/**
* 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.
