I have installed ocserv 0.10.4 I can successfully authenticate against radius server. and accounting interim updates works well. but once user get disconnected ocserv dosn't send stop accounting to radius server and hence radius server treats it as a stale session. actually ocserv send stop session (stop accounting) after long delay after user gets disconnected and this makes a huge problem when simultaneous-us attribute is used in radius server cause user will not be able to login again until stop session packet is sent to radius server. so question is that how we can send stop accounting to radius server once user disconnected?
