+### How can I setup LDAP authentication?
+
+LDAP authentication is disabled by default. To use it, you will need to install [PHP LDAP extension](https://www.php.net/manual/en/book.ldap.php) and edit your `lib/config.local.php` to set those options:
+- `upload_ldap_auth`: set it to `true`
+- `upload_ldap_host`: set it to your ldap host
+- `upload_ldap_base_dn`: set it to your base DN
+
+More details in [config.original.php](lib/config.original.php)'s documentation.
+
+Note that you can test around LDAP with [docker-compose example](./docker/docker-compose-examples/ldap/).
