Customer is trying to Reacl a NAS ECM eNAS 8.1 Upon attempting an actual re-acl we are failing with the following two errors
"SetKernelObjectSecurity: The securityID structure is invalid"
"SetKernelObjectSecurity: This security ID may not be assigned as the owner of this object"
PowerMax might not recognize the Windows SID that we are trying to assign as the owner because it uses its own internal system.
PowerMax uses a UNIX-based file system (or a similar system) which has its own model for managing user and group ownership, distinct from Windows.
In this case, Customer need to change the settings using command line in EMC eNas
1. This controls how the system behaves when there's an error mapping a Windows Access Control Entry (ACE) to a UNIX user/group during ACL processing.
server_param server_2 -facility cifs -modify acl.mappingErrorAction -value 3
2. Controls how the system behaves when restoring security descriptors (SDs), like during file copy/restore, and an error occurs.
server_param server_2 -facility cifs -modify acl.FailOnSDRestoreError -value 0
