samba - Jan 2006 - macosx (mount_smbfs ok - macosx GUI not working)

Hi there,

I have machine running:

Linux 2.2.20
Samba version 3.0.14a (debian package)
Check the end of the email for the samba config file

The samba machine is sharing a directory and it is validating users
through a windows 2k PDC.

Everything works if I use windows/linux clients, but when I try to
use a share directory from a macosx client (10.4.4) using the
finder (GUI), it doesn't work. I can mount the resource, and I can
create directories, but when I try to copy stuff on those directories
it complains telling me that I don't have enough permissions.

The weird thing is that, if I try to mount the share from the console
using mount_smbfs(8), then it works perfectly. I have even try it to
mount the share in this way and then to launch the finder in the
directory where I mounted the share, but if I use the guy to copy
stuff I get errors, if I use the command line, it works.

I checked the logs but I haven't found anything interesting, plus
the debug level is pretty low and I can not change it because there
is people using the system.

In addition to that, I have tried exactly the same config file in
another machine which is running:

Linux milhouse 2.6.13
samba 3.0.14a (compiled from source)

and it works fine, using linux windows or macosx as clients. 
                                                           
The next thing I am going to try is to compile samba 3.0.14a on
devlinux (production samba machine) using exactly the same compilation
directives and see if it works.
                                          
I would appreciate any help you can give me.

Thanks,
