mod_http_oauth2: Implement stateless dynamic client registration Replaces previous explicit registration that required either the additional module mod_adhoc_oauth2_client or manually editing the database. That method was enough to have something to test with, but would not probably not scale easily. Dynamic client registration allows creating clients on the fly, which may be even easier in theory. In order to not allow basically unauthenticated writes to the database, we implement a stateless model here. per_host_key := HMAC(config -> oauth2_registration_key, hostname) client_id := JWT { client metadata } signed with per_host_key client_secret := HMAC(per_host_key, client_id) This should ensure everything we need to know is part of the client_id, allowing redirects etc to be validated, and the client_secret can be validated with only the client_id and the per_host_key. A nonce injected into the client_id JWT should ensure nobody can submit the same client metadata and retrieve the same client_secret

summary: Point alias accounts or domains to correct XMPP user
...

Introduction
============

This module allows you to set up aliases that alert people who try to
contact them or add them to their roster what your actual JID is.  This
is useful for changing JIDs, or just in the case where you own both
example.com and example.net, and want people who contact you@example.com
to be alerted to contact you at you@example.net instead.

This type of aliasing is well supported in the email world, but very hard
to handle with XMPP, this module sidesteps all the hard problems by just
sending the user a helpful message, requiring humans to decide what they
actually want to do.

This doesn't require any special support on other clients or servers,
just the ability to receive messages.

Configuration
=============

Add the module to the `modules_enabled` list.

    modules_enabled = {
        ...
        "alias";
    }

Then set up your list of aliases, aliases can be full or bare JIDs,
or hosts:

    aliases = {
        ["old@example.net"] = "new@example.net";
        ["you@example.com"] = "you@example.net";
        ["conference.example.com"] = "conference.example.net";
    }

You can also set up a custom response, by default it is:

    alias_response = "User $alias can be contacted at $target";

A script named mod_alias_postfixadmin.sh is included in this directory to
generate the aliases array directly from a postfixadmin MySQL database.
Instructions for use are included in the script.
