mod_http_oauth2: Improve handling of redirect_uri matching and fallback Per OAuth 2.1, the client MUST provide a redirect_uri explicitly if it registered multiple. If it only registered a single URI, it may be omitted from the authorize request.

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

On a server with public registration it is usually desirable to prevent
registration of certain "reserved" accounts, such as "admin".

This plugin allows you to reserve individual usernames, or those
matching certain patterns. It also allows you to ensure that usernames
conform to a certain pattern.

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

Enable the module as any other:

    modules_enabled = {
      "block_registrations";
    }

You can then set some options to configure your desired policy:

  Option                           Default         Description
  -------------------------------- --------------- -------------------------------------------------------------------------------------------------------------------------------------------------
  block\_registrations\_users      `{ "admin" }`   A list of reserved usernames
  block\_registrations\_matching   `{ }`           A list of [Lua patterns](http://www.lua.org/manual/5.1/manual.html#5.4.1) matching reserved usernames (slower than block\_registrations\_users)
  block\_registrations\_require    `nil`           A pattern that registered user accounts MUST match to be allowed

Some examples:

    block_registrations_users = { "admin", "root", "xmpp" }
    block_registrations_matching = {
      "master$" -- matches anything ending with master: postmaster, hostmaster, webmaster, etc.
    }
    block_registrations_require = "^[a-zA-Z0-9_.-]+$" -- Allow only simple ASCII characters in usernames

Compatibility
