Analysis / Root cause:

When Direct Authentication (structured authentication / external OIDC) is enabled on OpenShift, the built-in group.openshift.io model no longer exists. The impersonation modal's group selector attempts to enumerate Group resources via useK8sWatchResource, which fails with "Model does not exist", making group impersonation unusable in the UI. Group impersonation itself remains valid — Kubernetes RBAC continues to honor Impersonate-Group headers regardless of the Group model's existence.

Solution description:

Replaced the hard-coded enumerated group selector with a creatable typeahead that supports two modes:

  1. When Group model exists (standard OAuth): Groups are fetched from the API and displayed as typeahead suggestions in the dropdown. Users can still select from the list, use "Select all", and filter by typing. Additionally, users can create free-form group entries not in the list.

  2. When Group model is absent (Direct Authentication / external OIDC): No error is shown. The dropdown gracefully degrades to free-form entry mode with a helper text: "Type group names manually. Press Enter to add each group." Users type a group name and press Enter (or click the "Create" option) to add it.

Key changes:

  • Added onKeyDown handler for Enter key to create free-form group entries
  • Added "Create" dropdown option for typed text not matching existing groups
  • Removed the blocking error Alert for group load failures
  • Added FormHelperText guidance when the Group model is unavailable
  • Preserved all existing functionality: multi-group selection, chip display, expandable chips (5+ groups), "Select all" (when groups are available)

Screenshots / screen recording:

Test setup:

  • For standard mode: Use a cluster with built-in OAuth (group.openshift.io available)
  • For Direct Authentication mode: Configure structured authentication / external OIDC so the Group model is absent

Test cases:

  • Standard mode: Open impersonation modal → groups dropdown shows API groups as before
  • Standard mode: Type a group name not in the list → "Create" option appears → click or Enter adds it
  • Direct Auth mode: Open impersonation modal → no error alert shown
  • Direct Auth mode: Helper text "Type group names manually..." is visible
  • Direct Auth mode: Type group names + Enter → chips appear → submit works with free-form groups
  • Multiple free-form groups can be added and removed
  • Existing chip expansion behavior (5+ groups) still works
  • Form resets when modal is closed and reopened

Browser conformance:

  • Chrome
  • Firefox
  • Safari (or Epiphany on Linux)

Additional info:

  • Jira: OCPBUGS-112263
  • Related: RFE-9146 (service account impersonation in the Console) — same modal
  • Non-goal per ticket: Do NOT enumerate groups from RoleBinding subjects

Summary by CodeRabbit

  • New Features

    • Added support for manually entering group names when available groups cannot be loaded.
    • Users can create groups by typing a name and pressing Enter or selecting “Create.”
    • Added support for multiple custom groups while preventing duplicates.
    • Added clearer guidance for empty searches, unavailable groups, and already-added groups.
  • Bug Fixes

    • Removed the failure alert when group loading is unavailable and replaced it with actionable manual-entry guidance.

Walkthrough

ImpersonateUserModal now supports free-form group entry. Users can create groups with the Create option or Enter, including when group loading fails. Tests cover duplicate prevention, helper text, submission, and username-only impersonation.

Changes

Manual group entry

Layer / File(s) Summary
Modal state and group creation
frontend/public/components/modals/impersonate-user-modal.tsx
The modal conditionally mounts its content, detects group availability, creates trimmed non-duplicate groups, and handles Enter-key creation.
Group options and manual-entry guidance
frontend/public/components/modals/impersonate-user-modal.tsx, frontend/public/locales/en/public.json
The modal renders create, duplicate, API-group, and manual-entry options. Localization adds labels and guidance for these states.
Behavior validation
frontend/public/components/modals/__tests__/impersonate-user-modal.spec.tsx, frontend/public/components/modals/__tests__/impersonate-user-modal-integration.spec.tsx
Tests validate custom groups, unavailable group data, duplicate prevention, helper text, submission values, and username-only impersonation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 96ff2

This change enables free-form group entry when group resources are unavailable while preserving existing selection behavior; no actionable merge-blocking risk remains after normal checks and review.

Hi @platex-rehor-bot. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Use the actual no-model load state in model-absent tests.

useK8sWatchResource returns [[], true, NoModelError] when model discovery completes without a Group model. These tests use loaded = false, so they model a pending or failed watch instead. Keep the false state in the generic load-error test. Use true for tests that claim the Group model is absent.

you need to run yarn i18n since there are new translation strings. Thats why frontend CI job is failing.

Thanks @jhadvig! Good catch — I ran yarn i18n and pushed the updated translation strings (c054b3e). The frontend CI should pass now.

OCPBUGS-112263
When Direct Authentication (external OIDC) is enabled, the
group.openshift.io model does not exist and the impersonation modal
fails with "Model does not exist". Replace the hard-coded enumerated
group selector with a creatable typeahead that supports both:
- selecting from API-discovered groups (when available)
- free-form entry of group names via Enter key or "Create" option

This preserves multi-group impersonation and gracefully degrades when
the Group model is absent, showing helper text instead of an error.

Hey @platex-rehor-bot 👍

ci/prow/frontend is failing with 2 ESLint errors in impersonate-user-modal.tsx:

1. @typescript-eslint/no-use-before-define (line 55)
ImpersonateUserModalContent is referenced in the ImpersonateUserModal component before it's defined below. Either move ImpersonateUserModalContent above ImpersonateUserModal, or add an eslint-disable comment if the ordering is intentional.

2. prettier/prettier (line 123)
Formatting mismatch in the availableGroups.some() callback:

123:48  error  Replace `⏎······(g)·=>·g.toLowerCase()·===·trimmed.toLowerCase(),⏎····` with `(g)·=>·g.toLowerCase()·===·trimmed.toLowerCase()`

Running yarn eslint --fix on the file should auto-fix this one.

Also, this PR removes 2 useEffect-with-setState patterns, which drops the lint warning count from 342 to 340. The custom eslint-exact-warnings.js formatter enforces an exact match, so you'll also need to update MAX_WARNINGS in frontend/package.json from 342 to 340.
