Simultaneous-Use, Session section not executing

[Igor Smitran]

As far as i remember you need to enable checkrad.pl to have 
Simultaneous-Use working.

SQL query will retrieve row with Accounting-Stop=NULL and get session id 
from it.

checkrad.pl will check if that session id exists on NAS or this row was 
not updated (missing/missed acct stop packet from NAS).

If session exists on NAS then freeradius will respond with reject 
message "Simultaneous use not allowed".

Other members of group can correct me if i am wrong regarding this.

Uncommented sql in default and inner-tunnel at session section. Trying to simulate Simultaneous-Use from proxy. I know NAS sending accounting-request. I’m sending manual Access-Request and I sent Accounting-Response before that and I see at my radacct table I have accounting record with acctstoptime is null. So at the end of the day, I have access-request, I have accounting at the radacct table which it has acctstoptime is null. I expect to see when I send Access-Request RADIUS should return Access-Reject because user already have session with acctstoptime is null. Here is my radius debug and Im not seeing executing of session section in my debug.
