Dear List Members, i have come across the problem that "dailycounter" that is (rlm_sqlcounter) do not reset. Users are rejected by the following message. "Your maximum daily usage time has been reached" i am trying to figure out the cause but unable to. Counter & Query in use: sqlcounter dailycounter { counter-name = "Daily-Session-Time" check-name = "Max-Daily-Session" reply-name = "Session-Timeout" sqlmod-inst = "sql" key = "User-Name" reset = "daily" cache-size = 5000 query = "SELECT SUM(acctsessiontime - GREATEST((%b - UNIX_TIMESTAMP(acctstarttime)), 0)) FROM radacct WHERE username = '%{%k}' AND UNIX_TIMESTAMP(acctstarttime) + acctsessiontime > '%b'" logs: rlm_sqlcounter: (Check item - counter) is less than zero rlm_sqlcounter: Rejected user prabhpal, check_item=3600, counter=2147056619 ++[dailycounter] returns reject Thanks
