Good morning Nadya! I will begin work on this for you this morning. I have created the below case:

SRX091118600013 [MS-DTYP] 2.4.6 self relative form of SECURITY_DESCRIPTOR

Subject: Question about self relative form of SECURITY_DESCRIPTOR

Hello,
In MS-DTYP, section 2.4.6 (the table on page 55), the self relative format of a security descriptor is described as follows:
Revision
Sbz1
Control
OffsetOwner
OffsetGroup
OffsetSacl
OffsetDacl
OwnerSid
GroupSid
Sacl
Dacl

However, what we receive from the wire from a Win2003 or Win2008 is in fact in the form:
Revision
Sbz1
Control
OffsetOwner
OffsetGroup
OffsetSacl
OffsetDacl
Sacl
Dacl
OwnerSid
GroupSid

Although it does not prevent parsing the security descriptor, on a binary level the encoding between Windows and Samba is different, because Samba's is as documented. Is this the desired behavior or something that will be fixed?

Best Regards,
Nadezhda Ivanova
