Seamless automatic multi-site authorization for all internal [team Team] resources.

Nginx example setup: nginx/nginx.conf. Outline:

• /.sso/authorize everywhere should be proxied to the app with internal; proxy_pass_request_body off;
• We need a domain where user profile will be stored (main_domain). It should be proxied to the app.
• On all domains, auth_request /.sso/authorize should be added, error_page 401 should be set to redirect to /.sso/login?next=$request_uri and /.sso should be proxied to the app

Settings example (.env file):

DATABASE_URL=postgresql+asyncpg://nora:nora@localhost:16432/nora
DEBUG=True
MAIN_DOMAIN=localhost:8001
ALLOWED_DOMAINS=["demo.localhost:8001", "localhost:8001"]
