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
