External database enrolment happens at the moment when a user logs into Moodle. To check if it is working, you can log in as a student and then check that their list of courses is as you would expect. The process also unenrols users from courses if they are no longer in the database.
Synchronization Script
A script is provided that can synchronize all your user enrollments at once - both adding and removing users (and courses if specified). The script is called auth_db_sync_users.php and is found in the auth/db folder.
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). Example cron entry:
# 5 minutes past 4am 5 4 * * * /usr/bin/php -c /path/to/php.ini /path/to/moodle/auth/db/auth_db_sync_users.php
Notes:
- 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
- This only works for users that already exist in your Moodle site (see your authorization plugin)
Field Mapping Example:
Choose your fields from the Moodle database:
- enrol_localcoursefield: A course identifier from mdl_course, e.g. "idnumber"
- enrol_localuserfield: A user identifier from mdl_user, e.g. "idnumber"
- enrol_localrolefield: (optional) A role identifier from mdl_role, e.g. "shortname"
Create a view in your external database which matches the chosen field values from Moodle:
- enrol_remotecoursefield: A matching course identifier from your external database table, e.g. "course_number"
- enrol_remoteuserfield: A matching user identifier from your external database table, e.g. "userid"
- enrol_remoterolefield: (optional) A matching role identifier from your external database table, e.g. "role_name"
