I don't like Quickbooks. Quickbooks does not support anything but
Microsoft and even that means a phone call to worthless call center in
India.

I would never suggest that anyone use Samba/Linux to host Quickbooks
share unless they wanted to experience real heartburn.

That said, I don't generally advocate 'force user/group' configuration
on samba shares either unless there absolutely were no other way.

I think Joseph is onto most of it with...

     chown root:DOMAIN\AD_Group /mnt/Intuit_Data/
     chmod 2770 /mnt/Intuit_Data/

and I would add one more thing to the share definition...

     store dos attributes = yes
     inherit permissions = yes

Which generally makes for happy workgroups on Samba if the share is mounted with user_acl which is generally the default for Red Hat/CentOS systems but I can't vouch for Quickbooks behavior.
