Ok so I found this thread (
https://groups.google.com/forum/?fromgroups=#!topic/constellio/ZQuxw0fiSWk) and when I added the credentials to a user I'm able to see results now. Is it possible for unauthenticated users to get results? One post mentions this was going to possibly be added in v1.2 but that doesn't look like the case unless there is another option I'm not seeing.
I don't know if I should open another thread, but is it also possible to return an "smb://" link in the results instead of "file://"? I'd like to have a clickable link that opens the file in Safari on OS X.
