By plugging the authentication backend into your django settings, the code will:

1. authenticate a user via Harvard Pin -- uses Pin 2 authentication for constructing the PGP-signed message
2. upon authentication, look up the person's info via HU LDAP
3. create a Django User object based on the HU LDAP information (username, last name, first name, email)

• Harvard specific

  • Register a Pin 2 Application

  • Request access to HU-LDAP

  • Pin2 public keys

• Other

  • django, assuming you're using this already.

  • python-ldap, used by hu_ldap_basic module for accessing HU-LDAP

  • gnupg, open source version of PGP.

  • python-gnupg, python interface to gnupg. Used by hu_pin_auth module for verifying PGP message.

• Install requirements/packages above.

  • public key install, see 'gpg --import public.key'

• Include "hu_ldap_basic" and "hu_pin_auth" modules on your PYTHON_PATH

  • hackish: sys.path.append('Django-HU-Pin_Auth/')

• In settings.py add 'hu_pin_auth.auth_hu_pin_backend_ldap.HarvardPinWithLdapAuthBackend' to the AUTHENTICATION_BACKENDS

  • example with standard backend + HU PIN backend:
    • AUTHENTICATION_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend', 'hu_pin_auth.auth_hu_pin_backend_ldap.HarvardPinWithLdapAuthBackend', )

• In settings.py, add GNUPG_HOME variable. Used by python-gnupg as described here

• Add "HU_PIN_LOGIN_APP_NAMES" tuple with your app name. This is the name given when you Register a Pin 2 Application

  • example: HU_PIN_LOGIN_APP_NAMES = ('FAS_MCB_AUTH_DEV',)

• Define these variables for LDAP authentication

  • LDAP_CUSTOMER_NAME
    • e.g. LDAP_CUSTOMER_NAME = 'fas_dept'
  • LDAP_CUSTOMER_PASSWORD
    • e.g. LDAP_CUSTOMER_PASSWORD = 'MR-potato-head-123'
  • LDAP_SERVER
    • e.g. LDAP_SERVER = 'ldaps://hu-ldap-test.harvard.edu'

• Include a "view_handle_pin_callback" url to match the url you specified in your Pin 2 Registration

• An example callback url and view may be seen in:

  • hu_pin_auth/urls.py: view_handle_pin_callback

    • ex/ url(r'^hu_auth/callback/$', 'view_handle_pin_callback', name='view_handle_pin_callback' ),

  • hu_pin_auth/views.py: def view_handle_pin_callback(request):

• For potential errors:

  • hu_pin_auth/templates/view_pin_login_failed.html

• Log out

  • hu_pin_auth/templates/registration/logout.html (includes link to the HU Pin logout page)

• Add a link to use PIN for admin (or other login.)

  • Example of link that was added to the django admin/login.html template. overriding-admin-templates
  • Include your app name where it reads 'FAS_MY_DEPT_AUTH_DEV': <a href="https://www.pin1.harvard.edu/pin/authenticate?__authen_application=FAS_MY_DEPT_AUTH_DEV&next={% url admin:index %}"><u>USE PIN LOGIN</u></a>
  • Example may be found in file: hu_pin_auth/templates/admin/login.html

• In the example above, a successful log in redirects back to the admin index page, to redirect to another page:

  • (a) Define 'next' in the url query string.
  • (b) Rewrite your view to go to the appropriate page (see example in hu_pin_auth/views.py)
