If you forget your Django admin user/pass, here is an easy way to access:

(You need root access to your server)

ubuntu@ip-172-16-1-1:~/sites/testsite$ python manage.py createsuperuser
  
Username: admin
  
Email address: email@domain.com
  
Password:\****
  
Password (again):\****
  
Superuser created successfully.

Then you can login and check your existing details.
