Hello, I'm configuring a FreeRadius Ubuntu server to replace Windows NPS server. The Domain Controller is CA as well. The server is part of the domain and MSCHAP is configured. The "$ radtest -t mschap testuser testpassword 127.0.0.1 0 testing123" works as well. Now, I want to replace the snakeoil certificate by a generated server certificate, signed by Windows CA. I generated freeradius.cer (Signed by Win CA), freeradius.key and placed them in dir's below. ALso the Win root CA, I added in /usr/local/share/ca-certificates. [cid:6be2c43b-7b4f-4a79-8e69-5af486a693d9] Following, when I change eap like below; even with absolute path instead of ${certdir}; I get freeradius failure. [cid:a314427e-f5f0-4a90-8005-83d5d8032453] Systemctl restart freeradius: failure. radtest -t fails as well... Can someone point me the right direction? Thanks!!! Olivier
