Debian :: Retrieve Remote User

I have a server using ldap. I installed Debian with an Apache webserver with PHP and MySQL support.This server will be used for intranet so I want to know what the REMOTE_USER variables is.Looking at the phpinfo does not give any reference to the REMOTE_USER. REMOTE_ADDR is no problem but does not give me the user using the computer.I've installed libapache2-authenntlm-perl with apt-get and adjusted my /etc/apache2/sites-enabled/000-default file with the following:

Code: Select all<Directory "/var/www/intranet">
    PerlAuthenHandler Apache2::AuthenNTLM
    AuthType ntlm,basic
    AuthName mycompany
    require valid-user
    PerlAddVar ntdomain "server.domain.be server"
    PerlSetVar defaultdomain server.domain.be
    PerlSetVar splitdomainprefix 1
</Directory>

where server is my servername and domain is my domainname.The problem after reloading apache2 is that I get the following message: This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.When I delete the AuthType, AuthName and require line it loads the webpage but without the REMOTE_USER variable.

It is not ment to ask for a password or username, just to get the username used to log in in the Windowsenviroment that visits the webpage on this Debian.
