Back we announced a new way to access the Admin console. Starting this week the existing Admin console URL (www.google.com/a/example.com) will redirect to a login URL at accounts.google.com. For SSO-enabled domains (without a network mask defined) only Super Admins will be permitted to log in with a Google password. Non-Super Admins will be redirected to the configured SSO login page.
