mod_http_oauth2: Advertise the currently supported id_token signing algorithm This field is REQUIRED. The algorithm RS256 MUST be included, but isn't because we don't implement it, as that would require implementing a pile of additional cryptography and JWT stuff. Instead the id_token is signed using the client secret, which allows verification by the client, since it's a shared secret per OpenID Connect Core 1.0 § 10.1 under Symmetric Signatures. OpenID Connect Discovery 1.0 has a lot of REQUIRED and MUST clauses that are not supported here, but that's okay because this is served from the RFC 8414 OAuth 2.0 Authorization Server Metadata .well-known endpoint!

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

This checks the nickname of a joining user against a configurable list of
[Lua patterns](https://www.lua.org/manual/5.2/manual.html#6.4.1), and prevents
them from joining if it matches any of them.

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

There is a single configuration option, `muc_reserve_nick_patterns` and the
default is `{}` - i.e. allow everything.

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

Requires Prosody 0.11 or higher.
