  • ONTAP 9 
  • Snapmirror

Answer

  • It is expected behavior.
  • All information of the Snapmirror destination volumes are synchronized through snapmirror transer, including the ACL information in the file, which should be consistent with that on the source volume.
  • If using XDP snapmirror relationship, not SVMDR, that is, the configurations in the source SVM root volume cannot be synchronized to the destination cluster.
    • CIFS local user
    • CIFS loca group
  • The SID of the administrator user in destination SVM is different from that of the user in source SVM, so it is displayed as: source adiministrator's SID or win-name.
Example:
Demo_DES::*> vserver services access-check authentication translate -node Demo_Des-01 -vserver naafstest -win-name NAAFSTEST\Administrator
S-1-5-21-1859220071-2216865930-2624919371

Demo_SRC::*> vserver services access-check authentication translate -node Demo_SRC-01 -vserver naana006 -win-name NAANA006\Administrator
S-1-5-21-1738220992-1147683932-2156450179-500
 

Additional Information

  • NTFS ACLs are tied to SIDs, not windows users name or groups name.
  • Even if a local user or group with the same name is configured, it will not be accessible if the SID is different.
