You are running a workgroup and if you attempt to connect to a samba
share, you will probably be asked who to connect as, at this point, you
can use a username & password of a user that samba knows and you should
be connected as the samba user. If you now try to change the ACL's of a
file on the share from windows and try to use a windows user that is
unknown to samba, this will fail because, to samba, it is an unknown user.
