Is it possible to use modules_s/auth as a replacement for
modules_k/auth? Are they compatible from user point of view?
In ser the auth module is used more like a "library" (other modules use
it via auth_api). It has only 1 script function: consume_credentials().
In kamailio besides the api interface, it exports more script functions
(which seem to be simple wrappers over the already exported api
functions, so they would be easiy to add to auth(s) too).
