    • ONTAP replies with GetInfo Response of NT Status: STATUS_LOGON_FAILURE (0xc000006d)
  • The effective security style of the object is Unix, so it has a Unix ACL

::*> vserver security file-directory show -vserver roshar -path /alethkar/.snapshot -fields effective-style

  • The is-unix-nt-acl-enabled option is set to false

::*> cifs options show -vserver roshar -fields is-unix-nt-acl-enabled
