title: Can I use an existing user as Django admin when enabling admin for the first time?
body: <p>I have built a Django site for a while, but I never enabled Django admin. </p>
  
  <p>User accounts are registered on both LDAP and Django, but the master record is based on LDAP. So I must use the account in LDAP as super user.</p>
  
  <p>When I enable Django Admin, I am prompted to create a super user. Can I use an existing account (registered on both LDAP and Django db) as super user?</p>
  
  <p>How?</p>
