This is a design page. It was used to design and discuss the initial implementation of the change. However, the state of this document does not necessarily correspond to the current state of the implementation since we do not keep this document up to date with further changes and bug fixes.

Blank Feature Template

https://pagure.io/SSSD/sssd/issue/XYZ

Short overview (up to a couple of sentences) of the change being designed. Might include pointers to reference materials (such as MSDN articles when designing an AD integration feature) or other information required to understand what the change is about.

Walk through one or more full examples of how the feature will be used. If this is an internal change only (refactoring, perhaps), include a sentence saying so.

Describe, without going too low into technical details, what changes need to happen in SSSD during implementation of this feature. This section should be understood by a person with understanding of how SSSD works internally but doesn’t have an in-depth understanding of the code. For example, it’s fine to say that we implement a new option foo with a default value bar, but don’t talk about how is foo processed internally and which structure stores the value of foo. In some cases (internal APIs, refactoring, …) this section might blend with the next one.

A more technical extension of the previous section. Might include low-level details, such as C structures, function synopsis etc. In case of very trivial features (e.g. a new option), this section can be merged with the previous one.

Does your feature involve changes to configuration, like new options or options changing values? Summarize them here. There’s no need to go into too many details, that’s what man pages are for.

This section should explain to a person with admin-level of SSSD understanding how this change affects run time behaviour of SSSD and how can an SSSD user test this change. If the feature is internal-only, please list what areas of SSSD are affected so that testers know where to focus.

Explain how to debug this feature if something goes wrong. This section might include examples of additional commands the user might run (such as keytab or certificate sanity checks) or explain what message to look for.
