How to Change mask ACL in Azure Data Lake using Power Shell




I am trying to understand what is Mask ACL and use of it, We are currently managing ACL with Azure AD groups.


I have requirement to change Mask ACL for parent and sub folders including files, We have option to apply ACL in Azure Portal but it is very slow when we apply from portal. I am looking for power shell command where we can apply mask ACL to parent and sub/folders with files.


I have tried below power shell command but it's not working.


Set-AzDataLakeStoreItemAclEntry -AccountName 'xxxxxx' -Path 'xxxx' -AceType 'mask' -Permissions 'ALL' -Recurse -Concurrency 128 -ShowProgress


Below is mask ACL.
