[Samba] Group membership not being honored

[Eric Diven]

I've got a relatively simple permissions scheme I need to implement, and
I'm having issues with group membership.

I have a share that I need to grant an active directory group full
control to.  If I add an AD user to the ACL on the directory that is the
root of the share, the user can access it.  If I add an AD group to the
ACL on that same directory, group members cannot access the directory.

Any ideas please?

Thanks,
