Hi, I can`t start freerad with sudo under lxc Under debug mode server is started: sudo -u www-data /usr/sbin/freeradius -f -X Listening on auth address * port 5000 bound to server test_local_pppoe_services Listening on acct address * port 1813 bound to server test_local_pppoe_services Listening on proxy address * port 52599 Ready to process requests but in the service command server failed sudo -u www-data /usr/sbin/freeradius -f radiusd: ERROR - Cannot initialize supplementary group list for user freerad: Operation not permitted sudo -u www-data /usr/sbin/service freeradius start Failed to start freeradius.service: Access denied See system logs and 'systemctl status freeradius.service' for details. I went through all the logs, but I can't find anywhere if the problem is in radius, systemd, lxc or apparmor. Thanks for tips Regards SL
