Question

The users will only use IE, and within IE it can pass their credentials without being prompted to, if they are logged onto the domain controller.

What I want to know is, how do I go about grabbing their username?

I thought this would do the trick: $_SERVER['auth_user'];but no luck.

Just like this Can you get a Windows (AD) username in PHP?

But I don’t know what the code should look like this to capture/grab the user’s username

Any help is appreciated.

Answer 1

There is no way to solve the problem in php directly, but you can obtain the username with the help of javascript:

<script type="text/javascript">
<!--
var WinNetwork = new ActiveXObject("WScript.Network");
alert(WinNetwork.UserName);
//-->
</script> 

Just add some AJAX 😉
