mod_http_oauth2: Reject invalid attempt to register client without credentials The implicit flow works without a client_secret since the token is delivered directly, but all other currently supported grant types require client to authenticate using credentials, so it makes no sense to not issue credentials then.

local actions = {};

function actions.auth(data)
	local user, host, pass = data:match("^([^:]+):([^:]+):(.+)$");
	if user == "someone" then
		return "1";
	end
end

for line in io.lines() do
	local action, data = line:match("^([^:]+)(.*)$");
	print(actions[action] and actions[action](data) or "0");
end
