No.  Since you're not using AD accounts and no winbind, the ACL returned
by Samba reflect the UNIX user and UNIX group the file is owned by.
I don't think there's a reliable way to convert the SIDs in the ACL to
the current user and primary group, except for another mount flag.

It's safe, usually.
