SMB is really complex, and Samba adds to the complexity.

If the remote drive is a Windows share, check if the server shares the
folder with "Full Control" for everyone.

If the server is a Samba share, check if `force unknown acl user = yes'
and for the share itself, check that

  read only = No
  vfs objects = acl_xattr
  map acl inherit = Yes
  store dos attributes = Yes

Not sure if that helps, but I don't have any other idea.  I'm running
Samba in an AD environment and "it works for me" :-P
