Permit use of Data Sources preference extension

This policy setting allows you to permit or prohibit use of the Data Sources preference extension. When a preference extension is prohibited it does not appear in the Group Policy Management Editor window of the GPMC. If you enable this policy setting you permit use of the preference extension unless restricted by the “Permit use of Control Panel Settings (Computers)” or “Permit use of Control Panel Settings (Users)” policy settings. Enabling this policy setting overrides the “Restrict users to the explicitly permitted list of snap-ins” policy setting. If you disable this policy setting you prohibit use of the preference extension. If you do not configure this policy setting you permit use of the preference extension unless restricted by the “Restrict users to the explicitly permitted list of snap-ins” “Permit use of Control Panel Settings (Computers)” or “Permit use of Control Panel Settings (Users)” policy settings.
