OpenID Connect demo
This is a demo app for the OIDC authentication code flow in a command line tool.
The tool constructs the authentication flow and redirects the user's browser to the single sign-on page. It starts a tornado webserver to handle the OIDC redirect. After the callback arrives it requests an access token and basic user info.
Supported flows:
- authentication code flow (confidential clients)
- authentication code flow with PKCE (public clients)
Installation
To install all dependencies with conda or mamba:
conda env create -f environment.yml
There is also an environment_dev.yml
file with includes some recommended linters for developing.
Alternatively, install dependencies listed in the the above file manually with pip.
Client setup
The client should be registered out-of-band. You will need the following information:
- The issuer. This should be an https url, and there should be a valid configuration file at {issuer}/.well-known/openid-configuration
- Client ID
- Client Secret (or PKCE)
The redirect URL must be registered with the issuer as http://0.0.0.0:18546/auth (port can be customized if needed).
Usage
Parameters can be specified at the command line or as environmental variables. For instance,
export OIDC_CLIENT_ID=...
export OIDC_CLIENT_SECRET=...
export OIDC_ISSUER=...
python oidc_test.py
Public access clients should specify 'PKCE' for the client secret.
