Dear all,
I have a problem mounting a Windows 2012 R2 share with any newer version
of cifs.
I discovered that it works with version 1.61 (Ubuntu 10.04) but does not
on 2.02, 2.06 and 2.07.
The error I get is "Permission denied".
This is the content of /proc/fs/cifs/DebugData on the old machine where
mounting works:

Below is a log I captured some time ago with an older kernel but the
symptoms are completely unchanged:
