If the sensors can connect to Kura only (i.e. they are on a private
network where you have deployed a Kura instance as a "gateway" to your
back end) then you will need to run a leshan server on Kura, yes. Kura
itself by default connects to an MQTT broker (not running on Kura but
usually in the back end) for transmitting data from sensors to back end
components (like Eclipse Kapua) and for receiving management messages.
If you want to be able to manage sensors from the back end as well then
you will need to implement a mapping from the protocol Kura uses with
the back end to/from LWM2M (what the leshan server on Kura uses to
manage the sensors).

Probably because nobody feels a desire to get it running :-) It's open
source, so if you feel that you need this then you should simply start
working on it and ask for advice on the Kura mailing list.
