[Samba] Giving AD group members access to Samba server

[Joshua Penix]

Here's my situation, hoping that some of you who are running Samba in  
an AD environment will have insight:

Samba is acting as a member file server in an AD domain. In addition  
to the domain containing Samba, there are two other domains in the AD  
forest. All three domains have full trust between them. Each domain  
has a Global Security Group called ACAD_ENGR. Samba (through winbind)  
sees them as DOM1+ACAD_ENGR, DOM2+ACAD_ENGR, and DOM3+ACAD_ENGR. I'd  
like members from all three groups to have write access to a  
particular directory. This needs to be done with filesystem  
permissions, not share permissions, because underneath each directory  
there are further subdirectories that have varying access rights  
matched to other groups in the three domains.

Thoughts? Is this possible with Samba?
