My guess is that you've got "wide links = no" set in your smb.conf ?
If so, Samba now uses realpath() to ensure the targetted path is inside
the exported share directory tree. I'm guessing that the implementation
of realpath() on your system is doing userspace lookups.

Try removing the "wide links" parameter and see if that fixes the problem.
