Still pulling my hair out over this. We moved from 'smbfs' to 'cifs' (/bin/mount -t cifs --verbose -o username=backup,password=OMITTED "//ables-dt/Documents" /backup) with identical results. I've thrown together an example session with smbclient and a debug-10 logfile: http://www.divus.org/?id=306 Some files are readable, others are not, despite the 'backup' user having been granted SeBackupPrivilege: [root@matrix samba]# net rpc rights list accounts ... Everyone No privileges assigned PPSbackup SeBackupPrivilege (For those just tuning in, 'matrix' is a Samba 3.0.21a PDC on a Windows domain, with an openldap/smbldaptools backed. Everything else is working just fine, but, when matrix goes to mount Windows XP workstations' shares to do nightly backups, it's getting permissions problems accessing some but not all files, despite the fact that, to my understanding, SeBackupPrivilege is supposed to supercede all other considerations.) Help?! How would/could/did you implement a reliable Windows->Linux backup scheme? Thanks, Chris
