It's difficult to say. If you have any custom network setups like a proxy or a 
firewall it's possible you need to make adjustments. Generally you would have 
a good idea about that. Quanta uses KIO slaves and you would use 
ftp://user@domain/path in a dialog for instance. As to not accepting 
passwords there are potentially different causes. The server you're accessing 
may be experiencing load and timing out. In the past KIO FTP had problems 
with servers set up to manage typical Windows clients which did not properly 
handshake. That means if you send a file the software assumes it got there 
and does not look for verification. This handshaking is in the protocol 
definition and integral to moving packets. Some servers were taking as long 
as half a second minimum to handle the handshake, which is really quite 
pathetic. Last I heard all the confirmed incidents of really bad handshaking 
were being handled correctly. If you can confirm that a software package that 
doesn't handshake works and KDE doesn't then you need to report this bug to 
kdelibs.

As a side rant, FTP is a poor choice for web hosting. When the web was a DARPA 
project or when it just exchanged information between universities it was 
good, but for supporting web sites it's not so good. For one thing it sends 
your password in clear text every time you make a request and for another 
nothing is encrypted. It's very easy to sniff an address and it's a walk in 
the park for the most amateur blackhat to gain access. Conversely SSH and SCP 
are very secure and usually available, certainly on any decent Linux based 
host. These can be handled with the fish:// protocol. Using ssh-keygen you 
can create passwordless keys and make access to remote sites like VPN.
