too bad, this means code duplication in plugins... I had hoped that
evolution might emulate the calls with the start_book_view stuff if
get_contact_list isn't available. But seems I have to code it after all.

I got the authentication part working now. The trick was as you said
using get_supported_auth_methods to return "plain/password" as
authentication method. You also have to make sure the addressbook source
has the "user" and "auth" properties set to the username/authentication
method.
