WordPress MU

Hi everyone,

I am trying to modify a great plug by Will Norris for Shibboleth logins. The plugin is ignoring the "Allow new registrations" setting on site options page. I've looked at http://codex.wordpress.org/WPMU_Functions for something to check the setting. We have two blogs an open one for students and a restricted one for departments. We want to be able to disable registrations on the department blog but keep the authentication mechanism. Is there away to verify registration is enabled?

get_site_option('registration'); // none, all, user, blog

Usage in wp-admin/wpmu-options.php
