Not yet. (and at this sage I think I would prefer to pase the NTLM<br />
blobs in Samba, but perhaps either use Heimdal's bulk sign/seal code, or<br />
provide the whole mech).<br />

<br />
Something where you gss_import_sec_context() a context emitted by <br />
Samba, and use Heimdal for sign/seal? When you say "provide the whole <br />
mech" do you mean Samba or Heimdal provide the whole mech?<br />
<br />
Is your desire for NTLM in GSS so that OpenLDAP / FDS can work with <br />
NTLM? Or are you moving gensec towards GSS? Or have I misunderstood <br />
you? :-)<br />
<br />

Luke: Are you using Heimdal's NTLM implementation in Samba 4?<br />
Luke: Do you provide your own "struct ntlm_server_interface"?<br />
<br />
Andrew: Not yet. (and at this sage I think I would prefer to pass<br />
Andrew: the NTLM blobs in Samba, but perhaps either use Heimdal's <br />
Andrew: bulk sign/seal code, or provide the whole mech).<br />
<br />
Luke: Something where you gss_import_sec_context() a context <br />
Luke: emitted by Samba, and use Heimdal for sign/seal? <br />
<br />
That's one idea. Or providing 'credentials' that tells Heimdal<br />
to pass whole blobs (not the NTLM challenge/response + username)<br />
to Samba to parse and validate. <br />
<br />
Luke: When you say "provide the whole mech" do you <br />
Luke: mean Samba or Heimdal provide the whole mech?<br />
<br />
I wondered if, as there is a renewed interest in 'NTLMSSP done right'<br />
from GD, that we might provide a full mechglue mechansim to be loaded<br />
from Heimdal. <br />
<br />
Luke: Is your desire for NTLM in GSS so that OpenLDAP / FDS can work with <br />
Luke: NTLM? Or are you moving gensec towards GSS? Or have I misunderstood <br />
Luke: you? :-)<br />
<br />
I have a number of conflicting desires for NTLM:<br />
<br />
- An 'NTLM done right' that other clients/servers could use. <br />
Pointing folks at Heimdal's NTLM lib might mean they abandon <br />
poorly written libs that assume unicide is ASCII+\0. <br />

Andrew: That's one idea. Or providing 'credentials' that tells<br />
Andrew: Heimdal to pass whole blobs (not the NTLM challenge/<br />
Andrew: response + username) to Samba to parse and validate.<br />
<br />
So I prefer moving the NTLM parsing to somewhere in Heimdal code,<br />
and just use something like NetrLogonSamLogonEx() for the backend<br />
auth, since that already exists for Windows with pass-through mode <br />
and Open Directory (Mac OS X server and client).<br />
<br />
Luke: When you say "provide the whole mech" do you <br />
Luke: mean Samba or Heimdal provide the whole mech?<br />
<br />
Andrew: I wondered if, as there is a renewed interest in 'NTLMSSP<br />
Andrew: done right' from GD, that we might provide a full mechglue<br />
Andrew: mechansim to be loaded from Heimdal.<br />
<br />
I'll eventually have a complete NTLMSSP, at least one to support<br />
smb and related protocols. What I have today talks to smbclient<br />
and and apple smb<br />
<br />
Luke: Is it your desire for NTLM in GSS that OpenLDAP / FDS can<br />
Luke: work with NTLM? Or are you moving gensec towards GSS?<br />
Luke: Or have I misunderstood you? :-)<br />
<br />
Andrew: I have a number of conflicting desires for NTLM:<br />
Andrew: - An 'NTLM done right' that other clients/servers could use.<br />
Andrew: Pointing folks at Heimdal's NTLM lib might mean they<br />
Andrew: abandon poorly written libs that assume unicide is ASCII+\0.<br />
<br />
Yeah, not really done with that yet, always the fun with that<br />
backend unicode library.<br />
<br />
One more missing thing: format of NTLM exported name.<br />
<br />
Andrew: - The ability to use Heimdal's SPNEGO code. SPGNEGO is<br />
Andrew: very tied to Kerberos, particularly for the new actually<br />
Andrew: secure version. Samba has to get at quite a bit of info<br />

<br />
yay.<br />
<br />
Andrew: - The thought that we could offload NTLM onto<br />
Andrew: an external crypto lib,that just works.<br />
<br />
I get the NTLMv1 crypto right today, the NTLMv2 is not there,<br />
but I have not had a reason to fix it yet.<br />

If you support NetrLogonSamLogonEx() you should be fine for the<br />
server, for the client I have a credcache manager that's based<br />
on KCM.<br />

When I talked to Larry [Zhu] in Stockholm, we kind of agreed<br />
that PK-U2U in password mode would do it if there is a local<br />
kerberos database on the windows clients. I guess we should<br />
follow this up.<br />

You're going to implement NetrLogonSamLogonEx() in Heimdal?<br />
Or leave that to Samba?<br />

The heimdal equivalent (but more secure :) is the digest server <br />
interface.<br />
<br />
It's more secure since the server doesn't get to choose the <br />
nonce (thus can't do a replay on another server's packets). <br />
This is important since the heimdal digest protocol supports<br />
ticket delegation as a side effect.<br />
<br />
I've got a version which is pretty much just like<br />
NetrLogonSamLogonEx() though.<br />

<br />
But Windows servers don't support the Heimdal interface, and<br />
isn't interoperability with existing Windows deployments <br />
important to most NTLM consumers?<br />
