MPD : mpd-drop-user

Dear all, Is anyone try this attribute /*mpd-drop-user*/ in freeradius with Mysql? MPD support this attribute to check the status of account during it update the accounting and if the value for this attribute become non-zero, it will disconnect the session for the user. We use MPD to setup a PPPoE server with freeradius to provide authentication to users and we have come across to drop the session if the user's account suspended but we have no luck to make it work. Currently we try to put this attribute in radreply table and it doesn't work for us. Looking for your kind information in this matter. Thanks in advance. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
