Open Source at Opinsys

Opinsys relies heavily on top of open source software such as Ubuntu, LTSP and various web technologies. Without Open Source software there would be no Opinsys. That’s why we try to contribute back as much as possible. Here we list our most visible Open Source projects. For full list of projects take a look at our Github page.

Puavo Users

Puavo Users is a major part of Puavo software family. It manages users and groups in an OpenLDAP directory which is then used to provide logins for desktop computers and various web services.

The goals are ease of use, integration with existing applications used in schools and security.
