mod_auth_http_cookie

Introduction

This is an experimental authentication module that does an asynchronous HTTP call to verify username and password.

This is a (possibly temporary) fork of mod_http_auth_async that adds support for authentication using a cookie and SASL EXTERNAL.

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 to the configured http_auth_url.

Configuration

It is possible to link authentication to an existing web application. This has the benefit that the user logging into the web application in their browser will automatically log them into their XMPP account.

There are some prerequisites for this to work:

Set http_cookie_auth_url to the web application URL that is used to check the cookie. You may use the variables $host for the XMPP host and $user for the XMPP username.

If the $user variable is included in the URL, the client must provide the username via the “authzid” in the SASL EXTERNAL authentication mechanism.

If the $user variable is not included in the URL, Prosody expects the web application’s response to be the username instead, as UTF-8 text/plain.

Compatibility

Requires Prosody trunk
