How to get user name using Windows authentication in asp.net?
提问by user2148679
I want to get user name using Windows authentication
我想使用 Windows 身份验证获取用户名
Actually I implemented "Sign in as different user",when click this button Windows security will appear there we can give credentials.
实际上我实现了“以不同用户身份登录”，当单击此按钮时，Windows 安全性将出现在那里，我们可以提供凭据。
In that time if I give some other credential it is taking current user name only. How to get that given credential user name from windows security?
在那个时候，如果我提供一些其他凭据，它只会使用当前用户名。如何从 Windows 安全中获取给定的凭据用户名？
Host application in IIS then anonymous authentication has disabled and windows authentication was enabled.
IIS 中的主机应用程序然后禁用匿名身份验证并启用 Windows 身份验证。
web.config:
网络配置：
<system.web>
<compilation debug="true" targetFramework="4.0" />
<identity impersonate="true"/>
<authorization>
<allow users="*"/>
<deny users="*"/>
</authorization>
</system.web>
<system.webServer>
<directoryBrowse enabled="true" />
<security>
<authentication>
<anonymousAuthentication enabled="false" />
<windowsAuthentication enabled="true" />
</authentication>
</security>

I think because of the below code you are not getting new credential
我认为因为下面的代码你没有得到新的凭证
string fullName = Request.ServerVariables["LOGON_USER"];
You can try custom login page.
您可以尝试自定义登录页面。

You can get the user's WindowsIdentityobject under Windows Authentication by:
您可以通过以下方式在 Windows 身份验证下获取用户的WindowsIdentity对象：
WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;
and then you can get the information about the user like identity.Name.
然后您可以获取有关用户的信息，例如identity.Name。
Please note you need to have HttpContext for these code.
请注意，您需要为这些代码设置 HttpContext。

This should work:
这应该有效：
User.Identity.Name
Identityreturns an IPrincipal
Identity返回一个 IPrincipal
Here is the link to the Microsoft documentation.
