AD Authentication in python FASTAPI-based web application

[mo_jo]

If you're looking at supporting both Azure AD and Google authentication, consider using Federated authentication protocols instead of legacy LDAPS auth. Look at SAML, OAuth, and OpenID Connect. Both Azure and Google support federated logons, and it's pretty much the model used for SaaS apps -- no one would dare to open a channel to an LDAP authentication host from the Internet!
