LinuxQuestions.org - NTLM on new Apache 2.4 in Debian 8.4

Hi,
I've recently installed the new Debian 8.4 with Apache 2.4.10 with the purpose of installing a intranet.
One of the things the intranet must contain is the retrieval of the username through $_SERVER['REMOTE_USER'] from the Windows PC's that connect to this server. The package mod_auth_ntlm_winbind was installed along with the following /etc/apache2/httpd.conf file:

Code:

DirectoryIndex index.php index.html index.htm KeepAlive on <Directory "/var/www/html/test">

  PerlAuthenHandler "Apache2::AuthenNTLM"

  AuthType ntlm,basic

  AuthName "NTLM Authentication"

  require valid-user

  PerlAddVar ntdomain "my_dom 10.52.28.220"

  PerlSetVar defaultdomain "my_dom"

  PerlSetVar splitdomainprefix 1

  PerlSetVar ntlmdebug 0

  PerlSetVar ntlmauthorative off

  PerlSetVar ntlmsemkey 0

  PerlSetVar ntlmsemtimeout 1

</Directory>

How can I solve this easily?
I'm a newby so don't make it too hard [;)]

Thanks in advance!

[EDIT]
The module libapache2-authenntlm-perl was installed also but the parameter REMOTE_USER was not found in the phpinfo.
