You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no):

but if we are using the site with different single sign on option where site runs on both http:// and https:// the admin url also take the user into the single sign on authentication. How can we setup this url to by pass the single sign on setup. If this is not possible should we use the first user that login to the system become admin?
