./configure  --enable-force-cgi-redirect --with-gd --with-ttf --with-mysql --disable-display-source --with-config-file-path=/etc --with-ldap

<? include "categories.inc"; ?> 

and "categories.inc" starting with:

<TD>
<?   $dbhost="XXXXXX";
   $dbname="XXXX";
   $dbuser="XXXXX";
   $dbpwd="XXXXX";
   print "$REMOTE_USER";
   $mysql=mysql_connect($dbhost, $dbuser, $dbpwd);
   mysql_select_db($dbname, $mysql);
