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-Alpha' summary: | Warn admins about outgoing s2s connections that are refused due to invalid or untrusted certificates ... Introduction ============ Similar to mod\_watchregistrations, this module warns admins when an s2s connection fails due for encryption or trust reasons. The certificate shows the SHA1 hash, so it can easily be used together with mod\_s2s\_auth\_fingerprint. Configuration ============= modules_enabled = { -- other modules -- "watchuntrusted", } untrusted_fail_watchers = { "admin@example.lit" } untrusted_fail_notification = "Establishing a secure connection from $from_host to $to_host failed. Certificate hash: $sha1. $errors" Option Default Description ------------------------------- --------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------- untrusted\_fail\_watchers All admins The users to send the message to untrusted\_fail\_notification "Establishing a secure connection from \$from\_host to \$to\_host failed. Certificate hash: \$sha1. \$errors" The message to send, \$from\_host, \$to\_host, \$sha1 and \$errors are replaced untrusted\_message\_type `"chat"` Which kind of message to send. `"normal"` or `"headline"` are other sensible options untrusted\_ignore\_domains Empty The domains that this module should not warn about Compatibility ============= ------- ------- trunk Works ------- -------
