Special plug-ins

Several software plug-ins have been written specifically for the Software.

Moodle-to-Opplet (Moodle side)

A software plug-in is written specifically for CNM Moodle to transfer course completion data from CNM Moodle to the Software.

Moodle-to-Opplet (Opplet side)

Wikiware API

A software plug-in is written specifically for CNM MediaWiki to provide it with API that will allow the Software changing user rights in CNM MediaWiki such as add to a group, remove from the group, etc.

OpenStack (future extension)

The Software shall be integrated with the native OpenStack Keystone authorization system of OpenStack using the output on the LDAP protocol.

Keystone is an OpenStack's Identity API. It supports LDAP, OAuth, OpenID Connect, SAML and SQL. ... [Keystone] does not actually implement any user-management functions; rather, it provides plug-in interfaces so that organizations can leverage their current authentication services.
