CNaas - NAC (Network Access Control)

In order to provide end users with an authentication mechanism CNaaS NAC was invented. It relies on freeradius ( for user authentication using 802.1X with MAB as fallback for clients not being able to use 802.1X.

Source code is available on GitHub:

Freeradius can either be integrated towards the existing user database (LDAP, Active Directory etc) or use Postgres to store credentials. CNaaS NAC provides both an API and a web interface to handle users if Postgres is chosen for storing credentials.
