How to use keyless auth (managed identity) for AzureOpenAIVectorizerParameters in integrated vectorization notebook?

[Pavan-Microsoft]

Hi team,

I'm trying to use the notebook at:

azure-search-integrated-vectorization-sample.ipynb

In the vector search configuration section, the AzureOpenAIVectorizerParameters currently requires an api_key:

# Configure the vector search configuration vector_search = VectorSearch( algorithms=[ HnswAlgorithmConfiguration(name="myHnsw"), ], profiles=[ VectorSearchProfile( name="myHnswProfile", algorithm_configuration_name="myHnsw", vectorizer_name="myOpenAI", ) ], vectorizers=[ AzureOpenAIVectorizer( vectorizer_name="myOpenAI", kind="azureOpenAI", parameters=AzureOpenAIVectorizerParameters( resource_url=azure_openai_endpoint, deployment_name=azure_openai_embedding_deployment, model_name=azure_openai_model_name, api_key=azure_openai_key, ), ), ], )

Is there currently a way to use keyless authentication (e.g., system-assigned managed identity) instead of providing an api_key in AzureOpenAIVectorizerParameters?

If not:
Is this a planned feature?
Is there a recommended workaround for now?

Hi, do you find any solution? I have the same question about this.
