It is.  I realized belatedly, that 3da9e136.acl is apparently a
directory, not a file.  So I tweaked my local test accordingly, and
here's my session output:

  $ mkdir acltest
  $ chown Administrators.SYSTEM acltest
  $ cat aclfile.sav
  acltest
  D:P(A;OICI;FA;;;SY)(A;OICI;0x1200a9;;;WD)(A;OICI;FA;;;BA)
  $ icacls . /restore aclfile.sav
  processed file: .\acltest
  Successfully processed 1 files; Failed processing 0 files
  $ icacls acltest
  acltest NT AUTHORITY\SYSTEM:(OI)(CI)(F)
          Everyone:(OI)(CI)(RX)
          BUILTIN\Administrators:(OI)(CI)(F)

  Successfully processed 1 files; Failed processing 0 files

So the DACL is now identical to yours.  Let's try getfacl:

  $ getfacl --version | head -1
  getfacl (cygwin) 3.3.3
  $ getfacl acltest
  # file: acltest
  # owner: Administrators
  # group: SYSTEM
  user::rwx
  group::rwx
  other::r-x
  default:user::rwx
  default:group::rwx
  default:group:SYSTEM:rwx
  default:mask::rwx
  default:other::r-x

Ok, that looks correct.  Now compare with the output of your getfacl:

>   #getfacl 3da9e136.rbf
>   # file: 3da9e136.rbf
>   # owner: Administrators

>   user::rwx
>   group::rwx
>   group:SYSTEM:rwx
>   mask::rwx
>   other::r-x

It's exactly the same as the one my gefacl prints above, except the
"default:" specifier for default ACEs is missing in the output.

I can't explain that, sorry.  Old getfacl version?  Running an output
filter of some sort?  Clutching at straws here....

By default I'm using "list-reply-to" in mutt, so replies are only
going to the mailing list.  I added you to the CC for this reply.

It did, thanks.
