i try to realize the following: posts with a custom post type should be password-protected by default
i found this which works great https://wordpress.stackexchange.com/questions/4952/forcing-all-posts-associated-with-a-custom-post-type-to-be-private
but i dont want the posts to be private so i chanced
$post->post_status = 'private';
$post->post_password = 'some_default_password';
to
$post->post_status = 'published';
$post->post_password = 'some_default_password';
but then there is no password protection
how can i get this done?
