mod_auth_cyrus: Add empty 'profile' table to SASL handler objects This is for compatibility with Prosody's built-in util.sasl objects. A SASL profile table usually includes methods supported by the backend, which can be used by SASL mechanism handlers to perform operations (such as testing the password). It also optionally contains a 'cb' field with channel binding method handlers. The Cyrus backend doesn't support channel binding, and doesn't have the same concept of auth backend methods (it handles all that internally, and Prosody has no insight or control over it). Thus, we create an empty profile which informs Prosody that the SASL handler does not support any of the auth or channel binding methods. Some features will not work, but they didn't work anyway. This just makes it explicit. This fixes a traceback in mod_sasl2_fast, which expected SASL handlers to always contain a 'profile' field.

Introduction
------------

[OTR, "Off The Record"](https://otr.cypherpunks.ca/), encryption allows
clients to encrypt messages such that the server cannot read/modify
them.

This module allows the server admin to require that all messages are
OTR-encrypted.

Configuration
-------------

Just enable the module by adding it to your global `modules_enabled`, or
if you only want to load it on a single host you can load it only for
one host like this:

    VirtualHost "example.com"
        modules_enabled = { "require_otr" }
