Hi Max,
I have experienced something similar. First I considered this to be a
bug, but as it seems it was a wrong approach.
As I am relatively new to Samba also, please do not consider this to be
a perfect solution.
It just works ;):
* In the Samba config and in local UNIX right management (chmod)
give free access to all folders.
* I transformed all UNIX users to Samba users (including AD
users+groups)
* Make sure you have ACL installed.
* Then, modify the access rights for your shares via ACL regarding
to your AD groups and users.
* I configured it with the ACL module in Webmin - it's quite
comfortable.
You might consider broaden the idmap to fit to the imported user IDs
from AD:
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
Here is my complete smb.conf:

Here is one my Threads I posted in Ubuntuforums. It should make no
difference if you are using Centos:
