How can I force users to a particular subdomain to log in for MU (Multisite)?

1. I would recommend using Peters Login Redirect to redirect users after login I have used it before and works well.

   You could redirect users to the secure area by adding the below to your .htaccess file :

   Redirect 301 blog1.example.com/wp-admin/dashboard.php secure.example.com/wp-admin

2. I would get a wildcard SSL certificate. It allows an unlimited number of subdomains to be secured for your main domain.

   Then I would force SSL login in wp-config.php:

   define('FORCE_SSL_LOGIN', true);
   /* That's all, stop editing! Happy blogging. */
   require_once(ABSPATH . 'wp-settings.php');
