Error reporting did the trick! "Call to undefined function: ldap_connect()" -> Had to install php5-ldap. Problem solved.

Thanks for your reply! Doesn't it have to be $port = 1337? I'm running Linux on my local pc. Nmap for both port 389 and 1337: Server 2 has no external ip, so I used his internal ip. Nmap scan report for ip_server_2 Host is up. PORT STATE SERVICE 389/tcp filtered ldap Nmap scan report for ip_server_2 Host is up. PORT STATE SERVICE 1337/tcp filtered waste

You mean on my local pc? Server 2 is not reachable from the outside. Also, nmap is not installed on server 1 and server 2.

Thanks for your reply!

Hi I have the next set up: A server (1) that is reachable from the internet and an internal server (2) that is not reachable externally, but can be reached through server 1. Now. When I run next script on server 1, everything works. 'startsuccess!' is printed. <?php echo "start"; $host = 'server2'; $port = '389; $ds = ldap_connect($host, $port); echo "success!"; ?>When I run this on my local pc, it doesn't work. I forward port 389 to port 1337. This tunnel should work, because portforwarding of other ports (like 22) work. This is the script I run locally: <?php echo "start"; $host = 'localhost'; $port = '1337; $ds = ldap_connect($host, $port); echo "success!"; ?>Only 'start' is printed out. Am I doing something wrong, or do I have to forward more ports? Thanks!
