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!

--- labels: - Stage-Alpha ... Introduction ============ This is an experimental authentication module that does an asynchronous HTTP call to verify username and password. This is a (possibly temporary) fork of mod_http_auth_async that adds support for authentication using a cookie and SASL EXTERNAL. Details ======= When a user attempts to authenticate to Prosody, this module takes the username and password and does a HTTP GET request with [Basic authentication][rfc7617] to the configured `http_auth_url`. Configuration ============= ``` lua VirtualHost "example.com" authentication = "http_auth_cookie" http_auth_url = "http://example.com/auth" http_cookie_auth_url = "https://example.com/testcookie.php?user=$user" ``` Cookie Authentication ===================== It is possible to link authentication to an existing web application. This has the benefit that the user logging into the web application in their browser will automatically log them into their XMPP account. There are some prerequisites for this to work: - The BOSH or Websocket requests must include the application's cookie in the headers sent to Prosody. This typically means the web chat code needs to be served from the same domain as the web application. - The web application must have a URL that returns 200 OK when called with a valid cookie, and returns a different status code if the cookie is invalid or not currently logged in. - The XMPP username for the user must be passed to Prosody by the client, or returned in the 200 response from the web application. Set `http_cookie_auth_url` to the web application URL that is used to check the cookie. You may use the variables `$host` for the XMPP host and `$user` for the XMPP username. If the `$user` variable is included in the URL, the client must provide the username via the "authzid" in the SASL EXTERNAL authentication mechanism. If the `$user` variable is *not* included in the URL, Prosody expects the web application's response to be the username instead, as UTF-8 text/plain. Compatibility ============= Requires Prosody trunk
