[launchd-dev] launchd & launchctl Aqua session type on OSX Tiger

[James Mead]

I have a script which I can successfully schedule using on OSX Leopard 
as follows :-

launchctl load -w -S Aqua com.floehopper.script
Apparently I need the Aqua session type because the script accesses the 
keychain using the SecKeychainFindGenericPassword function. If I don't 
set the session type to Aqua, I get a errSecInteractionNotAllowed 
"Interaction with the Security Server is not allowed" error (-25308).

However, I also want to schedule the script on OSX Tiger, but the 
session type -S option is not available for launchctl.

I've tried calling the SecKeychainSetUserInteractionAllowed function 
with the state parameter set to false, but then I end up with a 
errSecAuthFailed "Authorization/Authentication failed" error (-25293).

Does anyone have any ideas how I might get this working on OSX Tiger?
