Thanks for the help,
I tried that and I still couldn't seem to get it going.
I am just testing this stage and if it works I will set up a more permanent folder structure, so at this stage I manually created /etc/chromium/policies/managed
I download the example .JSON file from
http://www.chromium.org/administrators/policy-templatescopied it to /etc/chromium/policies/managed/chrome.json
chmod 777 on it so that everyone has full access while I am testing.
Opened Chromium, as the .json file has the homepage set to
www.chromium.com I was expecting that to be the homepage, but nothing seemed to come up.
Am I doing something wrong?
Thanks again.
