It's quite simple actually..

dig AAAA ftp.openldap.org
ftp.openldap.org.       3600    IN      CNAME   www.openldap.org.
www.openldap.org.       3600    IN      AAAA   
2001:4f8:3:ba:2e0:18ff:fe02:efec

$ php -r 
"var_dump(gethostbyname(gethostbyaddr('2001:4f8:3:ba:2e0:18ff:fe02:efec')));"
string(14) "204.152.186.50"

$ php -r "var_dump(gethostbyname('ftp.openldap.org'));"
string(14) "204.152.186.57"

my system and php tries to use ipv6, which is not strange these days, and 
therefor tried to connect to 204.152.186.50, which will return false for the 
ftp_connect() call.

my browser will only work with ipv4, making it connect to 204.152.186.57, 
which works fine.. and seems to work fine for others too.

I've ran the script on the three supported global.ent files, and none is 
giving ftp connect errors.
