There will be 3 modules: - auth - this module will contain all the code that is not tight to a specific method of authentication, so it will basically perform some sanity checks over the credentials in SIP messages to make sure that the credentials are well formed before they get to real authentication. This module will also contain *_challenge functions and consume_credentials. - auth_db - This module will contain code neccessary to perform authentication over a database. This module will contain www_authorize and proxy_authorize functions. - auth_radius - This module will contain code necessarry to perform authorization over radius, i.e. radius_www_authorize and radius_proxy_authorize. It will be possible to use both radius and database authentication simultaneously if needed. Group membership and URI checking (originaly in auth module) have been moved to separate modules. There will be also support for group membership checking over radius. Most of the radius related code was contributed by Juha Heinanen, he has our unfailing thanks for that. So as you can see, there is some progress :-). All the code was tested with freeradius server. In regards to radius_acc: Jiri is working on that but I do not know what is the current state, he is on vacation right now. Jan.
