- the `ResourceCache` creates a `ServiceAccountLister` `informer`, but this is only used when RBAC is enabled
- if RBAC is not enabled, it is not used, and so does not need to be created
- also, if RBAC is not enabled, the Server's `ClusterRole` should not require `serviceaccount` permissions
- without this change, whenever SSO is enabled, the `ClusterRole` will require `serviceaccount` permissions, despite not actually needing it (i.e. not "least privilege")

I don't think the CI errors here are related as I didn't change the actual manifests and none of the failures are API failures. I assume flaky tests? |

ResourceCachewhen SSO RBAC is enabledVerification
There's no unit tests for this specific file / for the
NewArgoServerfunction. I might be able to write an E2E test for this, but am still learning that part of the codebase.rbac.enabled: true. Then running a subset of the Server E2E tests. Non-trivial change as far as I can tell so far, and may require a decent bit of modifications to theMakefileetc to run a new test + install a new manifest as well 😅Future Work
I feel like it might make sense to rename / move
resource_cache.go? It is only used by SSO RBAC and nothing else right now, as far as I can tell. The name feels misleading as a result as it seems more generic.
