How do I retrieve the user information of a user authenticated with Apache's mod_ldap?

I have LDAP authentication working with Apache. Now I need to know how I can get what user logged in with PHP. Is it even possible? Do I have to do the authentication in PHP to store the user name?

Solution

I am not sure if it's the same with mod_lsap, but when you authenticate using Apache, the username and password are stored in the $_SERVER's superglobals.

$_SERVER['PHP_AUTH_USER']
$_SERVER['PHP_AUTH_PW']
