maestro buen dia estoy configurando freeradius en centos 5, he seguido el manual de configuracion que publico, agregando en la configucion ñla sig parte de codigo que creo hizo falta en:

......
module{
sql_log {
path = ${radacctdir}/sql-relay
acct_table = "radacct"
postauth_table = "radpostauth"

Start = "INSERT INTO ${acct_table} (AcctSessionId, UserName, \
NASIPAddress, FramedIPAddress, AcctStartTime, AcctStopTime, \
AcctSessionTime, AcctTerminateCause) VALUES \
('%{Acct-Session-Id}', '%{User-Name}', '%{NAS-IP-Address}', \
'%{Framed-IP-Address}', '%S', '0', '0', '';"
Stop = "INSERT INTO ${acct_table} (AcctSessionId, UserName, \
NASIPAddress, FramedIPAddress, AcctStartTime, AcctStopTime, \
AcctSessionTime, AcctTerminateCause) VALUES \
('%{Acct-Session-Id}', '%{User-Name}', '%{NAS-IP-Address}', \
'%{Framed-IP-Address}', '0', '%S', '%{Acct-Session-Time}', \
'%{Acct-Terminate-Cause}';"
Alive = "INSERT INTO ${acct_table} (AcctSessionId, UserName, \
NASIPAddress, FramedIPAddress, AcctStartTime, AcctStopTime, \
AcctSessionTime, AcctTerminateCause) VALUES \
('%{Acct-Session-Id}', '%{User-Name}', '%{NAS-IP-Address}', \
'%{Framed-IP-Address}', '0', '0', '%{Acct-Session-Time}','';"

Post-Auth = "INSERT INTO ${postauth_table} \
(user, pass, reply, date) VALUES \
('%{User-Name}', '%{User-Password:-Chap-Password}', \
'%{replyacket-Type}', '%S';"
}

#
# Create a unique accounting session Id. Many NASes re-use
# or repeat values for Acct-Session-Id, causing no end of
# confusion.
#
# This module will add a (probably) unique session id
# to an accounting packet based on the attributes listed
# below found in the packet. See doc/rlm_acct_unique for
# more information.
# Include another file that has the SQL-related configuration.
# This is another file only because it tends to be big.
#
# The following configuration file is for use with MySQL.
#
# For Postgresql, use: ${confdir}/postgresql.conf
# For MS-SQL, use: ${confdir}/mssql.conf
# For Oracle, use: ${confdir}/oraclesql.conf
#
$INCLUDE ${confdir}/sql.conf


}...
siguiendon con su manual

y al final en el resultado me sale lo siguiente
