Send Reject When User Logged In Already

Dear Users,
In my test environment I use a Mikrotik RB333 as NAS and FreeRADIUS 2.1.7.
How can I make this Simultaneous Use Checking Queries work? Although I
uncommented simul_count_query in dialup.conf I cannot see any difference and
users can still logon simultaneously (radwho displays same users twice as
connected). I do not want to FreeRADIUS to query NAS (with SNMP etc) in
order to know if user is connected, I want simply use this sql queries and
send a reject packet if user seems connected in RADIUS.
Should I write a stored procedure for authorize_check_query and send reject
if there is a record of this user in radacct table which has a null
acctstoptime?
Meanwhile NAS sends accounting packets successfully and RADIUS receives
them.
I am really stuck!
