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: Compatibility layer for Prosody's future roles API
---

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

This module provides compatibility with Prosody's new role and permissions
system. It aims to run on Prosody 0.11 and 0.12, providing a limited version
of the new API backed by is_admin() (which is not going to be present in trunk
and future Prosody versions).

It is designed for use by modules which want to be compatible with Prosody
versions with and without the new permissions API.

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

There is no configuration.

Usage (for developers)
======================

If you are a module developer, and want your module to work with Prosody trunk
and future releases, you should avoid the `usermanager.is_admin()` function.

Instead, depend on this module:

```
module:depends("compat_roles")
```

Then use `module:may()` instead:

```
if module:may(":do-something") then
  -- Blah
end
```

For more information on the new role/permissions API, check Prosody's
developer documentation at https://prosody.im/doc/developers/permissions

Compatibility
=============

Requires Prosody 0.11 or 0.12.
