Hello Sebastian and Hongwei,
Sorry for being silent on this.
So if I try to sum up we agreed that:
* in order to allow modification of ACL on files sdeffectiverights must
have the flag DACL_SECURITY_INFORMATION set, and the ACL must have the
SE_DACL_PROTECTED set in the control flags.
* in order to avoid a warning message ACL of Policy object must be
synchronized with ACL in the files following this logic for the translation:
The specific rights in access mask for Active Directory object
are defined in 5.1.3.2 of MS-ADTS as follows.
#define RIGHT_DS_CREATE_CHILD 0x00000001
#define RIGHT_DS_DELETE_CHILD 0x00000002
#define RIGHT_DS_LIST_CONTENTS 0x00000004
#define ACTRL_DS_SELF 0x00000008
#define RIGHT_DS_READ_PROPERTY 0x00000010
#define RIGHT_DS_WRITE_PROPERTY 0x00000020
#define RIGHT_DS_DELETE_TREE 0x00000040
#define RIGHT_DS_LIST_OBJECT 0x00000080
#define RIGHT_DS_CONTROL_ACCESS 0x00000100
The specific rights in access mask for a file or directory object
are defined as
(http://msdn.microsoft.com/en-us/library/aa364399(VS.85).aspx )
#define FILE_READ_DATA ( 0x0001 )
#define FILE_LIST_DIRECTORY ( 0x0001 )
#define FILE_WRITE_DATA ( 0x0002 )
#define FILE_ADD_FILE ( 0x0002 )
#define FILE_APPEND_DATA ( 0x0004 )
#define FILE_ADD_SUBDIRECTORY ( 0x0004 )
#define FILE_CREATE_PIPE_INSTANCE ( 0x0004 )
#define FILE_READ_EA ( 0x0008 )
#define FILE_WRITE_EA ( 0x0010 )
#define FILE_EXECUTE ( 0x0020 )
#define FILE_TRAVERSE ( 0x0020 )
#define FILE_DELETE_CHILD ( 0x0040 )
#define FILE_READ_ATTRIBUTES ( 0x0080 )
#define FILE_WRITE_ATTRIBUTES ( 0x0100 )
The generic access rights that are common to all objects are
#define DELETE (0x00010000L)
#define READ_CONTROL (0x00020000L)
#define WRITE_DAC (0x00040000L)
#define WRITE_OWNER (0x00080000L)
#define SYNCHRONIZE (0x00100000L)
#define STANDARD_RIGHTS_ALL (0x001F0000L)
The following logic is used by GPMC to convert a access mask for
DS object to a access mask for SYSVOL.
DSAccessMask as Input;
SYSVOLAccessMask as Output;
SYSVOLAccessMask = DSAccessMask;
SYSVOLAccessMask&= STANDARD_RIGHTS_ALL ;
if ((DSAccessMask& RIGHT_DS_READ_PROPERTY) AND
(DSAccessMask& RIGHT_DS_LIST_CONTENTS))
SYSVOLAccessMask |= (SYNCHRONIZE | FILE_LIST_DIRECTORY |
FILE_READ_ATTRIBUTES | FILE_READ_EA |
FILE_READ_DATA | FILE_EXECUTE);
if (DSAccessMask& RIGHT_DS_WRITE_PROPERTY)
SYSVOLAccessMask |= (SYNCHRONIZE | FILE_WRITE_DATA |
FILE_APPEND_DATA | FILE_WRITE_EA |
FILE_WRITE_ATTRIBUTES | FILE_ADD_FILE |
FILE_ADD_SUBDIRECTORY);
if (DSAccessMask& RIGHT_DS_CREATE_CHILD)
SYSVOLAccessMask |= (FILE_ADD_SUBDIRECTORY |
FILE_ADD_FILE);
if (DSAccessMask& RIGHT_DS_DELETE_CHILD)
SYSVOLAccessMask |= FILE_DELETE_CHILD;
* All ACE for allowed object are wipped out when "translating" AD ACL to
File ACL
* For the following ACE OI and CI flags are always set in the resulting
file ACE:
ACCESS_ALLOWED_ACE_TYPE
ACCESS_DENIED_ACE_TYPE
SYSTEM_AUDIT_ACE_TYPE
Am I right ?
For the part that are "hardcoded" like this will it change any time soon
? Also do you plan to document this in any kind of document ? if so
which and when ?

