<title>NT Domain RPC's</title>

<sect1>
<title>Introduction</title>


<para>
This document contains information to provide an NT workstation with login
services, without the need for an NT server. It is the sgml version of <ulink url="http://mailhost.cb1.com/~lkcl/cifsntdomain.txt">http://mailhost.cb1.com/~lkcl/cifsntdomain.txt</ulink>, controlled by Luke.
</para>

<para>
It should be possible to select a domain instead of a workgroup (in the NT
workstation's TCP/IP settings) and after the obligatory reboot, type in a
username, password, select a domain and successfully log in.  I would
appreciate any feedback on your experiences with this process, and any
comments, corrections and additions to this document.
</para>

<para>
The packets described here can be easily derived from (and are probably
better understood using) Netmon.exe.  You will need to use the version
of Netmon that matches your system, in order to correctly decode the
NETLOGON, lsarpc and srvsvc Transact pipes.  This document is derived from
NT Service Pack 1 and its corresponding version of Netmon.  It is intended
that an annotated packet trace be produced, which will likely be more
instructive than this document.
</para>

<para>
Also needed, to fully implement NT Domain Login Services, is the 
document describing the cryptographic part of the NT authentication.
This document is available from comp.protocols.smb; from the ntsecurity.net
digest and from the samba digest, amongst other sources.
</para>

<para>
A copy is available from:

A c-code implementation, provided by <ulink url="mailto:linus@incolumitas.se">Linus Nordberg</ulink>
of this protocol is available from:

<para>
Also used to provide debugging information is the Check Build version of
NT workstation, and enabling full debugging in NETLOGON.  This is
achieved by setting the following REG_SZ registry key to 0x1ffffff:
</para>

<para><filename>HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters</filename></para>

<para><emphasis>Incorrect direct editing of the registry can cause your
machine to fail. Then again, so can incorrect implementation of this 
protocol. See "Liability:" above.</emphasis></para>

<para>
Bear in mind that each packet over-the-wire will have its origin in an
API call.  Therefore, there are likely to be structures, enumerations
and defines that are usefully documented elsewhere.
</para>

<para>
This document is by no means complete or authoritative.  Missing sections
include, but are not limited to:
</para>


<orderedlist>

<listitem><para>Mappings of RIDs to usernames (and vice-versa).</para></listitem>

<listitem><para>What a User ID is and what a Group ID is.</para></listitem>

<listitem><para>The exact meaning/definition of various magic constants or enumerations.</para></listitem>

<listitem><para>The reply error code and use of that error code when a
workstation becomes a member of a domain (to be described later).  
Failure to return this error code will make the workstation report 
that it is already a member of the domain.</para></listitem>

<listitem><para>the cryptographic side of the NetrServerPasswordSet command, 
which would allow the workstation to change its password.  This password is
used to generate the long-term session key.  [It is possible to reject this
command, and keep the default workstation password].</para></listitem>

<title>Notes and Structures</title>

<sect2>
<title>Notes</title>

<orderedlist>
<listitem><para>
In the SMB Transact pipes, some "Structures", described here, appear to be
4-byte aligned with the SMB header, at their start.  Exactly which
"Structures" need aligning is not precisely known or documented.
</para></listitem>

<listitem><para>
In the UDP NTLOGON Mailslots, some "Structures", described here, appear to be
2-byte aligned with the start of the mailslot, at their start.
</para></listitem>

<listitem><para>
Domain SID is of the format S-revision-version-auth1-auth2...authN.
e.g S-1-5-123-456-789-123-456.  the 5 could be a sub-revision.
</para></listitem>

<listitem><para>
any undocumented buffer pointers must be non-zero if the string buffer it
refers to contains characters.  exactly what value they should be is unknown.
0x0000 0002 seems to do the trick to indicate that the buffer exists.  a
NULL buffer pointer indicates that the string buffer is of zero length.
If the buffer pointer is NULL, then it is suspected that the structure it
refers to is NOT put into (or taken out of) the SMB data stream.  This is
empirically derived from, for example, the LSA SAM Logon response packet,
where if the buffer pointer is NULL, the user information is not inserted
into the data stream.  Exactly what happens with an array of buffer pointers
is not known, although an educated guess can be made.
</para></listitem>

<listitem><para>
an array of structures (a container) appears to have a count and a pointer.
if the count is zero, the pointer is also zero.  no further data is put
into or taken out of the SMB data stream.  if the count is non-zero, then
the pointer is also non-zero.  immediately following the pointer is the
count again, followed by an array of container sub-structures.  the count
appears a third time after the last sub-structure.

