 Hello, gents
Can you advise me with my issue with simultaneous logins, please?

I can't use radutmp because NAS port identifies only SSID (in case of Cisco WLC 5508). So it is always the same. And there are always only two records in the file.
I switched to SQL method:


session {

        #  See "Simultaneous Use Checking Queries" in sql.conf

acct_unique {
        key = "User-Name, Acct-Session-Id, NAS-IP-Address, Client-IP-Address"

But all my seesions became "closed" after less than 2 minutes with acctterminatecause = Stale-Session (radacct table)

So this query doesn't work
simul_count_query = "SELECT COUNT(*) \
                              FROM ${acct_table1} \
                              WHERE username = '%{SQL-User-Name}' \
                              AND acctstoptime IS NULL" Who decides that the session is stale? And how can I avoid it?
