Where does Flash Player store its trusted site list on Linux?

Question

Specifically, we have a fairly large network of HP thin clients running HP ThinPro (a variant of Debian) with Adobe Flash Player pre-installed. We have a new application coming to the network which will make use of the camera. Flash is doing its job and asking for permission to use the camera every time the page loads. Unfortunately, it is not giving us the options to add the site/domain to its trusted list to not ask for permission every time (perhaps due to the locked file system, not certain why the advanced options aren't coming up). In any case, we're trying to find where Flash Player stores this information so we can go edit it manually in the file system (we can unlock it temporarily, make the change, and re-lock, then capture the system image for later deployments). We've not been able to find where it's located. Any thoughts or ideas where to look?

I checked this out with webcamtoy.com on my Ubuntu workstation using Google Chrome.

The data was recorded here

/home/rbabchis/.config/google-chrome/Default/Pepper Data/Shockwave Flash/WritableRoot/#SharedObjects/UL8AK5CB/macromedia.com/support/flashplayer/sys/#webcamtoy.com/settings.sol

It contained

$ hexdump -C settings.sol

It also created these files that don't seem to be very useful
