I'm working on an app in Mac OS X Mountain Lion that needs to access the private key of some of my certificates within the Keychain Access. Since this app is going to run on a server, I need to avoid the pop up dialog that requires the user to allow the app to access the private key:

I know that by clicking "Always Allow" the dialog won't popup anymore for that private key, the problem is that I will be working with different keys.
Thanks in advance,
Mikywan.
