authorize_check_query and authorize_reply_query

Hello list, I'm using freeradius and have some doubts abot these steps. authorize_check_query = "store_check_query '%{Stripped-User-Name:-%{User-Name}},'''' authorize_reply_query = "store_check_query '%{Stripped-User-Name:-%{User-Name}},'''' At this moment I'm using both authorize (check and reply), executong in both steps an store procedure. The question is if is madatory use both auth or is possible use only one of them. i.e. only authorize_reply_query Thanks in advanced Guido
