Currently Redpanda connect does not provide configuration parameters for Azure Blob Storage input/output to configure Managed Identity or Service Principal but expects this configuration to be provided by environment variables. This limits the pipeline to use a single Managed Identity or Service Principal for all Azure Blob Storage inputs and outputs and does not allow use cases where the input has to use Service Principal, and the output has to use Managed Identity or to use more than one Managed Identity or Service Principal in a single pipeline.
