samba - Mar 2011 - CIFS mount with non-ascii (UTF8) password is not working

Hi , 

I have French CIFS server. 

If I try to map a share from any windows machine with non-ascii (UTF-8, french
characters are part of password) password, it is successful.

But If I try from linux machine, it fails. 

mount -t cifs //MACHINE/DatasetFIGS_?????????????  /tmp/rahul -o
user=??,password=??,domain=eKKDr
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
 

Does CIFS supports non-ascii password?

Maybe it's not only a problem with the password; the path seems to be  
non-ASCII too.

And non-ASCII has many representations - not only UTF-8.

Viele Gruesse!

I am able to mount same path when password is in ascii.

But it gives problem when it is non-ascii.

can you please try by using the cifs mount option
  iocharset=utf8

Cheers, G?nter

On the Linux machine, what output does the "locale" command give you?

If you type the password at the Linux prompt where you can see it, do you get
the right characters?  If the keyboard isn't set right in Linux, it
won't work.  To see exactly how the password is being encoded, use
"echo <password> | xxd" (although obviously don't post the
output for a real password here).

Was the password set from Windows or from Linux?  If from Windows, then I would
expect the encoding to be in either UTF-16 or the Windows locale 8-bit encoding,
not UTF-8.  For example, "Latin Small Letter E With Acute" is encoded
as 0xE9 in the Windows Western encoding, 0xE900 in UTF-16, and 0xC3A9 in UTF-8.

Does it work any better if you use Samba's own mount.cifs program directly
rather than going through mount?

I do not know what (if any) character encoding translation the cifs module does.
Check whether the locale and "testparm -vs | grep char" on your CIFS
server match the settings on the Linux machine you are doing the mapping from.

Are you able to use smbclient command successfully on this very same machine?
If you can, I guess we can consider this as a bug in cifs client?

This is a windows share.  But I am trying to mount it from Linux. 

I tried iocharset=utf8 option, but it didn't work. 

If I map the same share from laptop (Windows OS), it work fine. 

I enabled CIFS debugging. Following are errors: 
=============================================================kernel: Status code
returned 0xc000006d NT_STATUS_LOGON_FAILURE
 
!!Mapping smb error code 5 to POSIX err -13 !!
 nt_status is c000006d
=============================================================
I am using username : ?????rkkk  and password ?????rkkk. And user
?????rkkk is in Administrators group.
