mod_http_oauth2: Fix treatment of 'redirect_uri' parameter in code flow It's optional and the one stored in the client registration should really be used instead. RFC 6749 says an URI provided as parameter MUST be validated against the stored one but does not say how. Given that the client needs their secret to proceed, it seems fine to leave this for later.

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.
