Hello, I have a PacketFence set up using FreeRADIUS v. 3.0.13. In PacketFence GUI I have set up a RADIUS secret key - a letter "x" for testing purposes, but when I try using radtest -x test test localhost:18120 0 x the radiusd -X -xx -d /usr/local/pf/raddb -n auth output is following : Mon Apr 3 17:01:03 2017 : Debug: (0) Received Access-Request Id 196 from 127.0.0.1:37337 to 127.0.0.1:18120 length 79 Mon Apr 3 17:01:03 2017 : Info: Dropping packet without response because of error: Received packet from 127.0.0.1 with invalid Message-Authenticator!

Thank you very much
