Aufgabe 2 der Etappe 2: getConfig/createConfig/updateConfig sowie
addFieldMapping/removeFieldMapping laufen jetzt ueber forTenant(), gebunden
an den aus der Anfrage bekannten Mandanten. removeFieldMapping nimmt den
Mandanten neu als Pflichtparameter entgegen und der Controller holt ihn aus
dem Sitzungsnachweis statt nur die URL-Kennung weiterzureichen (T-IPC-01) --
ein Administrator konnte bisher die Feldzuordnung eines fremden Mandanten
loeschen, wenn er ihre Kennung kannte. getAllActiveConfigs() und die
Start-Nachverschluesselung bleiben bewusst uebergreifend, mit ausgeschriebener
Begruendung im Code (Befund B).
rls-access-inventory.spec.ts erkennt jetzt neben `this.prisma.<Modell>` auch
gebundene `<Name>.<Modell>`-Zugriffe (Befund F/G) und prueft eine neue
Stand-Spalte (gebunden/ungebunden/gemischt) im Klassifikationsdokument gegen
den Quelltext. Das macht zwei bisher unsichtbare, weil schon laenger
gebundene Fundstellen sichtbar (auth.service.ts/passwordResetToken,
ldap.service.ts/groupMembership) und deckt auf, dass
(ldap-config.service.ts, ldapConfig) tatsaechlich "beides" ist, nicht
"muss-mandantengebunden" (Befund B).

Task 1 checkpoint resolved: approve-both, granted 2026-08-06 by the
project owner (D-04 one-way schema extension: Group.internalName +
Group.ldapObjectGuid, both nullable, one versioned migration).
Adds the Phase 16 tracer slice through every layer:
- Prisma schema: Group.internalName, Group.ldapObjectGuid,
@@unique([tenantId, ldapObjectGuid]) (Prisma client regenerated;
the versioned migration itself is Task 3, separately blocking).
- LdapService: listGroups() now reads objectGUID via
explicitBufferAttributes and flags alreadyImported per tenant;
new importGroupsByDn() creates a Group per checked DN with
name/ldapDn/ldapObjectGuid, reject-with-report on name collision
(P2002 on name -> nameCollisions, P2002 on ldapObjectGuid ->
skipped), never aborts the batch on one DN's error; new static
escapeLdapFilterBuffer() for Plan 16-03's later existence sweep.
- DTO/controller: ImportGroupsDto, POST /ldap/groups/import
(ADMIN/SUPER_ADMIN), listGroups route now tenant-scoped.
- Frontend: new "AD-Gruppen importieren" section in /admin/ldap,
own discovery/import handlers with a visible error state
(Owner decision 2026-08-06 — no silent catch{} for these two
handlers), i18n keys in de.json/en.json.
- Tests: 8 new cases covering the full <behavior> list plus
listGroups sort order and alreadyImported.
Flagged assumption (RESEARCH.md A1/A2): objectGUID rename-stability
and the binary filter syntax are unverified against a real AD —
this plan only WRITES the GUID, Plan 16-03 reads it back live.
Add a per-tenant "Skip TLS certificate verification" toggle to the LDAP
admin page so admins can connect to an AD whose ldaps:// certificate is
signed by an internal/self-signed CA (Node error: "unable to verify the
first certificate"). When enabled, ldapts is given
tlsOptions.rejectUnauthorized=false; the flag is ignored for plain ldap://
(no TLS). Defaults to full verification.
New Boolean column LdapConfig.tlsRejectUnauthorized (@default(true)) +
migration; wired through DTOs, config service, all Client creations
(test/groups/user-search/import/sync) and the test-connection endpoint. UI
checkbox with an insecure-network warning (de/en). 3 new service specs;
API 218 green, web 131 green, both apps tsc clean.

Add an AD single-user search (by cn/sAMAccountName/displayName/mail) and a
selective import to the LDAP admin page, alongside the existing group/OU
filter. Imported users are deduped against existing ones by (ldapDn, then
username): a manually-imported user carries its ldapDn, so a later
department/group sync matches and updates it in place instead of creating a
duplicate. Search results flag alreadyImported; import skips existing users
and links a missing ldapDn. Extracted shared mapEntry/upsertMappedUser
helpers so sync and manual import resolve identity identically.
Backend: GET /ldap/users/search, POST /ldap/users/import (RFC-4515 escaped
query, ADMIN-guarded). 6 new service specs (search flags, create, skip,
ldapDn-link, denylist). Full API suite 215 green, both apps tsc clean.

Add a per-username denylist so individual accounts (service accounts like
administrator, krbtgt, guest, ldap$) can be excluded from LDAP sync,
independent of the group/OU include-filter which only scopes the search.
- schema: LdapConfig.userExcludeList String[] (+ migration)
- sync: skip excluded usernames (case-insensitive) before recording the DN,
so an already-imported user added to the list gets deactivated next sync
- DTO / config service / controller / scheduler: thread userExcludeList through
- web: exclude-list admin UI section (add/remove/save) + de/en translations
- tests: 3 specs covering empty list, case-insensitive skip, deactivation

bindDn and bindPassword are now optional on LdapConfig (nullable
migration) and throughout the DTOs/service/client -- an admin can
leave both blank to connect to directories that permit anonymous
read access. LdapService.bind() falls back to an RFC 4513 anonymous
bind (empty DN + empty password) whenever either field is missing,
shared across testConnection, listGroups, and syncUsersForTenant.
Frontend: removed the required attribute from Bind-DN/Bind-Passwort,
added a placeholder hint ("leer = anonymous bind"), and the
"Verbindung testen" button now only needs a Server-URL to enable
(not bindDn+bindPassword). Config responses now return bindPassword
as null (not a misleading "********") when no password is set.
Verified locally: submitted only a Server-URL with both bind fields
empty and confirmed the request reached the anonymous-bind code path
(DNS failure for the unreachable test host, not a validation error).

"Verbindung testen" only appeared after a config was already saved,
so a fresh/never-configured tenant had no way to validate connection
details at all. Now the button is always visible; POST /ldap/test-connection
accepts optional ad-hoc serverUrl/bindDn/bindPassword and falls back
field-by-field to the saved config for anything omitted (bindPassword
in particular, since the form never re-sends the masked saved password).
Verified locally: tested with typed-but-unsaved values (base DN left
blank, nothing saved) and got a real connection attempt/error back,
not a 404 "no config" response.

Adds listGroups() to browse AD groups/OUs under base DN, and
collectSearchEntries() to restrict syncUsersForTenant to members of
selected groups or users under selected OUs. Group DNs are matched
via escaped memberOf clauses (RFC 4515); OU DNs become extra search
bases. Empty groupFilterDns keeps the original single-base-DN search
unchanged. Controller sync endpoint and the sync scheduler both pass
groupFilterDns through so manual and scheduled syncs honor it.
