mod_http_oauth2: Limit revocation to clients own tokens in strict mode
RFC 7009 section 2.1 states:
> The authorization server first validates the client credentials (in
> case of a confidential client) and then verifies whether the token was
> issued to the client making the revocation request. If this
> validation fails, the request is refused and the client is informed of
> the error by the authorization server as described below.
The first part was already covered (in strict mode). This adds the later
part using the hash of client_id recorded in 0860497152af
It still seems weird to me that revoking a leaked token should not be
allowed whoever might have discovered it, as that seems the responsible
thing to do.

--- labels: - Stage-Beta summary: "Fast Authentication Streamlining Tokens" rockspec: dependencies: - mod_sasl2 --- This module implements a mechanism via which clients can exchange a password for a secure token, improving security and streamlining future reconnections. At the time of writing, the XEP that describes the FAST protocol is still working its way through the XSF standards process. You can [view the FAST XEP proposal here](https://xmpp.org/extensions/inbox/xep-fast.html). This module depends on [mod_sasl2]. ## Configuration | Name | Description | Default | |---------------------------|--------------------------------------------------------|-----------------------| | sasl2_fast_token_ttl | Default token expiry (seconds) | `86400*21` (21 days) | | sasl2_fast_token_min_ttl | Time before tokens are eligible for rotation (seconds) | `86400` (1 day) | The `sasl2_fast_token_ttl` option determines the length of time a client can remain disconnected before being "logged out" and needing to authenticate with a password. Clients must perform at least one FAST authentication within this period to remain active. The `sasl2_fast_token_min_ttl` option defines how long before a token will be rotated by the server. By default a token is rotated if it is older than 24 hours. This value should be less than `sasl2_fast_token_ttl` to prevent clients being logged out unexpectedly.
