Detecting authenticated username in PHP

Hi,
Hope someone can help.

I've got an internal website running on Linux (Ubuntu),Apache 2, MySQL 4.x, PHP4.x that is using mod_ldap.so
mod_auth_ldap.so to do user authentication from an Active Directory LDAP server.

See http://www.experts-exchange.com/Operating_Systems/Linux/Q_21477850.html for my recent post on this.

My question is this - how can I pick up the authenticated username in a PHP4 script? Must I make some changes to Apache, or PHP? Must I use some PHP module?

Can anyone help?
Many thanks,
Ben.

See http://de3.php.net/manual/en/features.http-auth.php

Regardless, REMOTE_USER can be used to identify the externally-authenticated user. So, you can use $_SERVER['REMOTE_USER'].

Hi hernst42,

Many thanks for this. This seemed to work perfectly. One follow up question - do you know how long the session lasts for? Or where one can control that kind of information? Is it an apache setting?

Thanks Ben.

No its a thing of the browser which send the user-id and password until the browser is closed to the same pages and directory below the fist auth-page. So there is no session for the external user-authentication.
