/**
 * Extdb user sync script.
 *
 * This script is meant to be called from a system cronjob to
 * sync moodle user accounts with external database.
 * It is required when using internal passwords (== passwords not defined in external database).
 *
 * Sample cron entry:
 * # 5 minutes past 4am
 * 5 4 * * * sudo -u www-data /usr/bin/php /var/www/moodle/auth/db/cli/sync_users.php
 *
 * Notes:
 *   - it is required to use the web server account when executing PHP CLI scripts
 *   - you need to change the "www-data" to match the apache user account
 *   - use "su" if "sudo" not available
 *   - If you have a large number of users, you may want to raise the memory limits
 *     by passing -d memory_limit=256M
 *   - For debugging & better logging, you are encouraged to use in the command line:
 *     -d log_errors=1 -d error_reporting=E_ALL -d display_errors=0 -d html_errors=0
 *
 * Performance notes:
 * + The code is simpler, but not as optimized as its LDAP counterpart.
