freeradius 2.1.0 default mysql schema don't have nasidentifier table. And the mysql query in dialup.conf also don't have nasidentifier value. It is purposely left out the nasidentifier? My work around is adding nasidentifier and it's value as below. accounting_start_query = " \ INSERT INTO ${acct_table1} \ (acctsessionid, acctuniqueid, username, \ realm, nasipaddress, nasidentifier, nasportid, \ nasporttype, acctstarttime, acctstoptime, \ acctsessiontime, acctauthentic, connectinfo_start, \ connectinfo_stop, acctinputoctets, acctoutputoctets, \ calledstationid, callingstationid, acctterminatecause, \ servicetype, framedprotocol, framedipaddress, \ acctstartdelay, acctstopdelay, xascendsessionsvrkey) \ VALUES \ ('%{Acct-Session-Id}', '%{Acct-Unique-Session-Id}', \ '%{SQL-User-Name}', \ '%{Realm}', '%{NAS-IP-Address}', '%{NAS-Identifier}', '%{NAS-Port}', \ '%{NAS-Port-Type}', '%S', NULL, \ '0', '%{Acct-Authentic}', '%{Connect-Info}', \ '', '0', '0', \ '%{Called-Station-Id}', '%{Calling-Station-Id}', '', \ '%{Service-Type}', '%{Framed-Protocol}', '%{Framed-IP-Address}', \ '%{%{Acct-Delay-Time}:-0}', '0', '%{X-Ascend-Session-Svr-Key}')" accounting_stop_query_alt = " \ INSERT INTO ${acct_table2} \ (acctsessionid, acctuniqueid, username, \ realm, nasipaddress, nasidentifier, nasportid, \ nasporttype, acctstarttime, acctstoptime, \ acctsessiontime, acctauthentic, connectinfo_start, \ connectinfo_stop, acctinputoctets, acctoutputoctets, \ calledstationid, callingstationid, acctterminatecause, \ servicetype, framedprotocol, framedipaddress, \ acctstartdelay, acctstopdelay) \ VALUES \ ('%{Acct-Session-Id}', '%{Acct-Unique-Session-Id}', \ '%{SQL-User-Name}', \ '%{Realm}', '%{NAS-IP-Address}', '%{NAS-Identifier}', '%{NAS-Port}', \ '%{NAS-Port-Type}', \ DATE_SUB('%S', \ INTERVAL (%{%{Acct-Session-Time}:-0} + \ %{%{Acct-Delay-Time}:-0}) SECOND), \ '%S', '%{Acct-Session-Time}', '%{Acct-Authentic}', '', \ '%{Connect-Info}', \ '%{%{Acct-Input-Gigawords}:-0}' << 32 | \ '%{%{Acct-Input-Octets}:-0}', \ '%{%{Acct-Output-Gigawords}:-0}' << 32 | \ '%{%{Acct-Output-Octets}:-0}', \ '%{Called-Station-Id}', '%{Calling-Station-Id}', \ '%{Acct-Terminate-Cause}', \ '%{Service-Type}', '%{Framed-Protocol}', '%{Framed-IP-Address}', \ '0', '%{%{Acct-Delay-Time}:-0}')"
