LDAP Configuration

The LDAP integration supports standard Active Directory and OpenLDAP setups:

# LDAP Server URL
LDAP_URL=ldap://ldap.example.com:389

# Base DN for user search
LDAP_BASE_DN=ou=users,dc=example,dc=com

# Bind DN for searching (if needed)
LDAP_BIND_DN=cn=admin,dc=example,dc=com
LDAP_BIND_PASSWORD=admin_password

# Custom search filter (optional)
LDAP_SEARCH_FILTER=(uid={{username}})

Users authenticate with their LDAP username and password.

Development

# Run in development mode
npm run dev

# This starts:
# - Backend server on port 3000 (with hot reload)
# - Vite dev server on port 5173 (with HMR)
# - Proxy from Vite to backend for /api and /v1

Production Deployment

# Build frontend
npm run build

# Start production server
NODE_ENV=production npm start

The production server serves static files from dist/ and handles all API routes.
