I have a group policy created for CEO to have the screen saver come on in 10 miuntes and password protected. We have a GPO for the rest of our users, but not set to 10 minutes. I placed his user account in a specific OU with this policy attached. On his desktop it shows the option for password protected for his screen saver and it does come in after 10 minutes. But, it doesn't prompt for the password to get back in.
