Django SAML2 Authentication Made EasyBy Lotterywest GoRillas TeamVersion: Use 1.1.4 for Django <=1.9, 2.x.x for Django >= 1.9, Latest supported django version is 4.0This project aims to provide a dead simple way to integrate SAML2
Authentication into your Django powered app. Try it now, and get rid of the
complicated configuration of SAML.Any SAML2 based SSO(Single-Sign-On) identity provider with dynamic metadata
configuration is supported by this Django plugin, for example Okta.Lotterywest GoRillas Team has forked this project fromhereto be able to extend the functionality of the repository that is no longer maintained.DependenciesThis plugin is compatible with Django 1.6/1.7/1.8/1.9/1.10. Thepysaml2Python
module is required.InstallYou can install this plugin viapip:$pipinstalldjango_saml2_author from source:$gitcloneLotterywestGoRillasTeam

SSO authentication service. Once the user is logged in and redirected back,
the plugin will check if the user is already in the system. If not, the user
will be created using Django's default UserModel, otherwise the user will be
redirected to their last visited page.How to use?Import the views module in your root urls.pyimportdjango_saml2_auth.viewsOverride the default login page in the root urls.py file, by adding these
linesBEFOREanyurlpatterns:# These are the SAML2 related URLs. You can change "^saml2_auth/" regex to# any path you want, like "^sso_auth/", "^sso_login/", etc. (required)url(r'^saml2_auth/',include('django_saml2_auth.urls')),# The following line will replace the default user login with SAML2 (optional)# If you want to specific the after-login-redirect-URL, use parameter "?next=/the/path/you/want"# with this view.url(r'^accounts/login/$',django_saml2_auth.views.signin),# The following line will replace the admin login with SAML2 (optional)# If you want to specific the after-login-redirect-URL, use parameter "?next=/the/path/you/want"# with this view.url(r'^admin/login/$',django_saml2_auth.views.signin),Add 'django_saml2_auth' to INSTALLED_APPSINSTALLED_APPS=['...','django_saml2_auth',]In settings.py, add the SAML2 related configuration.Please note, the only required setting isMETADATA_AUTO_CONF_URL.

which point to a method to be called. The referenced method should accept a
single argument which is a dictionary of attributes and values sent by the
identity provider, representing the user's identity.TRIGGER.CREATE_USERA method to be called upon new user creation. This
method will be called before the new user is logged in and after the user's
record is created. This method should accept ONE parameter of user dict.TRIGGER.BEFORE_LOGINA method to be called when an existing user logs in.
This method will be called before the user is logged in and after user
attributes are returned by the SAML2 identity provider. This method should accept ONE parameter of user dict.ASSERTION_URLA URL to validate incoming SAML responses against. By default,
django-saml2-auth-lw will validate the SAML response's Service Provider address
against the actual HTTP request's host and scheme. If this value is set, it
will validate against ASSERTION_URL instead - perfect for when django running
behind a reverse proxy.ENTITY_IDThe optional entity ID string to be passed in the 'Issuer' element of authn request, if required by the IDP.NAME_ID_FORMATSet to the string 'None', to exclude sending the 'Format' property of the 'NameIDPolicy' element in authn requests.
Default value if not specified is 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient'.USE_JWTSet this to the boolean True if you are using Django Rest Framework with JWT authenticationFRONTEND_URLIf USE_JWT is True, you should set the URL of where your frontend is located (will default to DEFAULT_NEXT_URL if you fail to do so). Once the client is authenticated through the SAML/SSO, your client is redirected to the FRONTEND_URL with the user id (uid) and JWT token (token) as query parameters.
Example: 'https://myfrontendclient.com/?uid=&token='
With these params your client can now authenticate will server resources.CustomizeThe default permissiondeniedpage and userwelcomepage can be
overridden.To override these pages put a template named 'django_saml2_auth/welcome.html'
or 'django_saml2_auth/denied.html' in your project's template folder.If a 'django_saml2_auth/welcome.html' template exists, that page will be shown
to the user upon login instead of the user being redirected to the previous
visited page. This welcome page can contain some first-visit notes and welcome
words. Thehttps://docs.djangoproject.com/en/1.9/ref/contrib/auth/#django.contrib.auth.models.Useris available within the template as theusertemplate variable.To enable a logout page, add the following lines to urls.py, before anyurlpatterns:.. code-block:: python# The following line will replace the default user logout with the signout page (optional)
url(r'^accounts/logout/$', django_saml2_auth.views.signout),

# The following line will replace the default admin user logout with the signout page (optional)
url(r'^admin/logout/$', django_saml2_auth.views.signout),To override the built in signout page put a template named
'django_saml2_auth/signout.html' in your project's template folder.If your SAML2 identity provider uses user attribute names other than the
defaults listed in thesettings.pyATTRIBUTES_MAP, update them insettings.py.For Okta UsersI created this plugin originally for Okta.The METADATA_AUTO_CONF_URL needed insettings.pycan be found in the Okta
web UI by navigating to the SAML2 app'sSign Ontab, in the Settings box.
