This module implements a mechanism via which clients can exchange a password |
|
11 |
for a secure token, improving security and streamlining future reconnections. |
|
12 |
||
13 |
At the time of writing, the XEP that describes the FAST protocol is still |
|
14 |
working its way through the XSF standards process. You can [view the FAST XEP |
|
15 |
proposal here](https://xmpp.org/extensions/inbox/xep-fast.html). |
|
16 |
||
17 |
This module depends on [mod_sasl2]. |

## Configuration |
|
20 |
||
21 |
| Name | Description | Default | |
|
22 |
|---------------------------|--------------------------------------------------------|-----------------------| |
|
23 |
| sasl2_fast_token_ttl | Default token expiry (seconds) | `86400*21` (21 days) | |
|
24 |
| sasl2_fast_token_min_ttl | Time before tokens are eligible for rotation (seconds) | `86400` (1 day) | |
|
25 |
||
26 |
The `sasl2_fast_token_ttl` option determines the length of time a client can |
|
27 |
remain disconnected before being "logged out" and needing to authenticate with |
|
28 |
a password. Clients must perform at least one FAST authentication within this |
|
29 |
period to remain active. |
|
30 |
||
31 |
The `sasl2_fast_token_min_ttl` option defines how long before a token will be |
|
32 |
rotated by the server. By default a token is rotated if it is older than 24 |
|
33 |
hours. This value should be less than `sasl2_fast_token_ttl` to prevent |
|
34 |
clients being logged out unexpectedly. |
