Check Text ( C-70121r1_chk )
This validation procedure is performed on both the MDM Administration Console and the Samsung KNOX for Android device.

Check whether the appropriate setting is configured on the MDM Administration Console:
1. Ask the MDM administrator to display the "Allow Export Contact to Personal Mode" setting in the "Android KNOX Container >> Container Restrictions" rule.
2. Verify the setting is disabled.

On the Samsung KNOX for Android device:
1. Open the KNOX container.
2. Select "KNOX Settings".
3. Select "Share contacts and calendars".
4. Verify "Export to Personal Mode - Contacts (from KNOX)" is disabled and attempt to enable this setting.

If the "Export Contacts to Personal Mode" configuration in the MDM console is enabled, or if the user is able to successfully enable this setting, this is a finding.
