samba - Sep 2012 - GUI file permissions problem

Hello,

If I login into a windows box and navigate to a file stored on a samba 
server, I can alter the file permissions by right clicking on the file 
and selecting 'properties' then 'Security'.

But if I login into a Linux box (running Ubuntu 12.04 & Samba 3.6.3) and 
navigate to the same file on the server, then right click on the file 
and select 'Properties' then 'Permissions', I get 'The
permissions of
"<filename>" could not be determined'.

This happens however I connect to the server, I have tried Nautilus, 
Caja, Eiciel and Gigolo. None of them can display the permissions of a 
file or a directory on a samba server. Is this a general Linux problem, 
or, as I am beginning to think, a problem with the way that one samba 
server connects to another i.e. in a totally different way from windows.

Is there anyway that I can set the ACLs on the Samba server from another 
Linux box without resorting to SSH & setfacl?

Rowland

Using Nautilus "connect to server" I think uses libsmbclient,
which doesn't export ACLs. You need to mount using the
cifsfs kernel module, which should allow direct modification
of the POSIX ACLs if the Samba server has "unix extensions = yes"
set.
