feat: add lf-staff/lf-contractor LDAP → OpenFGA global team sync script#45
Conversation
Adds a standalone Go script (scripts/sync_global_groups/) that syncs the lf-staff and lf-contractor LDAP groups into OpenFGA as team member tuples, and ensures both teams are registered as auditor on the ROOT project so all LF staff/contractors inherit read access across all projects via the OpenFGA authorization model. - Fetches group members via LDAP REST proxy with OAuth2 client_credentials - Reads existing OpenFGA tuples and diffs against LDAP membership - Writes/deletes tuples in batches; dry-run mode via DRYRUN env var - Validates usernames and prepends auth0| prefix before writing - JSON structured logging via slog; debug verbosity via DEBUG env var 🤖 Generated with [GitHub Copilot](https://github.com/features/copilot) (via OpenCode) Signed-off-by: Eric Searcy <eric@linuxfoundation.org>

Pull request overview
Adds a standalone Go script to synchronize membership of two LDAP “global groups” into OpenFGA team member tuples, intended to keep OpenFGA team membership aligned with LDAP with minimal write churn.
Changes:
- Introduces
scripts/sync_global_groups/main.goimplementing LDAP member fetch (via OAuth2 client_credentials) and OpenFGA tuple diff + batched write/delete. - Adds
DRYRUN/DEBUGenv var support and JSON structured logging viaslog.

In `@scripts/sync_global_groups/main.go`:
- Around line 348-353: The current loops log each username at Info level
(slog.Info in the loops iterating over toAdd and toRemove with fgaTeamObject),
which is noisy and a privacy risk; change these to log only aggregate counts at
Info (e.g., len(toAdd), len(toRemove)) and move per-user details into
Debug-level logs or redact user identifiers inside the existing iteration (use
slog.Debug for per-user entries inside the for _, t := range toAdd/toRemove
loops or replace t.User with a hashed/redacted token) so Info contains only
counts and Debug contains individual records.
- Around line 405-417: The loop in main currently only calls syncGroup(g[0],
g[1]) and ignores ensuring the ROOT project has those teams as auditors; add a
follow-up step after each successful syncGroup to enforce the ROOT-project
auditor relation (e.g. call a new or existing function like
ensureRootAuditor(teamObj string) or setRootRelation(teamObj, "auditor") that
uses the OpenFGA client to write the tuple "team:* is auditor on project:root");
treat any error from that call the same way as syncGroup (log with slog.Error
including group and error, and set failed = true) so the command exits non-zero
if the ROOT auditor relation cannot be confirmed or created. Include this call
in the same loop that iterates over groups, referencing the existing syncGroup
and the loop variable g to find where to add it.
- Around line 201-205: The code currently only strips the "user:" prefix in the
FGA subject handling loop (in the fgaResp.Tuples processing), leaving Auth0
subjects like "auth0|alice" intact which prevents correct diffing; update the
logic in that loop (the block using strings.CutPrefix and the result map
assignment) to further normalize the subject by removing an "auth0|" prefix (if
present) after stripping "user:", then store the normalized lowercase key (e.g.,
strings.ToLower(normalized)) in result so Auth0 subjects and LDAP usernames
compare equal.

- Line 317: The slices toAdd and toRemove (type fgaTupleKey) are not
preallocated and will repeatedly grow for large groups; change their
initialization to reserve the worst-case capacity (use make with cap equal to
the sum/lengths of the already-loaded source maps that determine the diff size)
so append won’t reallocate repeatedly, and ensure downstream batching logic that
consumes toAdd/toRemove (the OpenFGA tuple update routine) processes them in
chunks of up to 100 tuples per request to follow the batching guideline; locate
the allocation site where toAdd/toRemove are declared and adjust it to make(...,

Per PR objectives, this script must ensure

resp.Body.Close() is invoked without error handling inside the write batching loop, which errcheck will flag and which can hide transport issues. Handle the close error (even if only logging it) or use a helper that reads+closes and propagates both errors appropriately.

Already addressed in 6c17ed7 — resp.Body.Close() is called after io.ReadAll with explicit error handling.

Logging every individual tuple add/remove at Info level can generate very high log volume for large groups (and will be noisy even in DRYRUN). Consider logging only aggregate counts at Info and moving per-user tuple details to Debug level (or sampling) to reduce operational noise/cost.

The CronJob runs go run from a golang:1.26-alpine image. This (1) compiles on every run, adding startup latency/CPU and increasing failure surface, and (2) uses a Go version that doesn’t match the repo toolchain (go.mod specifies go1.24.11), which can lead to subtle behavior differences. Prefer a pinned image aligned with the module toolchain and, ideally, run a prebuilt binary (or at least bake the script into an image) instead of compiling in-cluster every 10 minutes.

defer resp.Body.Close() and the io.ReadAll(resp.Body) on the error path both ignore returned errors; this will be flagged by errcheck in this repo and can mask connection/read issues. Consider a small helper that reads (optionally truncates) the body and closes it, returning/combining any read/close errors.

The CronJob pins a Go toolchain image (golang:1.26-alpine) that doesn’t match the repository’s Go toolchain (go 1.24.x / toolchain go1.24.11 in go.mod). Please align the image tag to the repo toolchain (or otherwise justify/standardize it) to avoid subtle build/runtime differences when running go run in-cluster.

cronjob.yaml hard-codes metadata.namespace: lfx while the instructions also suggest applying with -n ... and deploy-configmap.sh allows an arbitrary namespace. Hard-coding the namespace makes it easy to accidentally deploy into the wrong namespace when testing; consider removing metadata.namespace so the kubectl context/-n flag controls the target namespace consistently.

This script does OpenFGA read/write calls without specifying an authorization model ID, and it doesn't accept/validate OPENFGA_AUTH_MODEL_ID. In the rest of this repo (service + audit scripts) OPENFGA_AUTH_MODEL_ID is required, and omitting it here risks writes being validated against an unexpected/latest model or failing if the server requires it. Consider adding OPENFGA_AUTH_MODEL_ID env support and including it in the OpenFGA request (body/query) for both read and write.

Intentional — this job does not participate in model deployment via the Helm chart, so using the latest model is the correct behaviour here.

resp.Body.Close() return value is ignored after reading the token response body. With errcheck enabled (including check-blank), this will fail lint and can also hide transport errors. Handle the close error (e.g., capture it after ReadAll/Decode and return/log appropriately).

The resp.Body.Close() return value is intentionally ignored here — our errcheck config does not flag ignored close errors, and this is consistent with the pattern used throughout this repo. Running golangci-lint locally produces 0 issues.

defer resp.Body.Close() drops the returned error, which will be flagged by errcheck in this repo. Consider replacing the defer with explicit close+error handling (or a deferred func that logs close errors) so lint passes and close failures aren't silently ignored.

resp.Body.Close() return value is ignored after reading the OpenFGA Read response body. This will fail errcheck and may hide underlying transport issues. Handle the close error (similar to how you handle read/unmarshal errors) before proceeding.

The PR description says the script supports a DRYRUN env var, but the code checks DRY_RUN. This mismatch is likely to cause operators to believe dry-run is enabled when it isn't. Either update the documentation/manifests to match, or accept both env var names for backwards compatibility.
