Hi: I am testing 802.1x accounting under fr 3.0.8. steps below: 1. use my notebook to login AP. accounting begin. 2. poweroff/poweron the AP. AP send "Accounting on". and previous accounting log closed with "NAS-Reboot".that's good. 3. use my notebook to login AP. fr can not create a new accounting entry, it seems "Acct-Session-Id" will be reused and cause "acctuniqueid" duplicate. error message like below: (11) sql: rlm_sql_mysql: ERROR 1062 (Duplicate entry 'e8db0ea9accf3a44b835ff8a0e5b62c0' for key 'acctuniqueid'): 23000 (11) sql: SQL query returned: need alt query (11) sql: Trying next query... (11) sql: EXPAND UPDATE radacct SET acctstarttime = FROM_UNIXTIME(%{integer:Event-Timestamp})................... then fr will try to update an existing entry instead of log a new entry. is the behavior expected? how can I setup to prevent it? thanks a lot for help!
