Changing Security Setting of Screensaver in 10.5

Hello

i am trying to write a toggle for the security setting of the
screensaver in Mac OS X.
I know i could do that by User-Interface scripting but thats not the
way i want to solve my issue.

From Sys-Prefs point of view the following code-snippet seems to work,
but it seems just to change the User-Interface -> so if the checkbox
is selected or not -> without doing what a user would expect.

Code-Snippet Start:

-- check setting
set output to do shell script "defaults -currentHost read
com.apple.screensaver askForPassword -int"
--
if output is "0" then
do shell script "defaults -currentHost write
com.apple.screensaver askForPassword -int 1"
tell application "System Events"
set value of property list item "askForPassword" of
property list file plistFile to 1
end tell
-- quick debug message
display dialog "pw enabled"
else
do shell script "defaults -currentHost write
com.apple.screensaver askForPassword -int 0"
tell application "System Events"
set value of property list item "askForPassword" of
property list file plistFile to 0
end tell
-- quick debug message
display dialog "pw disabled"
end if

-- start the screensaver to check if the setting which worked for
the UI in Sys-Prefs does what i would expect to do.
tell application "ScreenSaverEngine"
activate
end tell

Code-Snippet End:

Reached that point i started to take a look on fseventer which showed
me another plist to check in
/Users/myusername/Library/Preferences/ByHost/
com.apple.screensaver.SOMECRYTIC_MACHINE_SPECIFIC_THING_HERE_I_GUESS
which contains the askForPassword element too.

Im somehow wondering what i dont understand here and why my user-
interface displays something which is does not do in case of
screensaver start.

I hope my description is ok, if not feel free to ask and i'll try to
add as muchdetails as needed.
My target is to use this applescript code in a small Cocoa project as
part of a NSAppleScript if that matters.


Best regards
fidel

I understand your description, but I hope it's not possible to do what you
want, since this would allow someone to mess with admin settings without
knowing the admin password.
