Cannot Authenticate to Azure Functions with Azure Active Diectory Bearer Token

Question

I am trying to make the AAD auth to work with my Azure Functions, but I keep having 401s... My front end calls the azure functions with a Bearer token forge from the Front-End AAD AppId requesting access through adal.AuthenticationContext.acquireToken("Azure Functions AAD AppId"). On the Azure Portal, I configured the Auth to use AAD with the same AppId. Either in Express or Advanced mode, I cannot make this work and I always receive 401... If I switch my functions to Level.Function, then this works if I pass over the token in the Http call (but I rather use AAD !!!) Thanks for your insight, Regards Adrien

Answer 1

Try to change the level to Anonymous.
