Good.  One form of samba authentication requires that the samba users 
must be legitimate linux users as well. I was wondering if maybe 
something like that was going on here with nut.  Grasping at straws, you 

Here's my entire 'upsd.users' contents:
    password = mypassword
    allowfrom = local
    upsmon master

Here's my entire 'upsmon.conf' file (though I'm not sure how this comes 
in to play with upsc):
MONITOR cyber at localhost 1 nutmon mypassword master

Are there other entries I need to add? All I want to do at this point is 
verify that 'upsc cyber' will work.
