Hi, I have checked a user in debugging of user via raddebug, if the user is not being found in radcheck table, the freeradius is still executing groupcheck and groupreply tables. It look like its causing extra load on mysql database. Is there a way to minimize them ? or is there a way that if the user is not found in radcheck, then freeradius should not execute other queries. Below is the debug result.
