Subject: [cifs-protocol] Question about [MS-DRSR] section 5.12.2 - prefixMap 
implementation

Hi,

I need a clarification about what are the differences between prefixMap 
implementation for Win2K3 and Win2K8(R2).

Attached you may find:
1. LDIF file to provision AD Schema with some test Attributes - OIDs of those 
attributes are crafted so that different scenarios could be tested.
2. Log files gathered during execution of Samba's RPC-DSSYNC test against 
Win2K3 and Win2K8. I am sending the log files as Word documents so it is easy 
for me to highlight interesting parts from the log files.
  -- prefixMap received is highlighted with 'gray'; newly added entries are 
highlighted with 'yellow'
  -- newly added object attributes received are also highlighted with 'yellow'
3. For testing I was using:
  -- Win2k3 R2 - Domain functional level = Win 2000 installation
  -- Win2K8 R2 - Domain functional lever = Win 2008 R2
  -- Samba 4 - latest build. Test run is RPC-DSSYNC. 
     Command line for testing: 
     $> bin/smbtorture -Uadministrator%333 
--configfile=/usr/local/samba/etc/drsuapi.conf 
ncacn_ip_tcp:Win_machine_ip[print,seal] RPC-DSSYNC -d1

As you may see, for Win2K3 everything works correctly as described in MS-DRSR, 
section 5.12.2.
I.e. attribute with attid=0x1B860001 matches prefixMap entry with id=0x00001b86 
and thus Attribute OID is correctly decoded as being '1.2.250.1'

In Win2k8 log file however, for attid=0x85C6D3B9 matching prefixMap entry 
should be id=0x00004823 and it is not quite obvious how 0x85C6D3B9 is matched 
to 0x00004823?

Please, clarify what is the algorithm used under Win2k8 for MakeAttid() and 
OidFromAttid() functions?

Many thanks in advance.

Kamen Mazdrashki
