I am not a member of the nut group (it is empty on my system) and everything is
working for me except the UPS does not turn off, still trying to figure this
out.  Because of the way Ubuntu handles the USB to serial interface I did have
to put the nut user in the dialout group.

I did put my userid and password in two of the .conf files.

Look at chapter 6 of the "Network UPS Tools User Manual", url is in my reply
above.  That is what I had to do to get all the .conf entries correct.
