Question

我是Active Directory的新手。

我有一个VBA Excel加载项，当且仅当运行它的计算机当前登录到Active Directory时才能运行，无论是在本地还是通过VPN。

知道域名，我如何检索当前登录用户的用户名？

谢谢！

Answer 1

我知道这有点晚了，但去年我去了地狱找到以下代码，可以返回用户名（“fGetUserName（）”）或全名（“DragUserName（）”）。您甚至不需要知道广告/直流地址..

希望这对咨询此问题的任何人都有帮助。

Answer 2

已编辑：如果我理解你的情况，那么你可能会采取错误的方式。

当您的应用启动时，您可以针对用户只能看到它们是否已连接到您的网络，是否登录到本地网络或是否通过VPN连接的计算机执行简单ping操作

如果他们已经可以访问您的本地网络，则意味着他们已经针对任何机制进行了身份验证，无论是Active Directory还是其他内容，这意味着他们“已登录”。

另外，Active Directory本身并不知道是否有人登录。你无法做到这样的事情：

ActiveDirectory.getIsThisUserLoggedIn("username");

Active Directory仅充当用户元数据，安全性和身份验证的机制。

Answer 3

试试这个

MsgBox Environ("USERNAME")

Answer 4

此函数返回已登录用户的全名：

Function UserNameOffice() As String
    UserNameOffice = Application.UserName
End Function

如何从VBA获取当前登录的Active Directory用户名？
