Some progress and some questions Checking with strace the activity of freeradius in debug mode, I've seen that the daemon was triing to write into /tmp/user/0 which had root:root and 0711 privileges. Opening to 0777 makes the authentication successful and a radius_125 file (freerad:freerad owner) is created. Is it ok to have such a permission in this directory?
