# Plan 02-04: LDAP Integration — Summary

**Status:** Complete
**Date:** 2026-06-19

## What Was Built

### Task 1: Backend LDAP Module
- LdapService using ldapts library for directory sync (NOT as auth — anti-pattern avoidance)
- LdapConfigService for per-tenant LDAP configuration (D-18)
- LdapSyncScheduler with configurable auto-sync interval (D-14)
- Field mapping: configurable with defaults (displayName→Name, mail→Email, sAMAccountName→Username) (D-16)
- Custom field mapping support (D-17)
- Deactivation of removed LDAP users (D-15)
- Manual sync endpoint POST /ldap/sync
- Prisma schema extended with LdapConfig and LdapFieldMapping models

### Task 2: Frontend LDAP Admin UI
- LDAP settings page at /admin/ldap
- Connection configuration form (server URL, base DN, bind user, filter)
- Field mapping editor with default + custom fields
- Test connection button
- Manual sync trigger button
- Sidebar navigation updated with LDAP admin link
- i18n keys for DE/EN

## Commits
- `f928cd7`: LdapModule with sync service, config service, scheduler, controller
