Dear all, I've configured my radius to load value of timeout based on NAS-Port-Type.. Using LDAP for user's entry.. In LDAP.. user's entry will have additional 2 attributes TimeoutPSTN: 4000 TimeoutISDN: 1000 then in users file.. using exec to run small script to get correct value of sessiontimeout based on NAS-Port-Type DEFAULT NAS-Port-Type == "Sync", Autz-Type := DIALUP, Auth-Type := DIALUP Session-Timeout = `%{exec:/usr/local/etc/raddb/timeout.pl %U ISDN}` DEFAULT NAS-Port-Type == "Async", Autz-Type := DIALUP, Auth-Type := DIALUP Session-Timeout = `%{exec:/usr/local/etc/raddb/timeout.pl %U PSTN}` And its works... But my question is there any better way to do this?? Maybe directly get value from LDAP.... thanks.. --haizam
