[Samba] SeBackupPrivilege

[samba at divus.org]

We're using Samba 3.0.21a-1 on a CentOS 4.2 server (kernel 
2.6.9-22.0.2.ELsmp); everything works more or less fine, 
it's functioning as the PDC with an OpenLDAP back end (setup 
essentially straight from the Idealx.org playbook), etc.

We're trying to mount Windows shares to back them up, and 
getting "permission denied" errors when trying to read 
certain files from those shares.

A typical operation might look like this:

server:~# mount -t smbfs -o 
username="\\LCLDOMAIN\backup",password="password" 
//workstation/share /mnt/backup

server:~# tar jcvf /mnt/backup_drive/workstation.tar.bz2 
/mnt/backup

The backup user has the SeBackupPrivilege right set, which 
to my understanding should allow it read-access to every 
file on those shares...?

server:~# net rpc rights list backup
Password:
SeBackupPrivilege

I'd love to know what I'm doing wrong.  Haven't really 
touched Samba since 2.0 was in Beta, so to say I'm slightly 
in over my head might be an understatement...

Thanks!
