Radicale can be extended by plugins for authentication, rights management and storage. Plugins are python modules.

Getting started

To get started we walk through the creation of a simple authentication plugin, that accepts login attempts if the username and password are equal.

The easiest way to develop and install python modules is Distutils. For a minimal setup create the file setup.py with the following content in an empty folder:

#!/usr/bin/env python3

from distutils.core import setup

setup(packages=["silly_auth_plugin"])

In the same folder create the sub-folder silly_auth_plugin. The folder must have the same name as specified in packages above.

Create the file \_\_init\_\_.py in the silly_auth_plugin folder with the following content:

from radicale.auth import BaseAuth

class Auth(BaseAuth):
    def is_authenticated(self, user, password):
        self.logger.info("Login attempt by '%s' with password '%s'",
                         user, password)
        return user == password

Install the python module by running the following command in the same folder as setup.py:

python3 -m pip install --upgrade .

To make use this great creation in Radicale, set the configuration option type in the auth section to silly_auth_plugin.

Authentication plugins

This plugin type is used to check login credentials. The module must contain a class Auth that extends radicale.auth.BaseAuth. Take a look at the file radicale/auth.py in Radicale's source code for more information.

Rights management plugins

This plugin type is used to check if a user has access to a path. The module must contain a class Rights that extends radicale.auth.BaseAuth. Take a look at the file radicale/rights.py in Radicale's source code for more information.

Storage plugins

This plugin is used to store collections and items. The module must contain a class Storage that extends radicale.auth.BaseStorage. Take a look at the file radicale/storage.py in Radicale's source code for more information.
