New custom user with 'read' capability can't access /wp-admin

Hi there!
I’m developing a custom template with restricted pages.
I’ve set up a “verified_user” Role and a registration form for it.
Registration with this role happens normally as you can expect.
I need $result in order to append to debug log if returns false.

$result = add_role('verified_user', __('Verified User'), array(
		'read' => true,
		'access_restricted_page' => true,
		'delete_posts' => false,
	));

What’s the problem here?
As far as I can read in WP Docs the standard user (who can access his Admin Panel) has just the ‘read’ capability, right?

What’s missing?

Thanks!

K
