mod_http_oauth2: Add role selector to consent page
List includes all roles available to the user, if more than one.
Defaults to either the first role in the scope string or the users
primary role.
Earlier draft listed all roles, but having options that can't be
selected is bad UX and the entire list of all roles on the server could
be long, and perhaps even sensitive.
Allows e.g. picking a role with fewer permissions than what might
otherwise have been selected.
UX wise, doing this with more checkboxes or possibly radio buttons would
have been confusion and/or looked messier.
Fixes the previous situation where unselecting a role would default to
the primary role, which could be more permissions than requested.

--- 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
