Mosquitto prevent duplicate login
<p>I want to prevent user from duplicate login.</p>

<p>Currently I use mosquitto with signing different PKI for each client, but even if I turn on off the <code>allow_annonymous</code> flag, the user can still connect the mosquitto server without username and password. (So user can duplicate login with one PKI)</p>

<p>Is there a way to ensure PKI can only login in one session? Is set the username/password file can prevent duplicate login? Or other way to disable duplicate login?</p>

<p>Thanks</p>
