Retrieve user's Windows logon using PHP/Apache

[mikkelbo]

Hi

I am looking for a way to grab the Windows logon information(from Win NT/2000) in PHP.

I have seen a few posts describing how to do it with IIS, but I am using Apache. (And PHP 4.2.2).

Is it possible to retrieve the appropriate http header without fancy server add-ons, i.e. using default PHP4 (with changes to php.ini) and Apache?
