we're running on Ubuntu 16.04.5 LTS. Sorry about the very verbose debug output. I took it with raddebug and
didn't know that's very verbose by default. Will take it to heart next time...
Unfortunately freeradius -Xv doesn't show the linked OpenSSL server on our system:
root at its-edurad-qm:~# freeradius -Xv
radiusd: FreeRADIUS Version 3.0.17, for host x86_64-pc-linux-gnu

It really seems to go into that direction - I found the following article: https://support.microsoft.com/en-us/help/3121002/windows-10-devices-can-t-connect-to-an-802-1x-environment

radiusd -Xv should show you the version of OpenSSL the server is linked against.
