Description (last modified by SergeyBiryukov)

wp_validate_application_password only checks for the existence of $_SERVER['PHP_AUTH_USER'] before calling wp_authenticate_application_password with both $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'].

In our environment (using Shibboleth-powered Single Sign-on), $_SERVER['PHP_AUTH_USER'] is already set, but $_SERVER['PHP_AUTH_PW'] is not defined.

I believe that this section:

// Check that we're trying to authenticate
if ( ! isset( $_SERVER['PHP_AUTH_USER'] ) ) {
	return $input_user;

should likely be extended to confirm the presence of both variables before calling wp_authenticate_application_password.

(Of course, I'm also now worried about what other problems we'll run into using PHP_AUTH_USER the way we are, but that's for another day!)
