# Shaarli configuration

Once your Shaarli instance is installed, the file `data/config.json.php` is generated:

- it contains all settings in JSON format, and can be edited to customize values
- it defines which [plugins](Plugins.md) are enabled
- its values override those defined in `index.php`
- it is wrapped in a PHP comment so that its contents are never served by the web server, regardless of configuration

**Do not edit configuration options in index.php! Your changes would be lost.**

## Tools menu

Some settings can be configured directly from a web browser by accesing the `Tools` menu. Values are read/written to/from the configuration file.

### LDAP

- **host**: LDAP host used for user authentication
- **dn**: user DN template (`sprintf` format, `%s` being replaced by user login)
