The good news is I believe I've found the problem:

RUNNING:

# file: samba/private
# owner: root
# group: root
user::rwx
group::r-x
group:bind:r-x
mask::r-x
other::---

RESTORE:

# file: samba/private
# owner: root
# group: root
user::rwx
group::r-x
other::---

The bad news is everything under sysvol has the same problem.
So I have over a hundred of permissions discrepancies to manually 
reconcile before I can attempt another roll back :(
And, moving forward, I need to modify Bacula backup parameters.
