[Samba] chattr +a <file>

[Marcus Schopen]

Hi,

I want to apanding write access to a file a samba share. Is something 
like "chattr +a <file>" for a file in samba share possible? If I set 
"chattr +a <file>" on a file, it's not possible e.g. to write with a 
"echo test >> \\server\share\file" to this file from the windows client. 
Is there something like "chattr +a" for the smb.conf.

Thanks
Marcus
