Did you enable the DNS lookup during compile?  If so then you can get
rid of the [realms] section below.
Unfortunately, no.  So I'll have to keep the realms section below I 
guess.

How are the users/groups laid out in AD?
Well, that problem seems to have gone away - I reboot the machine and 
see all my domain users in the KDM loginwindow.  wbinfo -u confirms 
this.

Have you setup pam_winbind.so ?
I have it copied to /lib/security/ where all the pam modules are.  Is 
there more to setting it up than that?

See pam_mount.so and smbfs (or patches for the newer cifsvfs).
Thanks, I'll look that up.
