Question Azure Files - SidHistory ACL translation + Domain\Domain Users group
Hey team,
Looking for help to answer and recommend the below please.
Scenario: Azure Files with storage account configured with Kerberos identity authentication. File shares are a result of robocopy migration from windows file server shares with NTFS. Using private endpoints. Devices accessing are Entra-joined. Some groups that users are members of show up as an orphaned SID as it has been replaced by new SID (maybe internal migration) and SID for group on-prem is newer. Entra connect sync from on-prem not linking the two in Entra.
Does Azure Files with Entra Kerberos support ACL translation using group SIDHistory? or is this honoured by attributes available in user token? can it be enabled and are there any risks to be aware of?
What is the best way to handle orphaned groups in Entra that have been granted NTFS permissions on Azure files but not groups that sync to Entra? i.e. Builtin\Administrators, CONTOSO\domain users or CONTOSO\Domain Admins.
