Flask-AppBuilder SecurityManager for OpenIDConnect

Flask-AppBuilder SecurityManager for OpenIDConnect

Wrapper for flask_oidc that exposes a SecurityManager for use with any Flask-AppBuilder app.

It will allow your users to login with OpenIDConnect providers such as Auth0, Okta or Google Apps.

This is roughly inspired by the code in this stackoverflow answer. (MIT Licenced © thijsfranck)

Usage

Generic

Just override the default security manager in your Flask Appbuilder app.

from fab_oidc.security import OIDCSecurityManager

appbuilder = AppBuilder(app, db.session, security_manager_class=OIDCSecurityManager)

Airflow

Airflow provides a hook in the webserver_config.py file where you can specify a security manager class. In webserver_config.py import the OIDCSecurityManager and set

from fab_oidc.security import AirflowOIDCSecurityManager
...
SECURITY_MANAGER_CLASS = AirflowOIDCSecurityManager

Airflow now requires that your SECURITY_MANAGER_CLASS is a subclass of AirflowSecurityManager. Use the special AirflowOIDCSecurityManager that is only defined if you're using this library alongside Airflow.

Superset

Superset works in a a similar way. Just as in Airflow, SECURITY_MANAGER_CLASS needs to be a subclass of SupersetSecurityManager the config is in a file called superset_config.py and the hook is called CUSTOM_SECURITY_MANAGER. There now exists a special SupersetOIDCSecurityManager that is only defined if you are using this library alongside Superset.

from fab_oidc.security import SupersetOIDCSecurityManager
...
CUSTOM_SECURITY_MANAGER = SupersetOIDCSecurityManager

Settings

The settings are the same as the flask_oidc settings, so look there for a reference.

if you're happy with flask_oidc's defaults the only thing you'll really need is something like:

OIDC_CLIENT_SECRETS = '/path/to/client_secret.json'

see the flask_oidc manual client registration docs for how to generate or write one.

OIDC Field configuration

If you like to change the default OIDC field that will be used as a username, first name and last name you can set the following env var in the shell you run your process:

export USERNAME_OIDC_FIELD='preferred_username'
export FIRST_NAME_OIDC_FIELD='given_name'
export LAST_NAME_OIDC_FIELD='family_name'
