Drobo Share - Username & Password

Hi, just setup my DroboShare with netatalk installed. Can’t mount the DroboShare using afp. Keep asking for the Username & Password. I’m using a iMac with Snow Leopard OS. Anyone have any ideas the username & passwd?

As I know the drobo cann not be access afp, only smb - is it right?

As I understand it, if you install the BackMyFruitUp DroboApp, then the DroboShare will know how to talk AFP.
