<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I have 4 attributes received – all grouped above.<o:p></o:p></p>
<p class=MsoPlainText>For the first one I got ATTID: 0x8933929C<o:p></o:p></p>
<p class=MsoPlainText>If we follow the logic in OidFromAttid(), then first we
are to find a prefixMap entry with id_prefix: 0x0000008933<o:p></o:p></p>
<p class=MsoPlainText>Well, there is no such entry (please look in log file for
Win2k8).<o:p></o:p></p>
<p class=MsoPlainText>prefixMap entry we should find for this ATTID is
id_prefix: 0x00004823. So let’s pretend, that 0x8933 is somehow mapped to
0x4823 and try to make full binary-oid of the Attribute.<o:p></o:p></p>
<p class=MsoPlainText>According to docs, I should add the lo-word for ATTID,
e.g. 0x929C, to the partial binary-oid in the prefixMap - 0x2A817A.<o:p></o:p></p>
<p class=MsoPlainText>When I do this, I got OID='1.2.250.4764' instead of
'1.2.250.1'.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Btw, in order to not making all those calculations by
hand every time, I’ve created a little Python script to do the job. <o:p></o:p></p>
<p class=MsoPlainText>So, if you have a Python installed, you can just ‘import
prefixmap’ in Python console and then execute
prefixmap.oid_from_attid('0x2A817A', '0x8933929C') – it will return
'1.2.250.4764'. Prefix map module implements algorithms described in MS-DRSR.<o:p></o:p></p>
<p class=MsoPlainText>I am attaching the Python script also if you want to play
with it.<o:p></o:p></p>

<p class=MsoPlainText>> Good morning again Kamen. I have completed my
investigation of our<o:p></o:p></p>
<p class=MsoPlainText>> prefixMap, MakeAttid() and OidFromAttid() on Windows
2003 & 2008 R2:<o:p></o:p></p>
<p class=MsoPlainText>> they are indeed functionally identical.<o:p></o:p></p>
<p class=MsoPlainText>> <o:p></o:p></p>
<p class=MsoPlainText>> So, something else is going on here, and we will
need to duplicate your<o:p></o:p></p>
<p class=MsoPlainText>> results under debug. To do that, I need to ask you
to forward a copy of<o:p></o:p></p>
<p class=MsoPlainText>> the LDIF file to me (I received the docs & conf

<p class=MsoPlainText>> Hi Bill,<o:p></o:p></p>
<p class=MsoPlainText>> <o:p></o:p></p>
<p class=MsoPlainText>> Currently this issue stops me from implementing
MakeAttid() and<o:p></o:p></p>
<p class=MsoPlainText>> OidFromAttid() to work transparently in all cases -
from Win2k3 to<o:p></o:p></p>
<p class=MsoPlainText>> Win2k8. Also I can't make a reasonable unit test for
those functions.<o:p></o:p></p>
<p class=MsoPlainText>> Nevertheless, it is not a 'show stopper' for me at
this stage, as<o:p></o:p></p>
<p class=MsoPlainText>> current implementation (following MS-DRSR) work well
for Win2k3 and<o:p></o:p></p>
<p class=MsoPlainText>> Win2k8 (without modifying schema).<o:p></o:p></p>
<p class=MsoPlainText>> <o:p></o:p></p>
<p class=MsoPlainText>> Attached you may find:<o:p></o:p></p>
<p class=MsoPlainText>> - LDIF file;<o:p></o:p></p>
<p class=MsoPlainText>> - 2 logs - from Win2k3 (Functional Level = Win
2000) and Win2k8-R2<o:p></o:p></p>
<p class=MsoPlainText>> (Functional Level = Win 2008 R2);<o:p></o:p></p>
<p class=MsoPlainText>> - smb conf file used for testing, in case you
want to try it by<o:p></o:p></p>
<p class=MsoPlainText>> yourself<o:p></o:p></p>
<p class=MsoPlainText>> <o:p></o:p></p>
<p class=MsoPlainText>> I am currently on making an resume for Win2k8 result
I got from windows<o:p></o:p></p>
<p class=MsoPlainText>> server.<o:p></o:p></p>
<p class=MsoPlainText>> <o:p></o:p></p>
<p class=MsoPlainText>> It seems not to be a corner case to me.<o:p></o:p></p>
<p class=MsoPlainText>> It seems more like a special case for Win2k8 -
ATTIDs for all newly<o:p></o:p></p>
<p class=MsoPlainText>> created attributes are with 31-th bit set.<o:p></o:p></p>
