Reverting Flows: A Guide For WSO2 Sub-Organizations

Hey guys! Ever faced a situation where you've overridden a flow in a sub-organization and then thought, "Oops, I need to go back to the original"? Well, you're not alone! Currently, there's a limitation in WSO2 Identity Server that doesn't allow sub-organizations to revert back to the inherited flow once an override has been applied. Let's dive into this, understand the problem, and explore potential solutions.

Current Limitation: The Reversion Conundrum

So, here’s the deal. In the current setup, flows are inherited from the parent organization in a hierarchical structure. This is super handy because you can set up a base flow and then let sub-organizations inherit it. However, these sub-organizations have the power to override these inherited flows to suit their specific needs. That’s cool and flexible, but the problem arises when a sub-organization decides it wants to ditch the override and go back to the original, inherited flow. As it stands, there’s no direct way to do this.

Think of it like this: Imagine your parent company sets up a standard login flow. One of your sub-organizations decides to tweak it a bit. But later, they realize the original flow was better for them. Currently, they're stuck with their modified version unless they manually reconfigure everything to match the parent's flow. This can be a real headache, especially if the changes were complex or if multiple sub-organizations are in the same boat.

This limitation can lead to several issues. For instance, maintaining consistency across different sub-organizations becomes challenging. If each sub-organization makes changes and can’t easily revert, you end up with a fragmented system where troubleshooting and updates become a nightmare. Imagine trying to debug an authentication issue when each sub-organization has a slightly different flow – yikes!

Moreover, this lack of reversion capability can hinder agility. Organizations need to be able to adapt quickly to changing requirements or compliance standards. If reverting a flow requires a manual overhaul, it slows down the whole process and increases the risk of errors. Nobody wants to spend hours manually tweaking configurations when a simple revert button would do the trick!

To really drive this home, let’s consider a specific scenario. Suppose a sub-organization overrides a flow to add an extra layer of authentication for a specific application. Later on, they realize this extra layer is causing friction for users and decide it’s not worth the hassle. Without a revert option, they're forced to either live with the suboptimal flow or spend valuable time and resources manually undoing the changes. This is precisely the kind of situation we want to avoid.

Suggested Improvement: A Revert Capability to the Rescue

Now, let's talk solutions! The suggested improvement here is straightforward but incredibly powerful: implement a revert capability for flows, similar to what’s already available for UI branding, email content, SMS content, and login/registration configurations. This would be a game-changer for managing flows in sub-organizations.

Think about how easy it is to revert UI branding, for example. If a sub-organization experiments with a new look and feel but decides it’s not working, they can simply click a button to go back to the default branding. The same logic should apply to flows. A “Revert to Inherited Flow” button would allow administrators to quickly and easily restore the original flow, saving time and reducing the potential for errors.

This feature would not only simplify management but also promote experimentation and innovation. Sub-organizations would be more willing to try out new flow configurations if they knew they could easily revert to the original if needed. It’s like having an “undo” button for your flows – super reassuring!

To make this revert capability even more robust, it could include versioning. Imagine being able to not just revert to the immediate parent flow, but also to specific versions of that flow. This would add an extra layer of control and flexibility, allowing organizations to roll back to a known good state if something goes wrong.

Furthermore, a clear audit trail would be essential. Knowing who reverted a flow and when can be invaluable for troubleshooting and compliance purposes. A detailed log of flow changes and reversions would provide transparency and accountability, ensuring that any issues can be quickly identified and resolved.

The implementation of this revert capability would align the management of flows with other configurable elements in WSO2 Identity Server, creating a more consistent and user-friendly experience. It would also empower sub-organizations to adapt and evolve their flows without the fear of getting stuck with unwanted changes.

Areas Affected: API Access Management & Authorization

This issue primarily affects the realm of API Access Management and Authorization. Flows are crucial in defining how users are authenticated and authorized to access APIs. When sub-organizations can't easily revert overridden flows, it can lead to inconsistencies in API access policies, potentially creating security vulnerabilities or disrupting services.

For example, a sub-organization might override a flow to implement a stricter authentication mechanism for a specific API. If they later need to relax these restrictions due to usability issues or changing business requirements, the lack of a revert option makes it difficult to do so. This can result in a situation where users are unnecessarily burdened with cumbersome authentication processes, leading to frustration and decreased productivity.

Moreover, inconsistent API access policies across sub-organizations can complicate compliance efforts. If each sub-organization has its own unique set of flows and policies, ensuring adherence to industry regulations and internal standards becomes a complex and time-consuming task. A centralized revert capability would help maintain consistency and simplify compliance management.

Therefore, addressing this limitation is not just about convenience; it's about ensuring the security and reliability of API access management. By providing a way to easily revert overridden flows, WSO2 Identity Server can empower organizations to maintain consistent and secure API access policies across all their sub-organizations.

Developer Checklist: Ensuring a Smooth Transition

For the developers tackling this improvement, there's a checklist to ensure a smooth and comprehensive implementation. This checklist covers key aspects such as behavioral changes, migration impact, and new configurations. Let's break it down:

• [Behavioural Change] Does this change introduce a behavioral change to the product?

  • Absolutely! Adding a revert capability is a significant behavioral change. Users will now have a new option for managing flows, which wasn't available before. This needs careful consideration and clear communication.
  • [ ] Approved by team lead: This is a must. The team lead needs to sign off on the proposed changes to ensure they align with the product roadmap and overall strategy.
  • [ ] Label impact/behavioral-change added: Tagging the issue with this label helps in tracking and prioritizing behavioral changes, ensuring they receive the necessary attention during testing and documentation.

• [Migration Impact] Does this change have a migration impact?

  • This is a crucial question. If the revert capability involves changes to the underlying data structure or configuration files, it could impact existing deployments. We need to assess whether users will need to perform any migration steps when upgrading to a version with this feature.
  • [ ] Migration label added (e.g., 7.2.0-migration): If there's a migration impact, adding a version-specific label helps in categorizing and addressing migration-related tasks.
  • [ ] Migration issues created and linked: Detailed migration issues should be created, outlining the steps users need to take to migrate their configurations. These issues should be linked to the main feature issue for easy tracking.

• [New Configuration] Does this change introduce a new configuration?

  • It's possible that this feature might require new configuration options, such as settings for versioning or audit logging. If so, these need to be properly documented.
  • [ ] Label config added: Tagging the issue with this label ensures that configuration-related aspects are given due consideration.
  • [ ] Configuration is properly documented: Clear and comprehensive documentation is essential for any new configuration options. This documentation should explain the purpose of each option, how to configure it, and any potential impact on the system.

By following this checklist, the development team can ensure that the revert capability is implemented in a way that is both robust and user-friendly. It's all about making life easier for the users and ensuring a smooth transition to the new feature.

Conclusion: Empowering Sub-Organizations with Reversion
