   1 <?php
   2 /** auth_ldap_sync_users.php
   3  *
   4  * This script is meant to be called from a cronjob to sync moodle with the LDAP
   5  * backend in those setups where the LDAP backend acts as 'master'.
   6  *
   7  * Recommended cron entry:
   8  * # 5 minutes past 4am
   9  * 5 4 * * * /usr/bin/php -c /etc/php4/cli/php.ini /var/www/moodle/auth/ldap/auth_ldap_sync_users.php
  10  *
  11  * Notes:
  12  *   - If you have a large number of users, you may want to raise the memory limits
  13  *     by passing -d momory_limit=256M
  14  *   - For debugging & better logging, you are encouraged to use in the command line:
  15  *     -d log_errors=1 -d error_reporting=E_ALL -d display_errors=0 -d html_errors=0
  16  *
  17  * Performance notes:
  18  * We have optimized it as best as we could for Postgres and mySQL, with 27K students
  19  * we have seen this take 10 minutes.
  20  *
