authorizationfailure on ls fs on mount point files

[rmubeenhsal]

One of our users has as of last week started seeing an authorization failure when he tries to list the files in the Azure storage account using Databricks Cli or Databricks API(using Python). He can list files on the Databricks portal or through the execution of notebooks. Not when he executes unit tests on his local machine. Has anything changed on Databricks last week? We activated the preview version of our account last week. Also, this works if the storage account networking is set to public access.

Have you checked the list of allowed ip addresses that are set for the Storage account in Azure? Is user using VPN or internal network, we might need to confirm if the network where the user is trying to list is set as allowed.

We have added IP address of local machine to the firewall on the storage account. That did not help. We are off our vpn. The databricks is outside our firewall.
