Quick Task 260729-d3k: LDAP Multi-Base-DN & Base-DN-as-Scope Summary

Replaced the "empty group filter = sync nothing" model from Quick 260728-lih with a "Base-DN(s) = sync scope" model: the Base-DN admin field now accepts multiple newline-separated DNs, all three LDAP directory-search paths loop and merge every configured base, and the mass-deactivation safety guard is re-keyed to the parsed base-DN list instead of groupFilterDns.

Performance

• Duration: ~3 min
• Started: 2026-07-29T07:34:57Z
• Completed: 2026-07-29T07:38:16Z
• Tasks: 2/2 completed
• Files modified: 5

Accomplishments

• parseBaseDns() splits the single baseDn String column (still no schema/migration change) into a trimmed, non-empty DN list, dropping blank/whitespace-only lines.
• syncUsersForTenant()'s early-return no-op guard is now keyed exclusively on parseBaseDns(config.baseDn).length === 0 — the sole condition that skips bind/search and the deactivation loop. An empty groupFilterDns no longer triggers a no-op; it now performs a normal multi-base search with no memberOf restriction.
• collectSearchEntries(), listGroups(), and searchUsers() all loop over every configured base DN and merge/dedupe results into a Map<string, Entry> keyed by entry.dn. groupFilterDns remains an optional extra restriction: ou= entries become additional search bases (plain filter), non-ou= entries become an optional memberOf OR-clause ANDed onto every base-DN search.
• Admin LDAP page's Base-DN field is now a multi-line <textarea rows={3}> (was a single-line <input>), with a baseDnHint paragraph underneath. The bound value stays one plain string with newline separators — fetchConfig/handleSave were untouched.
• de/en i18n reworded: groupFilter.description and groupFilter.emptyMeansAll now describe the group filter as an optional additional restriction and state that an empty selection syncs all users under the Base-DN(s) — the old "nothing is synced" framing is gone. New baseDnHint key added to both locales.

Task Commits

Each task was committed atomically:

1. Task 1: Backend multi-base scope + base-DN-keyed deactivation guard + spec - 5cbd530 (feat)
2. Task 2: Multi-line Base-DN textarea + reworked de/en i18n - 96be7e1 (feat)

Plan metadata: pending (docs commit follows, handled by orchestrator)

Note: This plan had tdd="true" on Task 1's frontmatter, but the plan's own <action> text specified writing/updating tests alongside the implementation change rather than a strict RED→GREEN cycle (this is a refactor of existing tested behavior, not new-feature TDD). Both the implementation and spec changes were committed together in a single feat commit, consistent with how the task's <verify>/<done> criteria were framed (spec pass + type-check, not a RED-then-GREEN gate sequence).

Files Created/Modified

• apps/api/src/ldap/ldap.service.ts - Added parseBaseDns(); re-keyed syncUsersForTenant()'s no-op guard; rewrote collectSearchEntries(), listGroups(), searchUsers() to loop and merge every configured base DN
• apps/api/src/ldap/ldap.service.spec.ts - Replaced the "empty selection no-op" describe block with an "empty base DN no-op" block (plus a second spec proving empty-groupFilterDns is NOT a no-op); added a "multi base DN scope" describe block with a two-base merge/dedup spec
• apps/web/src/app/(portal)/admin/ldap/page.tsx - Base-DN <input> replaced with a multi-line <textarea rows={3}> + hint paragraph
• apps/web/src/messages/de.json - Added baseDnHint; reworded groupFilter.description/emptyMeansAll
• apps/web/src/messages/en.json - Added baseDnHint; reworded groupFilter.description/emptyMeansAll

Decisions Made

• The no-op guard is keyed SOLELY on the parsed base-DN list being empty — this is the one and only condition under which syncUsersForTenant skips search and the deactivation loop, per the plan's CRITICAL SAFETY requirement.
• ou= group-filter entries remain additional search bases; non-ou= entries remain an optional memberOf constraint — unchanged in substance from the prior Quick 260728-lih logic, just now applied across every configured base DN instead of the single config.baseDn.
• No controller change: ldap.controller.ts still passes config.baseDn as a plain String into listGroups/searchUsers — the service splits it internally.

Deviations from Plan

None - plan executed exactly as written. All five files listed in the plan's files_modified frontmatter were touched, and no others (schema.prisma, ldap-sync.scheduler.ts, auth.service.ts, ldap.controller.ts were explicitly left untouched per the plan's critical notes).

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All 18 ldap.service.spec.ts specs pass (up from the prior file's spec count, +5 net new/changed specs: empty-base-DN no-op, non-no-op-with-empty-groupFilterDns, multi-base merge/dedup).
• Full API suite: 396/396 tests pass (pnpm --filter @tessera/api exec vitest run).
• pnpm --filter @tessera/api run type-check and pnpm --filter @tessera/web run type-check both clean.
• de.json/en.json parse as valid JSON and carry the reworded scope wording plus the new baseDnHint key.
• No Prisma schema change, no migration, no new endpoint, no Dockerfile/infra change — git diff for this quick task touches exactly the five files listed in the plan.
• Live UI rendering of the new textarea was not visually verified in a browser during this quick task (see coverage.D4.rationale); it is a low-risk mechanical swap (input type="text" → textarea) with the same bound state and unchanged save/fetch logic.
