samba - Jan 2009 - SMB Signing issues... smbclient works, mount does not...

Greetings Samba peoples... apologies for the long post.

I have an issue that remains unresolved on my usual forum, linuxforums.org... it
relates to SMB Signing when connecting from Linux to a Win 2003 file server.

My OS:
>> PClinuxOS - a Mandriva derivative
My Samba versions:
>> samba-client-3.0.30-3pclos2007.i586.rpm
>> samba-common-3.0.30-3pclos2007.i586.rpm
>> samba-doc-3.0.30-3pclos2007.i586.rpm
>> samba-server-3.0.30-3pclos2007.i586.rpm
When attempting to mount a remote share, "mount -t smbfs //server/share
/mnt/dir -o username=user,password=pass" I get the following error:

<snip>
cli_negprot: SMB signing is mandatory and we have disabled it.
14216: protocol negotiation failed
SMB connection failed
<snip>

When I try smbclient... "smbclient //server/share -U user" and enter
my password, smbclient connects without issue.

I have tried to solve things, but have come across a void in the help files, man
files and online postings with regards to SMB Signing. LOL I was especially
mystified to learn from a posting on your mail-list that there is an
undocumented smbclient switch ("-S", i.e. capital "S") which
can be used to enabled or disable SMB signing at the command-line. Why is this
switch not in any of the man files???

Anyway, using "smbclient //server/share -U user -S off" results in the
exact same error message quoted above, as you would expect. If I use "-S
on" however, smbclient connects properly.

In an effort to get the mount command to work, I have assumed that smb.conf is
the reference that mount.smbfs uses. I have tried all the various combinations
of "server signing = <x>" and "client signing =
<x>" (where <x> is either Auto, Mandatory or Disabled as per
the man file and other refs for smb.conf). I have even tried "on" and
"off". Nothing works... mount, via mount.smbfs, always gives the SMB
Signing error. It's like it isn't reading the config file.

Any help on this issue would be appreciated, especially info on what variables
mount.smbfs reads and what the -S hidden switch really does.

Also, please note that I am aware of cifs... using cifs in the mount command
also fails, with:

<snip>
mount error 13 = Permission denied
Refer to the mount.cifs manual page (e.g.man mount.cifs)
<snip>

Which the /var/log/messages (and dedug etc.) file tells you is because of SMB
Signing failures... didn't note the exact error down, but was something
about an unexpected SMB signature.

I am hoping that since smbclient works I should be able to get mount via smbfs
to work too.

Thanks.

smbfs has been deprecated quite a while ago. Please try using cifs.
