Problem: After Update to 4.3 Windows Clients Can Not Authenticate Through Radius

Problem

After updating to UCS 4.3 Windows clients cannot authenticate themselves

Environment

Tha radius server was installed manually with apt instead of using univention-install.

Solution

Completely remove the radius server package

apt remove freeradius
apt autoremove
apt purge freeradius

Install freeradius through univention-app

univention-app install radius

Configure your radius as needed.
