Finder Auto Connect to AFP share

I'm using Ubuntu as an AFP server (c/o netatalk) and everything is working fine as far as seeing the server in Finder and connecting to the shares. Whenever I first select the server in Finder, it briefly says 'Connecting...' and about 3 seconds later it says 'Connection Failed'. Obviously Finder is attempting to connect to the share and my question is whether it's trying using the current account credentials or is it trying using guest credentials. I would like to automatically connect without the need of selecting 'Connect As...' and entering my credentials over again. I'm using the same credentials on both the server (Ubuntu) and client (Leopard). Is this possible?

Thanks in advance,
