Hi all, I'd like to know that whether it is possible to map domain user to Everyone and preserve ACL information when "xcopy /O /K" files from window client to samba. Both samba server and windows client have joined Active Directory. It seems that username map won't work since Everyone is a special group rather than user in the domain. eg: Source: Windows 2k3 test.txt ACL: Owner: Domain\user A Full Access Destination: Samba server test.txt ACL: Owner: Everyone Full Access Any clue is welcome. Best Regards nelson
