Hey @Milosz_Kowalski I was able to use the “saml” package in functions, so I’d recommend to try doing what you wanted to do with saml and let me know if you have specific errors coming up. I don’t have valid saml options to test this out fully though. There’s also @node-saml/passport-saml which might also help as an alternative if you end up being blocked with what you want to accomplish now.
Regarding the link that’s the drivers doc not app services which doesn’t use a custom Node engine like we do for App Services Functions.
