Terraform Configuration Files

terraform {
  backend "azurerm" {
    resource_group_name  = "StorageAccount-ResourceGroup"
    storage_account_name = "abcd1234"

Crash Output

Expected Behavior

terraform should have used the access token from the az login to authenticate to the remote backend.

Actual Behavior

Error: Error building ARM Config: Error populating Client ID from the Azure CLI: No Authorization Tokens were found - please ensure the Azure CLI is installed and then log-in with 'az login'.

Steps to Reproduce

$ export AZURE_CONFIG_DIR=[not $HOME/.azure]
$ az login
