Mounting error after upgrading to wheezy - Changes in mount.cifs from 4.5 to 5.5?

Mounting error after upgrading to wheezy - Changes in mount.cifs from 4.5 to 5.5?

[Philipp Flesch]

Hi from Munich,
we have some special issues with the current cifs-utils (5.5) in 
Debian Wheezy.

A lot of our (raw) logfiles are stored on a Windows 2008 R2 
fileserver, while we use Debian to generate the reports.

The share is available as
\\fs01\Share

while the logfiles can be found in special subdirs
DepartmentA\Stats

We use a seperate user "stats_user" to access the files. This user has 
no "listing-rights“ above the final "\Stats" directory.

Using Windows 7, everything works fine...
\\fs01\Share\DepartmentA\Stats can be directly mounted to an local 
drive...

Using cifs-utils (4.5) in Squeeze everything works fine, too!
mount -t cifs //fs01/Share/DepartmentA/stats /mnt/DepartmentA_stats -o 
user=stats_user,domain=xy,password='xyz'
makes all files accessible from Debian.

Using the same mount-command with the same user, we got a "permission 
denied".
Retrying with a default-user (with listing-rights) the subdirectory is 
mounted without any errors...

Are there any big changes between 4.5 and 5.5 which can cause this 
error? Is there a solution, to avoid the issue?

Thank you very much

Philipp

More likely, a change to the kernel and not cifs-utils is causing this
for you. What kernels do your working and non-working configs have?
Does it work if you mount with sec=ntlm ?

I doubt that the sec=ntlm would make much of a difference but would be
interesting to see what the access denied is coming back on - since
from what you describe listing the contents of the root directory of
the share should be permitted to both users so this is not an access
denied on top of prefixpath issue as we had seen a few years ago.

(working) squeeze --> 2.6.32-5-686-bigmem
(non-working) wheezy --> 3.2.0-4-686-pae

Sorry, but perhaps I described the share-configuration not exact enough.
listing the contents is only allowed in the final (second) subdirectory, 
but not in the root of the share and not in the first subdirectory:

no    listing allowed        \\fs01\Share
no    listing allowed         \\fs01\Share\DepartmentA
         listing allowed         \\fs01\Share\DepartmentA\Stats

Greetings

   hi,
   I just see this mail now, coming back home...
   I had a similar problem when kernel change from 3.2 to 3.10.
   and found that the 3 following commands work:

      mount -t cifs -o sec=none //wehd/hdd /d6
      mount -t cifs -o "guest,sec=ntlm" //wehd/hdd /d6
      mount -t cifs -o "guest,sec=ntlmv2" //wehd/hdd /d6

best regards,
