in 1.0 there is both $r->auth_type and $c->auth_type, and they have different meanings.
$r->auth_type represents the AuthType from the config (via r->per_dir_config). when you get $r->auth_type, you're asking what kind of authentication is configured for the request.
$c->auth_type is populated by authen handlers, after the user has been authenticated, with whatever authentication method was used. I'm not sure about the history of this, but I suppose in theory it is possible for a client to request Digest auth, but the server fall back to Basic.
at any rate, I don't know how the current 2.0 or 2.1 aaa stuff handles this difference, if at all, but we (well, I :) need to be clear on how that works before agreeing that $r->connection->auth_type in Apache::Compat is the same as $r->auth_type.
