the schannel code, but I've included that anyway. :-)
This patch revives the client-side NTLMSSP support for RPC named pipes
in Samba, and cleans up the client and server schannel code. The use of the
new code is enabled by the 'sign', 'seal' and 'schannel' commands in
rpcclient.
The aim was to prove that our separate NTLMSSP client library actually
implements NTLMSSP signing and sealing as per Microsoft's NTLMv1 implementation,
in the hope that knowing this will assist us in correctly implementing
NTLMSSP signing for SMB packets. (Still not yet functional)
This patch replaces the NTLMSSP implementation in rpc_client/cli_pipe.c with
calls to libsmb/ntlmssp.c. In the process, we have gained the ability to
use the more secure NT password, and the ability to sign-only, instead of
having to seal the pipe connection. (Previously we were limited to sealing,
and could only use the LM-password derived key).
Our new client-side NTLMSSP code also needed alteration to cope with our
comparatively simple server-side implementation. A future step is to replace
it with calls to the same NTLMSSP library.
Also included in this patch is the schannel 'sign only' patch I submitted to
the team earlier. While not enabled (and not functional, at this stage) the
work in this patch makes the code paths *much* easier to follow. I have also
included similar hooks in rpccleint to allow the use of schannel on *any* pipe.
rpcclient now defaults to not using schannel (or any other extra per-pipe
authenticiation) for any connection. The 'schannel' command enables schannel
for all pipes until disabled.
This code is also much more secure than the previous code, as changes to our
cli_pipe routines ensure that the authentication footer cannot be removed
by an attacker, and more error states are correctly handled.
(The same needs to be done to our server)

strupper_m/strlower_m.
I really want people to think about when they're using multibyte strings.

With big thanks to tpot for the ethereal disector, and for the base code
behind this, we now fully support NTLMv2 as a client.
In particular, we support it with direct domain logons (tested with ntlm_auth
--diagnostics), with 'old style' session setups, and with NTLMSSP.
In fact, for NTLMSSP we recycle one of the parts of the server's reply directly...
(we might need to parse for unicode issues later).
In particular, a Win2k domain controller now supplies us with a session key
for this password, which means that doman joins, and non-spnego SMB signing
are now supported with NTLMv2!

key, so we can test it in ntlm_auth.
I suspect the 'lm' version doesn't exist, but it's easy to change back.

NTLM Authentication:
- Add a 'privileged' mode to Winbindd. This is achieved by means of a directory
under lockdir, that the admin can change the group access for.
- This mode is now required to access with 'CRAP' authentication feature.
- This *will* break the current SQUID helper, so I've fixed up our ntlm_auth
replacement:
- Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a
challenge.
- Use this to make our ntlm_auth utility suitable for use in current Squid 2.5
servers.
- Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates
are needed.
- Now uses fgets(), not x_fgets() to cope with Squid environment (I think
somthing to do with non-blocking stdin).
- Add much more robust connection code to wb_common.c - it will not connect to
a server of a different protocol version, and it will automatically try and
reconnect to the 'privileged' pipe if possible.
- This could help with 'privileged' idmap operations etc in future.
- Add a generic HEX encode routine to util_str.c,
- fix a small line of dodgy C in StrnCpy_fn()
- Correctly pull our 'session key' out of the info3 from th the DC. This is
used in both the auth code, and in for export over the winbind pipe to
ntlm_auth.
- Given the user's challenge/response and access to the privileged pipe,
allow external access to the 'session key'. To be used for MSCHAPv2
integration.

- new kerberos code, allowing the account to change it's own password
without special SD settings required
- NTLMSSP client code, now seperated from cliconnect.c
- NTLMv2 client code
- SMB signing fixes

The idea here is to seperate, as much as possible, the SPNEGO layer from the
NTLMSSP layer. This not only helps us with protocol correctness, but also
should allow further mechinisms to be added with relitive ease. I indend to
make the kerberos code use this shortly.
I've never seen the 'zero length blob' form of the anonymous login, so I've
removed that case.

Change the 'cookie' to be the ntlmssp_context, and use the 'auth_context' on
that to store the cookie. Ensures that simple callbacks can 'just work'.
Also make it clear that we are doing a pull_string into a pstring, not just
any sized buffer.

eliminate the dependency on the auth subsystem. The next step is to add
the required code to 'ntlm_auth', for export to Squid etc.