Hi Matthieu,
With regards to ACCESS_ALLOWED_OBJECT_ACE, we do wipe it in the process. That's
hardcoded.
With regards to the RU...
I need further clarification on what you are actually seeing.
It is my understanding and that since prew2k clients will not download
policies, the ACEs will be cleared if they contain that well known SID.
We are still investigating but please let me know if that explains what you are
seeing.
Thanks!

Hi Matthieu,
With regards of the OI and CI flags, we always set those flags on if the ACE
type is any of the following 3 types:
ACCESS_ALLOWED_ACE_TYPE
ACCESS_DENIED_ACE_TYPE
SYSTEM_AUDIT_ACE_TYPE
This is hardcoded.
I'll provide you with the answer to your other question soon.

Hi Matthieu,
Just a clarification to ask you for:
We are discussing with Hongwei and the PGs if it is that you are seeing GPMC "expect"
the inheritance to happen OR if it is that you are dumping the ACLs and "seeing" the
flags always.
What I see if when I dump the SD of the files modified by GPMC after it realize
that there was a mismatch between the SD in AD and the SD in the Policy folder.
Note: it was with XP sp2 as a client.
Matthieu.
Please clarify because we were under the impression that we had to look into
the client tool, but if the latter is what your question means, then we need to
look into AD.

Hi Matthieu,
We are still actively working on this and I do have the PG engaged.
Please accept my apologies if we are delaying a little longer than expected. I
guess we can say that the holidays affected the timing a little without trying
to use that as an excuse.
I'll keep you posted as soon as I have news.

Hello sebastian
And last but not least question, it seems that GPMC whats to have OI and CI flags on every
ACL entries is it due to the presence of the "SDDL_AUTO_INHERITED">control in
the SDDL ?
Any news on this ?
More exactly my question is why this flag appear on each ACE ?
Also do you plan to document this in a WSPP document ?

Matthieu,
I double checked the logic and your assumption is right. The return
value for SYSVOL access mask should be assigned to the input value first. For
your other questions, since I am out of office , Sebastian will work on them
and let you know.
Thanks!

Hello Hongwei,
I've been working on the translation function, I am getting quite similar ACL
right now but I have some remarks and questions.
The pseudo code contains this:
DSAccessMask as Input;
SYSVOLAccessMask as Output;
SYSVOLAccessMask&= STANDARD_RIGHTS_ALL ;
I have impression that it should be
DSAccessMask as Input;
SYSVOLAccessMask as Output;
SYSVOLAccessMask = DSAccessMask;
SYSVOLAccessMask&= STANDARD_RIGHTS_ALL ;
Maybe the third line is implied in this kind of pseudo code.
Also it seems to me that GPMC is discarding any ACL of type
ACCESS_ALLOWED_OBJECT_ACE (OA) and also everything related to SID
SID_BUILTIN_PREW2K (RU).
And last but not least question, it seems that GPMC whats to have OI and CI flags on
every ACL entries is it due to the presence of the "SDDL_AUTO_INHERITED"
control in the SDDL ?
Thanks for your answers.

Matthieu,
Matthieu,
The attached GPMC log shows the problem of inconsistency
between ACLs of the policy object and that of SYSVOL folders. The
log shows that

The access mask for the ace of Active Directory policy object is 0xf00ff.
When the GPMO converts the access mask to a corresponding file system access
mask, it expects 0x1f01ff. For SYSVOL, you set the access mask to 0xf00ff.
They don't match and that is why inconsistency is declared. In the SYSVOL
access mask you set, you missed 0x100000(SYNCHRONIZE) and
0x100(FILE_WRITE_ATTRIBUTES).
Since AD objects and SYSVOL file/folder objects are different objects,
their specific rights in access mask are not one-to-one matched. The following
are the definitions of bits for both objects.
The specific rights in access mask for Active Directory object are
defined in 5.1.3.2 of MS-ADTS as follows.

Hi Hongwei,
For the moment it's quite clear why we fail as we do not set any

I will already fix this + the sDRightsEffective attribute and I'll
see if it do the job.
I worked a little bit on the ACL and still face "unsynchronized" ACL despite
the fact that now our Policy folder are created with the same ACL as in AD.
Let's take the following
policy:{7557D70F-14C9-4EA5-8369-10AE7C2C31D3}
I face the message that the ACL is unconsitent with the one stored

Which looks like the ACL that were present for the file.
I also made a tcpdump capture (attached to this mail) and it's clear that the
nTSecurityDescriptor is like the one just above. (packet 927).
So what's going on, with an ACL that is the same when stored in the AD,
transmitted through LDAP and stored in the file we have at the end GPMC that
change the value but it's hard to understand how it construct this ACL.
I attached also the GPMC log when I clicked on "OK" so that the ACL in AD and
ACL for the file are synchronized (well from GPMC point of view).
I will try to use also the same SSDL as in w2k3 to see if I have
the same resulting delagation or not.
For the moment I have some tests to do before going back to you.
Regards.
Matthieu.

