Hi ider,

on Debian-based systems there may be problems with RADIUS, which lead to the fact that a login e.g. to a VPN is no longer possible.

If your system is configured accordingly, so-called “unattended updates” of FreeRADIUS can currently cause problems on Debian-based systems like Ubuntu LTS.
In such a case the configuration of FreeRADIUS could be changed so that authentication against privacyIDEA is no longer possible.

This automatic update can create new links in the directory /etc/freeradius/3.0/sites-enabled/.
However, only the link “privacyidea” is allowed to exist in this directory.

Troubleshooting

  1. remove all links from the directory /etc/freeradius/3.0/sites-enabled/
  2. set the correct link again
    ln -s /etc/freeradius/3.0/sites-available/privacyidea /etc/freeradius/3.0/sites-enabled/
  3. restart the FreeRADIUS server:
    systemctl restart freeradius.service

This happened only with ubuntu 18 configured systems with Freeradius
