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:

[Samba] Problem with Centos 5.3 + Samba 3.0.33 +AD (2k3)

Hi everyone,
I have an issue with Samba agains Active Directory.
The authentication works just fine but when it comes to shares I've ran into
some problems.
If I use any group mapping from the AD it won't let me access it so I figure
that is where the problem lays.
If I comment out "valid users", "force user" and "force group" then I have
no problems and it goes by the file system restrictions.
Does anyone ever run into the same problem?, is there a way to fix it?
Thanks in advanced.
Here is my smb.conf:
[global]
netbios name = filer
workgroup = MYCOMPANY

Here is the error from the workstation that is trying to get access to the
server.
The user is part of the Group PM.

Hi,
for the last two weeks ive been trying, to authenticate against a
samba-domain using a win2k3-server. the server joined the domain without
any problem and the basic login seems to work. but if i try to execute
programs from mapped network drive (mapped using a domain-logon-skript),
it fails with a message telling me, that i dont have sufficient rights
to do so.
the share has a forced user and group like this;
...
[programm]
comment = samba
guest ok = yes
path = /samba
public = yes
browseable = yes
writable = yes
force user = samba
force group = users
...
this only happens on the win2k3-server, all xp-workstations work just
fine with domain-logons, network-drives, logon-skripts, etc. in the
samba-logs for the win2k3-server i found this:
...
[2009/05/22 09:20:51, 3] auth/auth.c:check_ntlm_password(219)
check_ntlm_password: Checking password for unmapped user
[]...@[srv_name] with the new password interface
...
compared to logons from an xp-workstation its missing the user/domain
part that should look like this:
...
[2009/05/22 09:15:45, 3] auth/auth.c:check_ntlm_password(219)
check_ntlm_password: Checking password for unmapped user
[workgroup]\[kapp...@[buchhaltung] with the new password interface
...
does anyone have an idea what seems to be the problem with win2k3?
mabye its a switch i have to (de)activate on the win2k3-side?
regards
volker
Mit freundlichen Grüßen
