Linelog not creating file in /var/log

We are using v3.0.13 - We have enabled the linelog but its not creating any log file under /var/log. - We kept no change in linelog module. Is there anything we need to enable to make it work? ******* # Loading module "linelog" from file /etc/raddb/mods-enabled/linelog linelog { filename = "/var/log/radius/linelog" escape_filenames = no syslog_facility = "auth" syslog_severity = "info" permissions = 384 group = "radiusd" format = "This is a log message for %{User-Name}" reference = "messages.%{%{reply:Packet-Type}:-default}" } ******* Regards, Raghu.
