redirect_to attribute not working in Shibboleth 2.0.2

Thank you for reporting this issue. I’m not experiencing this issue and am running 2.0.2 on production sites. I’m confused where that code that you are supplying is coming from? Please provide additional information, and also can you please cross post your issue to GitHub?

The code is at the top of the page.php template. Selected pages on the site require a Shibboleth login, and this code checks to see if the current page requires the login. The login piece works, but the user is not returned to the page that initiated the login. The user is instead directed to the wp-login page. This works fine in v1.8.1, which is why I suspected there was a change in v2. The complete piece of this code is:

$prot1 = get_field('level_1_protected_pages', 'option');

if($prot1) {
	foreach($prot1 as $page_id) {
		if($page_id['page'] === $post->ID) {
			if (!shibboleth_session_active()) {
				header('Location: ' . home_url() . '/wp-login.php?redirect_to=' . get_the_permalink($post->ID) . '&reauth=1&action=shibboleth');
			}
			else {
				$emp_id = $_SERVER['HTTP_****'];
				$emp_cat = $_SERVER['HTTP_AFFILIATION'];
					
				//test if student but not employee
				if (strpos($emp_cat, 'student') !== false && strpos($emp_cat, 'employee') === false) {
					header('Location: ' . home_url() . '/access-denied');
				}
			}
		}
	}
}
