#92361 -- The pre-auth user feature does not work properly. patch by plumbley. since user_load() always includes the authenticated user permission, LT needs to specifically re-check it's possible removal of the role in the load op of hook_user(). this *should* counteract anything which might reset the user object in the page load -- any modules not using user_load to mess with the user object are doing it wrong.  :)
