Add support for Azure RBAC authorization to Azure AI Search - currently only API key is supported

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

Currently the only langchain way of authorization to Azure AI Search is through API key (https://python.langchain.com/docs/integrations/vectorstores/azuresearch#configure-vector-store-settings). In Azure it's way more robust to provide access through RBAC mechanisms, so that one can easily provide and revoke access to identities. Therefore I'd like langchain to support authorization using JWT tokens, similarly as with Azure OpenAI resources.

Motivation

In Azure it's way more robust to provide access through RBAC mechanisms, so that one can easily provide and revoke access to identities.

Proposal (If applicable)

Something similar to https://python.langchain.com/docs/integrations/llms/azure_openai#azure-active-directory-authentication

The latest version fully supports RBAC, but only for public cloud, not for other national cloud.

Can you provide any information on how this is supported?

@green999 Please provide an example.
As I see azure_search_key is required parameter.

Adding support for this one - enterprise environments will often disable key-based authentication as it's seen as generally insecure.

Managed Identities are the only way we are allowed to connect to azure resources in many cases.
