  18   * CAS user sync script.
  19   *
  20   * This script is meant to be called from a cronjob to sync moodle with the CAS
  21   * backend in those setups where the CAS backend acts as 'master'.
  22   *
  23   * Notes:
  24   *   - it is required to use the web server account when executing PHP CLI scripts
  25   *   - you need to change the "www-data" to match the apache user account
  26   *   - use "su" if "sudo" not available
  27   *   - If you have a large number of users, you may want to raise the memory limits
  28   *     by passing -d momory_limit=256M
  29   *   - For debugging & better logging, you are encouraged to use in the command line:
  30   *     -d log_errors=1 -d error_reporting=E_ALL -d display_errors=0 -d html_errors=0
  31   *
  32   * Performance notes:
  33   * We have optimized it as best as we could for PostgreSQL and MySQL, with 27K students
  34   * we have seen this take 10 minutes.
  35   *
