To check if the system will prompt users to enter their passwords to unlock the screen saver, run the following command:

/usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep askForPasswordDelay

If there is no result, or if "askForPasswordDelay" is not set to "5.0" or less, this is a finding.
