mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!) Problem: This was causing the key to become "<token>--cur" instead of the expected "<token>-cur". As the same key was used by the code to both set and get, it still worked. Rationale for change: Although it worked, it's unintended, inconsistent and messy. It increases the chances of future bugs due to the unexpected format. Side-effects of change: Existing '--cur' entries will not be checked after this change, and therefore existing FAST clients will fail to authenticate until they attempt password auth and obtain a new FAST token. Existing '--cur' entries in storage will not be cleaned up by this commit, but this is considered a minor issue, and okay for the relatively few FAST deployments.

# Introduction

This module allows you to make one or more MUCs as accessible to local users only.

# Details

Local users (anyone on the same server as the MUC) are granted automatic
membership when they first join the room. Users from other servers are
denied access (even if the room is otherwise configured to be open).

# Configuring

## Enabling

``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
    "muc_local_only";
}
```

## Settings

Specify a list of MUCs in your config like so:

```
muc_local_only = { "my-local-chat@conference.example.com" }
```

# Compatibility

Requires Prosody 0.11.0 or later.

# Future

It would be good to add a room configuration option.
