give it permission
just let the keychain be unlocked at all times. at startup make users logon, so you have some security, use a screensaver with password verification. then you don't have to enter the keychain password all the time.
keychain is perfect for this use, and i congratulate microsoft to make use of Apple's system technologies. (would you rather use their PassPort system?)
