I noticed an A and AAAA lookup in ethereal
and the ipv6 address was used, which is good because I've enabled it

oops, forgot to mention something..

the ipv6 address, which is being used by default, is attached to a server that 
gives a Connection Refused error
that is why the ftp function won't work. it uses ipv6 fine, but the server 
refuses.
the ipv4 ip that is returned by the gethostbyname() in the script will also 
return the correct and most used ip, which is good

some time ago there was a problem with nl3.php.net, which ended up with an 
incorrect setup for ipv6, the ipv4 site worked fine

I've contacted the openldap.org team, I hope they can fix this issue because 
it should not be needed, but I noticed that after some more research.
