So in ARD UNIX as root, I do
(where the blank space is 3 tabs)

cp /etc/authorization /Users/Shared/authorization.$$

sed 's;^			<string>The owner or any administrator can unlock the screensaver.</string>$;			<string>(Use SecurityAgent.) The owner or any administrator can unlock the screensaver.</string>;' /Users/Shared/authorization.$$ >/etc/authorization

diff /Users/Shared/authorization.$$ /etc/authorization
