''Automatically Discover Host and port'' doesn''t work?

We use Pandion to connect to our Wildfire server, I recently tried Spark and even though I have ‘‘Automatically Discover Host and Port’’ checked off it won’'t let me click ‘‘Login’’ until I fill out the server field. Pandion requires no configuration, it uses the service location records to find our server.

What do I have to do to get Spark to work without configuring anything?

Wow so this must really broken then if no one knows. Does anyone know if this it something on the list of future fixes?

I really dont think “Automatically Discover Host and Port” means what you think… I dont think there are any magic way for Pandion to find out what ip/domain to connect to by just typing the username…
