[Samba] Deletion of directory symlink via Samba deletes files in original subdirectory on Unix

[Kathy]

I just confirmed that this problem exists on all our Samba servers,
irregardless of version. Here is an example of how I'm testing it:

On Unix SERVER I have a directory called /testdir/kathytest and inside
of kathytest are file1, file2, and file3  Testdir is a Samba exported
directory on SERVER.

I create a soft link in /testdir to point to kathytest:  ln -s
./kathytest ./testlink

So now if I go to /testdir/testlink it will take me to
/testdir/kathytest and I'll see file1, file2, and file3.

Now, in Samba I go to  \\SERVER\testdir and I see both the softlink
testlink and my directory kathytest.

Through Samba I delete \\SERVER\testdir\testlink.  It then asks me
from the Windows side "Are you sure you want to remove the folder
`testlink' and all its contents?".

I say yes and it deleted the "testlink" symlink and deletes file1,
file2, and file3 inside of kathytest.  The subdir kathytest does not
get deleted, however.

This happens on both ext3 and zfs exported filesystems, so it's not
just limited to ZFS.