<title>MSRPC over Transact Named Pipe</title>

<para>For details on the SMB Transact Named Pipe, see cifs6.txt</para>

<sect2>
<title>MSRPC Pipes</title>

<para>
The MSRPC is conducted over an SMB Transact Pipe with a name of 
<filename>\PIPE\</filename>.  You must first obtain a 16 bit file handle, by
sending a SMBopenX with the pipe name <filename>\PIPE\srvsvc</filename> for
example.  You can then perform an SMB Trans,
and must carry out an SMBclose on the file handle once you are finished.
</para>

<para>
Trans Requests must be sent with two setup UINT16s, no UINT16 params (none
known about), and UINT8 data parameters sufficient to contain the MSRPC
header, and MSRPC data.  The first UINT16 setup parameter must be either
0x0026 to indicate an RPC, or 0x0001 to indicate Set Named Pipe Handle
state.  The second UINT16 parameter must be the file handle for the pipe,
obtained above.
</para>

<para>
The Data section for an API Command of 0x0026 (RPC pipe) in the Trans
Request is the RPC Header, followed by the RPC Data.  The Data section for
an API Command of 0x0001 (Set Named Pipe Handle state) is two bytes.  The
only value seen for these two bytes is 0x00 0x43.
</para>

<para>
MSRPC Responses are sent as response data inside standard SMB Trans
responses, with the MSRPC Header, MSRPC Data and MSRPC tail.
</para>

<para>
It is suspected that the Trans Requests will need to be at least 2-byte
aligned (probably 4-byte).  This is standard practice for SMBs.  It is also
independent of the observed 4-byte alignments with the start of the MSRPC
header, including the 4-byte alignment between the MSRPC header and the
MSRPC data.
</para>

<para>
First, an SMBtconX connection is made to the IPC$ share.  The connection
must be made using encrypted passwords, not clear-text.  Then, an SMBopenX
is made on the pipe.  Then, a Set Named Pipe Handle State must be sent,
after which the pipe is ready to accept API commands.  Lastly, and SMBclose
is sent.
</para>

<para>
To be resolved:
</para>

<para>
lkcl/01nov97 there appear to be two additional bytes after the null-terminated \PIPE\ name for the RPC pipe.  Values seen so far are
listed below:</para>

anyone listening in on the network as the machine password has a well
known value. Until the machine is rebooted it will use this session
key to encrypt NT and LM one way functions of passwords which are
password equivalents. Any user who logs in before the machine has been
rebooted a second time will have their password equivalent exposed. Of
course the new machine password is exposed at this time anyway.
</para>

<para>
None of the returned user info such as logon script, profile path and
SIDs *appear* to be protected by anything other than the TCP checksum.
</para>

<para>
The server time stamps appear to be ignored.
</para>

<para>
The client sends a ReturnAuthenticator in the SamLogon request which I
can't find a use for.  However its time is used as the timestamp
returned by the server.
</para>

<para>
The password OWFs should NOT be sent over the network reversibly
encrypted. They should be sent using ARC4(Ks,md4(owf)) with the server
computing the same function using the owf values in the SAM.

<title>SIDs and RIDs</title>

<para>
SIDs and RIDs are well documented elsewhere.
</para>

<para>
A SID is an NT Security ID (see DOM_SID structure).  They are of the form:
</para>

<simplelist>
<member>revision-NN-SubAuth1-SubAuth2-SubAuth3... </member>
<member>revision-0xNNNNNNNNNNNN-SubAuth1-SubAuth2-SubAuth3...</member>
</simplelist>

<para>
currently, the SID revision is 1.
The Sub-Authorities are known as Relative IDs (RIDs).
