It appears that MQTT protocol has no way of notifying client about publish failures due to access control. We should atleast send a puback packet mimicking success, otherwise the client will repeatedly attempt publishing till it gets a puback. This can quickly become a serious issue.\r\n\r\nIdeally, we should have a way of notifying the failure to the client, but my limited reading of MQTT spec did not help."},"comment":{"url":"https://api.github.com/repos/emqtt/emqttd/issues/comments/154283926","html_url":"https://github.com/emqtt/emqttd/issues/368#issuecomment-154283926","issue_url":"https://api.github.com/repos/emqtt/emqttd/issues/368","id":154283926,"user":{"login":"erylee","id":11869,"avatar_url":"https://avatars.githubusercontent.com/u/11869?v=3","gravatar_id":"","url":"https://api.github.com/users/erylee","html_url":"https://github.com/erylee","followers_url":"https://api.github.com/users/erylee/followers","following_url":"https://api.github.com/users/erylee/following{/other_user}","gists_url":"https://api.github.com/users/erylee/gists{/gist_id}","starred_url":"https://api.github.com/users/erylee/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/erylee/subscriptions","organizations_url":"https://api.github.com/users/erylee/orgs","repos_url":"https://api.github.com/users/erylee/repos","events_url":"https://api.github.com/users/erylee/events{/privacy}","received_events_url":"https://api.github.com/users/erylee/received_events","type":"User","site_admin":false},"created_at":"2015-11-06T04:39:58Z","updated_at":"2015-11-06T04:39:58Z","body":"@phanimahesh, PUBACK packet has no payload according to MQTT V3.1.1 protocol specification.
