- Resolved 7 Pylance errors in identity shard (async/to_thread misuse, missing AD adapter methods) - Remapped search_users, get_stale_accounts, get_disabled_accounts, get_user_by_email call sites - Added structured logging to identity shard - Verified 0 diagnostics and 19/19 unit tests passing - Live mock validation: status reconciliation, disabled accounts, audit log queries - Deferred: WIS-018 (get_groups backend method), field-name alignment audit

# Session snapshot — 2026-04-15
|
|
|
|
**Branch:** main
|
|
**Commit:** f4ec8b1 — feat: implement AD backend aliases and fix identity shard async calls (#3)
|
|
**Status:** ✅ Committed and pushed to origin/main
|
|
|
|

|
|
|
|
## Session goals
|
|
|
|
Resolve all 7 active Pylance diagnostics in the identity shard caused by
|
|
call-site mismatches between identity.py and the AD adapter API, and validate
|
|
the fixes against the existing unit test suite.
|
|

## Accomplishments
|
|
|
|
- **Diagnosed 7 Pylance errors** across two error classes:
|
|
- `CoroutineType not assignable` — asyncio.to_thread wrapping async methods
|
|
- `Attribute unknown` — call sites referencing methods not on the adapter class
|
|
|
|
- **Fixed async call semantics (identity.py)**
|
|
- Removed all `asyncio.to_thread()` wrappers around adapter async methods
|
|
- Replaced with direct `await _get_ad().<method>(...)` calls
|
|
- Resolved: `ad_get_user` (line 60), `ad_get_group_members` (line 120)
|
|
|
|
- **Remapped missing method calls (identity.py)**
|
|
- `search_users` → `search_users_by_name` (method renamed in adapter)
|
|
- `get_stale_accounts` → `find_stale_users` (method renamed in adapter)
|
|
- `get_disabled_accounts` → `query_users(filter_params={"enabled": False})`
|
|
- `get_user_by_email` → bounded `query_users` page scan + in-memory email match
|
|
- `get_groups` → temporary empty-list fallback + `logger.warning` + WIS-018 TODO
|
|
|
|
- **Preserved tool contracts** — `ad_get_group_members` keeps `list[dict]` return type;
|
|
backend `list[str]` usernames are wrapped as `{"sAMAccountName": u}` objects
|
|
|
|
- **Added structured logging** — `import logging` + `logger = logging.getLogger(__name__)`
|
|
added to identity shard; warning emitted when unimplemented group listing is called
|
|
|
|
- **Verified: 0 Pylance diagnostics** — confirmed via VS Code language server
|
|
- **Verified: 19/19 unit tests passing** — `tests/identity_tests/test_ad_adapter.py`
|
|
|
|
- **Live tool validation (mock mode)**
|
|
- `scan_status_reconciliation` — detected EMP002 (Taylor Brooks) terminated in
|
|
Workday but still enabled in AD
|
|
- `ad_get_disabled_accounts` — returned David Kim (EMP-1004, UAC 514)
|
|
- `nexus_audit_recent` — confirmed 13 clean READ-only audit entries, no errors
|

## Technical debt / pending
|
|
|
|
| ID | Item | Priority |
|
|
| :--- | :--- | :---: |
|
|
| WIS-018 | Add `get_groups()` to `ActiveDirectoryIdentityBackend` to replace empty-list fallback in `ad_list_groups` | Medium |
|
|
| — | `ad_get_user_by_email` uses a full paginated scan; add a dedicated AD `mail` filter method in the backend if directory size becomes a latency concern | Low |
|
|
| — | `ADUserAdapter.to_canonical` reads raw LDAP field names (`sAMAccountName`, `mail`); the query_users email path returns normalized field names — field-name alignment between adapter and canonical transformer should be reviewed in a future pass | Low |
|
|
|

|
## Next steps
|
|
|
|
1. **WIS-018 — Add `get_groups()` to ad_adapter.py**
|
|
- Use `Get-ADGroup -Filter *` with `Name`, `DistinguishedName`, `GroupCategory` properties
|
|
- Follow the existing `find_stale_users` pattern (PowerShell → JSON → normalized list)
|
|
- Add unit test in `tests/identity_tests/test_ad_adapter.py`
|
|
- Remove the temporary fallback + TODO from `ad_list_groups` in identity.py
|
|
|
|
2. **Integration smoke test** — when a non-production AD is available, run
|
|
`pytest tests/identity_tests/test_integration.py -v` with `AD_TEST_USERNAME`
|
|
and `AD_TEST_PASSWORD` set
|
|
|
|
3. **Field-name audit** — trace `query_users` output keys through `ADUserAdapter.to_canonical`
|
|
to confirm the email-scan path in `ad_get_user_by_email` produces a valid canonical object
|