Matthieu,
For Problem #1, only the SE_DACL_PROTECTED(0x1000) has to be set
for ControlFlag in Security Descriptor in order to pass the step 2
in consistency testing. This is translated to "P" flag in SDDL.
With this said, it is normal to have D:PAI since this will
indicate that the SE_DACL_PROTECTED bit is set. It seems that your
Security Descriptor is right in this regard. We have to get more
information to see why the consistency checking fails. Could you
enable GPMC logging as described in my previous mail? Please
enable VERBOSE for Gpmgmttracelevel.
Just for your reference, you can also use ldp.exe to display the
security descriptor of a policy object in SSDL string format and
parsed display format.
Thanks!

Subject: Re: Group Policy questions
Hello Hongwei,Matthieu,
Thank you for the answers. I have a few more questions:
After testing, I think that I have some information to help you
resolve all the problems.
Problem #1:
As described in the following link
(http://support.microsoft.com/default.aspx?scid=kb;en-us;828760 )
, GPMO will check the consistency between ACLs in GPO in Active
Directory and ACLs of policy folders in SYSVOL when a GPO object
is clicked in GPMC. The logic is something like the following:
1. Get the security descriptor (SD) for GOP in AD and folders in
SYSVOL
2. Check both security descriptors to make sure they are DACL
protected (PD bit in Control flag is set). If not, ACL
consistency check will fail.
3. For every permission in AD DACL, there should be the same
permission in SYSVOL DACL. If all permissions have be checked
through in AD ACL and there is still extra permission in SYSVOL
ACL, ACLs are not consistent.
Looking at the your attached SSDL of the new policy, it doesn't
have PD bit set. (D:PAI means DI bit is set, which is not DACL protected).
This will fail the second step of consistency checking.
I did an extraction of a W2K3 policy and got the following SDDL:
O:S-1-5-21-3208502064-746857408-2662927446-512G:S-1-5-21-320850206

And you say that we should not have AI flag (because it's related
to SE_DACL_AUTO_INHERITED aka DI bit) just the P flag (because
it's related to DE_DACL_PROTECTED aka PD bit) right ?
But the above SDDL seems to show the opposite, I can't exclude the
fact that we have bugs when reading ACL and/or when converting
them into SDDL but before to trying to check this I would like to
be sure of which flag we should see.
I even tweaked XCACLS.vbs (attached to this email) from
http://support.microsoft.com/default.aspx?scid=kb;en-us;828760 to
make it show the value of the control and it appear that the ACL
for the c:\windows\sysvol has both PD and DI bit sets
ie.
Directory: C:\WINDOWS\SYSVOL
ControlFlags: 37892
Do gpmc pass some controls while making its LDAP request because I
had a look at the delegated permission through GPMC and through
dsa.msc they are really different (a lot of inherited from parents objects).
Problem #2:
In GPMO, if the attribute sDRightsEffective of selected GPO
object has DACL_SECURITY_INFORMATION bit (0x04) set, users will
be prompted for ACL correction if ACLs inconsistency between AD
GPO and SYSVOL is detected when a GPO node is selected. You
should check the attribute for the GOP object in AD.
Problem #3:
This is basically the same logic as in (2). The "Add" and "Remove"
buttons in Delegation dialog are enabled only when the attribute
sDRightsEffective of selected GPO object has
DACL_SECURITY_INFORMATION (0x04) bit set. You should check the
attribute for the GOP object in AD.
Yeah for this it seems that the obvious problem is the lack of
sDRightsEffective in SAMBA 4.
Debugging Information:
By the way, you can follow the instruction in this link
(http://technet.microsoft.com/en-us/library/cc737379(WS.10).aspx
) to enable GPMC logging, if you want to troubleshoot the issues
related to operations in GPMC. For example, the logging will show
you in which step the consistency checking fails.
You can look for the text "CGPMGPO::IsAclConsistent()" in the
logs generated.
If you need more information, please let us know.
Thanks!
Matthieu.
