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

# Introduction

Similar to [mod_lastlog], this module records the last timestamp of
various events, but keeps the last timestamp per type of event, instead
of the last event.

# Usage

As with all modules, copy it to your plugins directory and then add it
to the modules\_enabled list:

``` {.lua}
modules_enabled = {
  -- other modules
  "lastlog2",
}
```

# Configuration

There are some options you can add to your config file:

  Name                   Type      Default   Description
  ---------------------- --------- --------- ---------------------------------
  lastlog\_ip\_address   boolean   false     Log the IP address of the user?

# Usage

You can check a user's last activity by running:

    prosodyctl mod_lastlog username@example.com

# Compatibility
