Hi, I'm experiencing problems with Simultaneous-Use and MySQL. Due I have two freeradius servers, I cannot use for accounting radutmp because if a radius gets a stop packet and the start one went to the other radius the driver fails, so all accounting is based on MySQL. The MySQL queries that the radius perform are the followings (using standard sql.conf file with simul_count_query uncommented, the file is attached) 1- authorize_check_query (gets the Simultaneous-Use := 1) 2- authorize_group_check_query 3- authorize_reply_query 4- authorize_group_reply_query 5- simul_count_query 6- postauth_query 7- accounting_start_query 8- accounting_update_query (updates the radacct table with the IP address from the pool) If I try to connect with the same user and the previous conection still established, this is the sequence of queries: 1- authorize_check_query 2- authorize_group_check_query 3- authorize_reply_query 4- authorize_group_reply_query 5- simul_count_query **returns 1** 6- simul_verify_query 7- accounting stop query **performs a stop in the previously established session** 8- postauth_query 9- accounting_start_query 10- accounting_update_query (updates the radacct table with the IP address from the pool) I think either simul_verify_query is wrong or there is something wrong with sql.conf. I've attached it. If I change Simultaneous-Use := 0 the user cannot connect as I should behave and the logs reports "Auth: Multiple logins (max 0)" Freeradius and freeradius-mysql are etch/testing packages Debian official packages (version 1.0.4-2) Any help would be appreciated, thanks in advance -- David
