I working on freeradius twith fortigate firewall . every things go fine and now I can make authentication and accounting. My problem is when making authentication for any user accounting-request from nas is send to Radius server and the user's info will insert again into radacct table, which will make big wrong in my program This is the Radius - x result when making authentication Sending Access-Accept of id 78 to 10.10.0.103 port 1030 Cisco-AVPair = "shell:priv-lvl=1" Idle-Timeout = 1000 Finished request 0.

This mean every user will has tow records in to radacct table how can I stop that .
