Are there any libraries that are supported in App Engine Standard Python architecture to provide SAML 2.0 support?
This post suggests using App Engine Flex and the python-saml library using a Docker image: python SAML in GAE
I've tried this method, but you lose out on some of the Standard-only features like the X-Appengine-Inbound-Appid header, which is stripped when making calls from a Flex environment, and using the native Datastore is more of a pain.
If there are no Python-native libraries currently supported in AES-Python, do one of the other standard-supported languages (Java, PHP, Go) have a native solution for SAML 2 SSO integrations that I could spin up as a separate service?
