I did google alot and still did not manage to find an answer, so I ask here, hope someone can help on this,

my freeradius is running as a proxy, and I want to add a exec command when authentication is successful. 

so I add exec in the post-proxy { , 

but how to filter by the authentication result ?  I want to trigger it only when Access-Accept,   

if dont have this filter, then how to pass the Access-Accept or Access-Reject into my script ?

thanks very much
