There are two methods for authentication listed in the REST API documentation: https://learn.microsoft.com/en-us/azure/cognitive-services/openai/reference
I see that an Azure policy (https://github.com/Azure/azure-policy/blob/master/built-in-policies/policyDefinitions/Cognitive%20Services/CognitiveServices_DisableLocalAuth_Audit.json) supports disabling local authentication for the type “Microsoft.CognitiveServices/accounts”.
I would only like people to use Azure Active Directory authentication. Would I be able to ensure this (AAD) is the only option used with the built-in policy?
