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
