mod_invites_register_api: Use set_password() for password resets Previously the code relied on the (weird) behaviour of create_user(), which would update the password for a user account if it already existed. This has several issues, and we plan to deprecate this behaviour of create_user(). The larger issue is that this route does not trigger the user-password-changed event, which can be a security problem. For example, it did not disconnect existing user sessions (this occurs in mod_c2s in response to the event). Switching to set_password() is the right thing to do

local jid = require "util.jid";
local st = require "util.stanza";

local nick_patterns = module:get_option_array("muc_reserve_nick_patterns", {});

module:hook("muc-occupant-pre-join", function (event)
	local nick = jid.resource(event.occupant.nick);
	for k, nick_pattern in pairs(nick_patterns) do
		if nick:match(nick_pattern) then
			local reply = st.error_reply(event.stanza, "modify", "conflict", "Unacceptable nickname, please try another");
			module:send(reply);
			return true;
		end
	end
end);
