APC UPS problem on OS X

[josh hough]

I recently got a new APC Back-UPS ES 500 for an OS X 10.2.6 machine and 
installed the Jaguar-compatible version of the APC PowerChute software. 
When I test the system by unplugging the UPS, PowerChute somewhat 
gracefully shuts down the machine.  However, this only works when a user is 
logged in (it can be any user).  Most of the time nobody is logged into 
this machine.  In that case, the UPS reaches the end of its battery life 
and suddenly cuts the power, resulting in a *very* ungraceful hard shutdown.

Isn't there supposed to be a daemon running in the background all the time, 
waiting for a signal from the UPS?  The System Preferences pane for APC 
indicates nothing to that effect, and I can't find any relevant 
documentation on their site.  Thanks for any clues.
