I know im a little late to the discussion but this maybe of some help. I used this howto
found at http://xciprox.googlepages.com/winbind.pdf but I can't remember where i found it, but kudos to the person that wrote it. It is debian based but im guessing can it be applied to redhat equivalent values.You actually have to configure a number of things, primarily pam to allow active directory logons. Then as Dan stated add the "user+ADGROUP" values to each share in smb.conf.

it's my understanding that with winbind you have the capability in the
smb.conf to set allows for an AD group, or a certain user in the AD
group.

i.e. user+ADGROUP

I wrote a document on this for my previous job but I need to dig it
up.. that is, unless someone else wants to elaborate :)
