Access AFP shares with no login/password

Using the Beta4 I want to connect to my ReadyNAS NV+ where AFP is turned on. I usually connect to it with guest access as I have no users set up on the NAS for AFP. With the new Media Player it does not seem to be possible to set up a share without login/password. Am I missing something here or is this a missing feature?

Thanks

I found that I had to use the username and password that I use to get into the NAS box's web based editor to add my NAS as a source.
