[Samba] Question about mount.cifs and smbclient

[Marton Neher]

Hi!

I have a problem for a few weeks, and can't figure out what could be the
problem.
The client computer runs RHEL 5.2 (arch: x64_64); the smb server is
unknown for us.
I'm sorry, that I can't provide any info (usernames, servernames, IPs,
etc), they are masked to look like variables. But they are correct as
far as i am concerned.

When I try to mount it with mount.cifs (.smbfs doesn't exist on RHEL) I
get the following error:

# mount /$SERVER/vobstg/
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

After reading debug messages I found:

# dmesg

 CIFS VFS: cifs_mount failed w/return code = -13

The entry in fstab is the following:

//$SERVER.FQDN/vobstg    /$SERVER/vobstg    cifs   
rw,netbiosname=$NETBIOSNAME,credentials=/etc/samba/$USER.credentials,domain=$DOMAIN,uid=$LOCALUSER,gid=$LOCALGID,file_mode=0660,dir_mode=0770,auto
0 0

It gives me NT_STATUS_INVALID_WORKSTATION error. The user has a field in
ActiveDirectory: `userWorkstations: $NETBIOSNAME1,$NETBIOSNAME2'. The
RHEL5.3 machine is joined to the doimain with `net ads join'. The
machine's netbiosname is $NETBIOSNAME2.

The interesting thing is that smbclient can connect to the host:

# smbclient -W $DOMAIN -U $USER \\\\$SERVER\\vobstg $PASSWORD
Domain=[$DOMAIN] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager]
smb: \> ls
  mvfs.zip                            A   129564  Wed Nov 10 16:38:35 2004
  quickie.iso                         A 18231296  Tue Mar  8 13:28:59 2005
  mvfs.o                              A   361193  Thu Nov  4 12:09:00 2004
(...)

I have tried smbclient with an another user (which doesn't have the
$NETBIOSNAME2 [the computer's name] in UserWorkstation field in
ActiveDirectory):

# smbclient -W NSN-INTRA -U ntmsci \\\\bulinap01\\vobstg NSNintra45\&\&
session setup failed: NT_STATUS_INVALID_WORKSTATION

This seems to be correct.

My question is that why can't i cifsmount the share while i can access
it through smbclient?
What is the difference?
What can I do now?

Hoping that you can help me (our IT service desk won't),
