Non Super Admins cannot login after Domain Mapping Upgrade to 3.0.8

I just upgraded to Domain Mapping 3.0.8, and now non-SuperAdmins cannot log in to their sites. It’s a subdomain Network.

Checklist: I removed the old mu-plugin, uploaded the new plugin to the plugins folder, moved/overwrote the old sunrise.php file in the wp-content folder, then [re]activated the plugin.

As SuperAdmin, I can still log into all the site’s admin areas. Regular Admins, and any other lower role, cannot log into their sites.

Result: They are thrown back (redirected) into the wp-login page

http://site.domain.org/wp-login.php?redirect_to=http%3A%2F%2Fsite.domain.org%2F&reauth=1

This occurs even if all plugins are deactivated.
