radicaleconf

Radicaleconf is the configuration file used by Radicale, an open-source server that implements CalDAV and CardDAV protocols for synchronizing calendars and contacts. The file is read by the Radicale process at startup to determine how the server should listen for requests, where data is stored, who can access it, and how logs are recorded. The file is commonly named radicale.conf and its location varies by installation; it may reside under /etc/radicale/, in a virtual environment, or in a user-specific configuration directory.

The file uses a simple, section-based syntax. Each section begins with a name in square brackets and contains key = value pairs. Lines starting with # are comments. The available sections differ by version, but typical sections include [server], [storage], [auth], [rights], [logging], and [ssl]. The [server] section configures the network interface and port (for example, hosts = 0.0.0.0:5232). The [storage] section selects the backend (such as filesystem) and its parameters (like a path to the data). The [auth] section defines authentication methods (for example htpasswd) and related files. The [rights] section controls access to resources. The [logging] and [ssl] sections adjust log output and TLS settings, respectively.

After editing radicale.conf, the Radicale service typically needs to be restarted or reloaded for changes to take effect. As with any security-sensitive configuration, access to radicale.conf should be restricted to trusted administrators, and TLS should be used in production. Documentation and sample configurations vary by release, so consult the official Radicale project documentation for the version in use.
