mod_invites_adhoc: Fail contact invite if user is not on current host
Only the username was being used, and the host of the requester ignored.
Luckily this only affects admins of the host. If they want to create an
account they can use the other command. If they want to create a contact
they should request from their account on this host.

| 4 summary: 'MQTT interface to Prosody''s pubsub' | |
| 5 ... | |

| 7 Introduction | |
| 8 ------------ | |
| 9 | |
| 10 [MQTT](http://mqtt.org/) is a lightweight binary pubsub protocol suited | |
| 11 to embedded devices. This module provides a way for MQTT clients to | |
| 12 connect to Prosody and publish or subscribe to local pubsub nodes. | |
| 13 | |
| 14 Details | |
| 15 ------- | |
| 16 | |
| 17 MQTT has the concept of 'topics' (similar to XMPP's pubsub 'nodes'). | |
| 18 mod\_pubsub\_mqtt maps pubsub nodes to MQTT topics of the form | |

| 21 ### Limitations | |
| 22 | |
| 23 The current implementation is quite basic, and in particular: | |
| 24 | |
| 25 - Authentication is not supported | |
| 26 - SSL/TLS is not supported | |
| 27 - Only QoS level 0 is supported | |
| 28 | |
| 29 ### Payloads | |
| 30 | |
| 31 XMPP payloads are always XML, but MQTT does not define a payload format. | |
| 32 Therefore mod\_pubsub\_mqtt will attempt to convert data of certain | |
| 33 recognised payload types. Currently supported: | |
| 34 | |
| 35 - JSON (see [XEP-0335](http://xmpp.org/extensions/xep-0335.html) for | |
| 36 the format) | |
| 37 - Plain UTF-8 text (wrapped inside | |
| 38 `<data xmlns="https://prosody.im/protocol/mqtt"/>`) | |
| 39 | |
| 40 All other XMPP payload types are sent to the client directly as XML. | |
| 41 Data published by MQTT clients is currently never translated, and always | |
| 42 treated as UTF-8 text. | |
| 43 | |
| 44 Configuration | |
| 45 ------------- | |
| 46 | |
| 47 There is no special configuration for this module. Simply load it on | |
| 48 your pubsub host like so: | |
| 49 | |
| 50 Component "pubsub.example.org" "pubsub" | |
| 51 modules_enabled = { "pubsub_mqtt" } | |
| 52 | |
| 53 You may also configure which port(s) mod\_pubsub\_mqtt listens on using | |
| 54 Prosody's standard config directives, such as `mqtt_ports`. Network | |
| 55 settings **must** be specified in the global section of the config file, | |
| 56 not under any particular pubsub component. The default port is 1883 | |
| 57 (MQTT's standard port number). | |
