#### LDAP enabled variant
In the images tagged with "-ldap" you can authenticate netbox against an LDAP / AD server. The included ldap_config.py is configured to use an AD domain controller. The custom values can be injected with environment variables like those in the main configuration file.
### Production
The default settings are optimized for (local) development environments.
