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

--- labels: - 'Stage-Beta' summary: 'Enable ad-hoc command for XMPP clients to create invitations' ... Introduction ============ This module is part of the suite of modules that implement invite-based account registration for Prosody. The other modules are: - [mod_invites] - [mod_invites_page] - [mod_invites_register] - [mod_invites_register_web] - [mod_invites_api] - [mod_register_apps] For details and a full overview, start with the [mod_invites] documentation. Details ======= mod_invites_adhoc allows XMPP clients to create new invites on the server. Clients must support either XEP-0401 (Easy Onboarding) or XEP-0050 (Ad-hoc commands). There are three types of invitation that can be created: | Invite type | Description | |--|--| | Account-only invites | These can be used to register a new account | | Contact-only invites | These can be shared with a contact so they can easily add you to their contact list | | Account-and-contact invites | Like a contact-only invite, but also allows the contact to register on the current server if they don't already have an XMPP account | Only configured admins of the server are able to create account-only invites. By default normal users may only create contact-only invites, but account-and-contact invites can be enabled with the `allow_user_invites` option. Configuration ============= | Name | Description | Default | |-----------------------|-----------------------------------------------------------------------|-------------------------------------------| | allow_user_invites | Whether non-admin users can invite contacts to register on this server| `false` | | allow_contact_invites | Whether non-admin users can invite contacts to their roster | `true` | The `allow_user_invites` option should be set as desired. However it is strongly recommended to leave the other option (`allow_contact_invites`) at its default to provide the best user experience.
