.com。本网站的网站绑定为：
IP：全部未分配
端口：80
主机名：apps.mydomain.com
在 DNS 中有一个指向 apps.mydomain.com 的 IP 地址。浏览到此主机名时，站点正常。
我想从 asp.net 网络应用程序中获取当前 windows 登录的用户名。我启用了 Windows 身份验证并禁用了匿名。使用此 ASP.Net 代码进行测试：
Response.Write(Page.User.Identity.Name);
但是，浏览到 http://apps.mydomain.com/site/ 时，应用程序池标识显示为 Page.User.Identity.Name 值，而不是当前登录的窗口用户名。
如果我浏览到http://servername/site/，那么 Page.User.Identity.Name 将返回当前窗口登录的用户名。
在使用主机标头时，我还需要配置其他什么来获取当前窗口登录的用户名吗？
web.config：
<?xml version="1.0"?>
<configuration>
<system.web>
<authentication mode="Windows"/>
</system.web>
</configuration>
应用程序池配置（为简洁起见，省略了“处理程序”，限制为 30000 个字符）：

【问题讨论】：
您能否发布一个链接以下载您的应用程序池配置文件和 web.config 文件以更好地了解您的设置？应用程序池配置文件通常位于“C:\inetpub\temp\appPools\” 如果我通过 dns 条目的 IP 浏览 apps.mydomain.com 用户名是正确的。 尝试禁用匿名访问并启用 windowsAuthentication。它目前在您的配置文件中设置为 false。 我从终端服务器尝试过，并且从这里正常工作。不确定是什么或是否是我的机器上的某些东西在起作用。 我也有同样的问题 - 你解决了吗？ 【参考方案1】：将测试应用程序的应用程序池从“test”更改为“.NET 2.0 Apps”，因为您网站的根目录与测试应用程序的配置不同。 为“.NET 2.0 Apps”应用程序池正确设置了 Windows 认证，但我认为这不会影响“测试”应用程序池。
祝你好运
【讨论】：
【参考方案2】：很可能，因为 http://servername/site/ 正在工作，这是因为您正在解析到内部 DNS 服务器，因此 Windows Auth 为您启动。您是否尝试过在 web.config 文件中将身份验证方法显式设置为“Windows”？
<authentication mode="Windows" />
【讨论】：
以上是关于iis 7.5 dns windows身份验证页面用户身份不起作用的主要内容，如果未能解决你的问题，请参考以下文章
IIS 7.5 Windows 身份验证失败，除非代码文件共享给最终用户
使用 Silverlight 5、IIS 7.5 对 WCF 服务进行 Windows 身份验证
具有 Windows 身份验证的 IIS 7.5 Web 应用程序是不是要求最终用户具有文件权限？
使用 Powershell 3.0 切换 IIS 7.5 身份验证“匿名身份验证”？
