This sample plugin demonstrates how to perform gateway authentication via a custom plugin for SPS-initiated sessions while using SPP as the credential store.

The example code in plugin/plugin_bare.py demonstrates how to read the identity_provider property from the plugin configuration. It then prompts the user to enter a user name and password, which can be used to authenticate the user with a third-party authentication provider. The identity_provider value must be set in the session cookie to pass the information to SPP. It should match the identity provider name configured in SPP when it was added.
