FreeRADIUS 2 server + FreeRADIUS client - something like POD (packet of disconnect)

[NiTr0]

I  use  FreeRADIUS v2.0.1 on server side and FreeRADIUS client library
v1.1.6  with  pptpd/pppd  on  client  side.  Is  there  something like
Mpd-drop-user  attribute  for  MPD5? Or I must hangup sessions only by
unusual  way with 3rd-party client-server apps (for ex., telnet, snmp,
etc)?
