server {
    listen                127.0.0.1:9500;
    root                  /usr/share/nginx/html/nginx-mail-auth-ldap;
    index                 index.php index.html;

    location ~ \.php$ {
        include           fastcgi_params;
        fastcgi_param     SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param     PATH_INFO $fastcgi_path_info;
