Guidelines
• The MCU maintains a local record of:
—Audit Events – users that generate these events are marked as being either internal
or external.
—Successful user logins
—Failed user login attempts
• User passwords and user lockout policy for external users are managed via Active
Directory’s integration with the user’s host machine.
• Enabling or disabling Active Directory integration does not require a reset.
