Recommended action: Use api-key header for keys (AzureOpenAI(api_key=...)), or azure_ad_token_provider with scope https://cognitiveservices.azure.com/.default (cloud-specific for sovereign clouds); refresh tokens via a provider rather than a static token. Option: Match auth header/scope to credential type [evidence: documented_workaround] Applies when: Azure OpenAI clients Steps: 1. Keys: send api-key header (use AzureOpenAI client, not a generic OpenAI client with Bearer) 2. Entra: get_bearer_token_provider(cred, "https://cognitiveservices.azure.com/.default") 3. Sovereign clouds: use the cloud-specific cognitiveservices audience Expected: Requests authenticate. Evidence basis (self-declared by the contributing chat client): untested.
