How Django Microsoft SSO works?

Current Flow

1. First, the user is redirected to the Django login page. If settings MICROSOFT_SSO_ENABLED is True, the "Login with Microsoft" button will be added to a default form.

2. On click, Django-Microsoft-SSO will add, in a anonymous request session, the sso_next_url and Microsoft Auth info. This data will expire in 10 minutes. Then user will be redirected to Microsoft login page.

   Using Request Anonymous session

   If you make any actions which change or destroy this session, like restart django, clear cookies or change browsers, the login will fail, and you can see the message "State Mismatched. Time expired?" in the next time you log in again.

3. On callback, Django-Microsoft-SSO will check code and state received. If they are valid, Microsoft's UserInfo will be retrieved. If the user is already registered in Django, the user will be logged in. The Graph request has a timeout of 10 seconds, defined in MICROSOFT_SSO_GRAPH_TIMEOUT.

4. Otherwise, the user will be created and logged in, if his email domain, matches one of the MICROSOFT_SSO_ALLOWABLE_DOMAINS. You can disable the auto-creation setting MICROSOFT_SSO_AUTO_CREATE_USERS to False.

5. On creation only, this user can be set to thestaff or superuser status, if his email are in MICROSOFT_SSO_STAFF_LIST or MICROSOFT_SSO_SUPERUSER_LIST respectively. Please note if you add an email to one of these lists, the email domain must be added to MICROSOFT_SSO_ALLOWABLE_DOMAINStoo.

6. This authenticated session will expire in 1 hour, or the time defined, in seconds, in MICROSOFT_SSO_SESSION_COOKIE_AGE.

7. If login fails, you will be redirected to route defined in MICROSOFT_SSO_LOGIN_FAILED_URL (default: admin:index) which will use Django Messaging system to show the error message.

8. If login succeeds, the user will be redirected to the next_path saved in the anonymous session, or to the route defined in MICROSOFT_SSO_NEXT_URL (default: admin:index) as a fallback.
