Radicale is compatible with the WSGI specification. Use `radicale.wsgi` from
the source code as the WSGI file.

A configuration file can be set with the `RADICALE_CONFIG` environment variable,
otherwise no configuration file is loaded and the default configuration is used.

Be reminded that Radicale's default configuration enforces limits on the
maximum upload file size.

**Security:** The `None` authentication type disables all rights checking.
Don't use it with `REMOTE_USER`. Use `remote_user` instead.

## Manage user accounts with the WSGI server
Set the configuration option `type` in the `auth` section to `remote_user`.
Radicale uses the user name provided by the WSGI server and disables
authentication over HTTP.
