It's great that you're exploring Azure Single Sign-On (SSO) and looking to expand the accessibility of your application to external clients and other organizations. Here's a step-by-step approach to achieve this:
- Azure Active Directory B2B (Business to Business) Collaboration:
- Azure AD B2B is the recommended way to share your applications with external users. It allows users from other organizations to access your application without creating new accounts in your Azure AD.
- To implement this, you would invite external users as guests in your Azure AD tenant. These users can then authenticate using their own organizational identities.
- The process involves sending invitations via email or creating a direct link that external users can use to access your application.
- Consent Framework for Multi-Tenant Applications:
- If your application needs to be accessible to users from multiple Azure AD tenants without specific invitations, consider registering your app as a multi-tenant Azure AD application.
- This setup allows users from other Azure AD tenants to consent to using your application. Once they consent, their tenant information is stored within your Azure AD, and they can authenticate using their own organizational credentials.
- Azure Marketplace:
- If you want to make your application broadly available to a wider range of Azure customers, consider publishing it on the Azure Marketplace.
- This is a more commercial approach and is suitable if your app is a product intended for general distribution.
- Documentation and Further Reading:
- For Azure AD B2B: Check out the Azure AD B2B documentation.
- For Multi-Tenant Apps: The documentation on how to build a multi-tenant application is a useful resource.
- For Azure Marketplace: The Azure Marketplace publishing guide provides comprehensive information.
- Best Practices:
- Always test with a small group of external users before rolling out broadly.
- Keep security in mind, especially regarding what data external users can access.
- Monitor and audit external access regularly to ensure compliance with your organization's policies.
By following these steps and utilizing Azure AD's capabilities, you can make your application accessible to external clients and other organizations in a controlled and secure manner.
