"""
Example Custom SSO Handler
Use this if you want to run custom code after litellm has retrieved information from your IDP (Identity Provider).
Flow:
- User lands on Admin UI
- LiteLLM redirects user to your SSO provider
- Your SSO provider redirects user back to LiteLLM
- LiteLLM has retrieved user information from your IDP
- Your custom SSO handler is called and returns an object of type SSOUserDefinedValues
- User signed in to UI
