Introduction

============

This is an experimental authentication module that does an asynchronous

HTTP call to verify username and password.

Details

=======

When a user attempts to authenticate to Prosody, this module takes the

username and password and does a HTTP GET request with [Basic

authentication][rfc7617] to the configured `http_auth_url`.

Configuration

=============

``` {.lua}

VirtualHost "example.com"

authentication = "http_async"

http_auth_url = "http://example.com/auth"

```
