Some quick notes about the demo:

  • The demo data will reset every hour
  • The demo application is running in a low service tier and may take a few seconds to spin up.
  • In a real deployment, subdomains can be used to resolve tenants. In the demo, tenants are switched at login with the tenant selection.
  • To see data isolation in action, try logging in as different tenant users.
  • Only the root tenant can access the tenant management area.
  • Only admin level users can access the user administration area.
  • Every tenant has a default admin:
  • The password for all users: Password123!
