New iMacs Monitors automaticlly de-calibrating

We have new 27 inch iMacs in our multi-user student labs with color managed monitors
The new iMacs (v12,5) however now has an ambient light sensor.

Users logging in for the first time on these iMac's always have the default for the new "Automatically adjust brightness (of monitor) as ambient light changes" check box ON, in the monitor control preferences. The problem this causes In our low-light level lab is that this auto feature then moves the brightness of the monitor down from our 120 cdm setting every time a new user logs on.

Our IT Tech is still trying to find a way to have the auto brightness off as a default for new users but has so far been unsuccessful.
Has anyone been able to solve this?



Note:
Students are given localized accounts on our iMacs that self erase after 8 day of non-use
Running Mac OS 10.6.8
