External trigger for CoA

Hi, We'd like to trigger a CoA based on an external event. Is this possible? There was a mail thread back in 2010 I was just wondering if something has been changed so far: http://freeradius.1045715.n5.nabble.com/Freeradius-COA-trigger-td3204376.htm... I know the basic approach is to use radclient for that scenario. Unfortunately, radclient does not support TLS/RADSEC which is critical for us. In case this is not currently possible, can we just implement that? Say to allow getting external events for example from RabbitMQ? Thanks, Vadim
