Hi, the sync_users script is deprecated in Moodle 3.0 (from sync_task.php):
* @deprecated since Moodle 3.0 MDL-51824 - please do not use this CLI script any more, use scheduled task instead.
However the Moodle 3.0 External database authentication doc page at https://docs.moodle.org/30/en/External_database_authentication has not been updated to reflect this (see screenshot). I'm new to Moodle so probably not the best person to edit the documentation page.
