You can set up your linux box to import users via LDAP.  You will need to
make some changes to your AD schema, such as adding attributes for UniqueID,
mounts (typcially vfs, vfsopts, and vfsdir).  I have had problems getting a
clean group management system working, but the best work around I could
figure out is by adding MemberUID, userlist, and gid attributes to the AD
schema as well.  Unfortunately, this means adding users on the PDC to a
particular group does not add them on the Unix side, instead you have to
manually go in on the windows box using ADSI Edit, (or from the client side
using Domain admin privileges and cli tools) and manually add in the gid's
to each user name.  It's a pain, but it works.  There seems to be a serious
dearth of information on this.  Once you have LDAP authentication up and
running, then you can easily set up SMB pass through authentication with no
need for winbindd, though I've had some problems using secure passwords on

Hope this helps,
