samba - Jun 2013 - Losing Permissions of Files

Hi,

I have a OpenSuse 12.2 system running Samba 4.0.6 (compiled from source).
Every once in a while, we run into an issue where all permissions on a file
are lost. I've checked the ACLs, and they seem fine. The only way to get
permissions back is to copy the file to a new name, remove the old file,
and rename the file back to the original name.

Can anyone help solve this issue?

My smb.conf follows:
# Global parameters
[global]
        workgroup = XXXXX
        realm = XXXXX
        netbios name = XXXXX
        server role = active directory domain controller
        dns forwarder = 555.555.555.555
        dns forwarder = 555.555.555.666

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/XXXXX/scripts
        read only = No
        browseable = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No
        browseable = No

## Samba shares
[data]
        comment = General Company data
        path = /STR/corp/data
        read only = No

[projects]
        comment = Projects
        path = /STR/corp/projects
        read only = No

thanks,
Tanveer

- What exactly do you mean by "all permissions on a file are lost"?

- Can you show the 'getfacl' output on such a file, before and after?

- If permissions getting lost, did someone edit the file?

- Does it happen only on a special kind of files?

- etc.

Please give some more information on the issue.

This could be the same problem I am experiencing. My users are editing some
excel files with office 2010. The files lock and lose permissions. The only
way to "fix" this is to move out the file and move it back in, so it
resets
the file permissions with administrator. This has probably something to do
with the oplocks. I am also experiencing the issue with samba 4.0.6 as a dc
on fedora 18 x64.
