samba - Nov 2006 - chdir (/export/share) failed, Access is denied, just went into production!!

This file server was working fine in testing, authenticating against
Active Directory no problem.  Just last night I put out a script to
switch users from our old Windows 2000 file server to this samba server
and a lot of people are getting "Access is Denied" errors when
connecting to the share.

Here is the samba log for one of the machines that get access is denied:

-----------------------------
[2006/11/20 08:32:00, 1] param/params.c:Parameter(383)
  params.c:Parameter() - Ignoring badly formed line in configuration

-----------------------------

And then that last error seems to appear every time a connection is
attempted.  I'm stumped and need help!!
