UCS@School contains students and teachers in one group with the same attributes in the LDAP. Moodle, however, expects them to be in different groups or LDAP attributes. This Cool Solution contains a listener that places the users in different attributes depending on their UCS@School role.
Prerequisites
This article is based on a successful installation of Moodle and one authentication method accomplished by following our Cool Solution - Install Moodle and assumes you already have authentication configured either via SAML authentication or LDAP authentication.
Tested with moodle 4.1.2
LDAP Search User
If you are using SAML, you will need to set up a simple authentication account for the LDAP lookups. Follow Cool Solution - LDAP search user / simple authentication account to do so now.
Installing the Cool Solution Listener
Please enable the Cool-Solutions Repository for UCS 5.0 Afterward, you can install the Listener with:
uninvention-install univention-moodle-group
The listener will now place students in univentionFreeAttribute20 and teachers into univentionFreeAttribute19.
Enabling the LDAP enrollment plugin
After successfully setting up an authentication method, you can now configure LDAP enrolments to enroll your UCS@school users into moodle courses automatically.
First, enable the LDAP enrolment plugin under Site Administration → Plugins → Enrolments. This plugin is already installed and only needs to be activated by pressing the icon in the Enable section.
To log in with the local moodle administrator account after you have set up SAML authentication, use https://<YOUR_MOODLE_SERVER_FQDN>/moodle/login/index.php?saml=off
To open the login page and sign in.
LDAP enrollment settings
After the plugin is enabled, open the plugin-settings.
