Hi Lorenzo, I've faced the same issue when trying to leave the "Security mode:" blank. Guacamole has started prompting for credentials when connecting to RDP machines as soon as I've switched it to "Any"; For me this works for Windows machines older than Server 2008R2 as well as newer(where NLA is enforced by default)!
