I have the screen saver on my Mac password protected, but unlocking the screen saver does not unlock the login keychain. I know this because I get asked to unlock the login keychain shortly after unlocking the screensaver.
Yes, my login password and keychain password have been synchronized.
Yes, I've run Keychain First Aid and confirmed there are no problems.
The workaround is to change the Keychain Settings so the login keychain never automatically locks, but I'd prefer to have it lock automatically, especially on my laptop when it goes to sleep, but now with Mountain Lion and iCloud that means typing my password twice every time I wake my laptop: once for the screensaver and once for the keychain.
There should be a way to make the screensaver also unlock the keychain just the way the normal login also unlocks the keychain. Is there?
