The session key, after beeing set, was zeroed later on by the prs_init
in the CLI_DO_RPC macro.

logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT
or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes
the auth module interface to 2 (from 1). The effect of this is
that clients can access resources as a machine account if they
set these flags. This is the same as Windows (think of a VPN
where the vpn client authenticates itself to a VPN server
using machine account credentials - the vpn server checks
that the machine password was valid by performing a machine
account check with the PDC in the same was as it would a
user account check. I may add in a restriction (parameter)
to allow this behaviour to be turned off (as it was previously).
That may be on by default.
Andrew Bartlett please review this change carefully.

(this is the way it's been done in other functions). Instead
of moving this into the IDL, I think the best solution would
be to write a wrapper function around any call that needs
this (this is what we already do for many of the calls).

Andrew Bartlett is right - making lsa code do it the
netlogon way, not vica-versa.

Pass down the pipe_idx down to all functions in cli_pipe where nt_pipe_fnum is
referenced. First step towards having multiple pipes on a cli_struct. The idea
is to not have a single nt_pipe_fnum but an array for the pipes we support.

The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.

On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().

for setting up an schannel connection. This solves the problem
of a Samba DC running winbind, trusting a native mode AD domain,
and needing to enumerate AD users via wbinfo -u.

- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of data structures...
(This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)
- When connecting to the NETOGON pipe, we make a call to auth2, in order
to verify our identity. This call was being made with negotiation flags
of 0x1ff. This caused our account to be downgraded. If we instead make
the call with flags > 1ff (such as 0x701ff), then this does not occour.
- This is *not* related to the use of kerberos for the CIFS-level connection
My theory is that Win2k has a test to see if we are sending *exactly* what
NT4 sent - setting any other flags seems to cause us to remain intact.
Also ensure that we only have 'setup schannel' code in a few places, not
scattered around cmd_netlogon too.

important once we start doing schannel, as there would be a lot more
roundtrips for the second PIPE open and bind. With this patch logging
in to a member server is a matter of two (three if you count the
ack...) packets between us and the DC.

This allows us to join as a BDC, without appearing on the network as one
until we have the database replicated, and the admin changes the configuration.
This also change the SID retreval order from secrets.tdb, so we no longer
require a 'net rpc getsid' - the sid fetch during the domain join is sufficient.
Also minor fixes to 'net'.

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.

It does compile though :-).

This moves the rest of the functionality into the 'net rpc join' code.
Futhermore, this moves that entire area over to the libsmb codebase, rather
than the crufty old rpc_client stuff.
I have also fixed up the smbpasswd -a -m bug in the process.
We also have a new 'net rpc changetrustpw' that can be called from a
cron-job to regularly change the trust account password, for sites
that run winbind but not smbd.
With a little more work, we can kill rpc_client from smbd entirly!
(It is mostly the domain auth stuff - which I can rework - and the
spoolss stuff that sombody else will need to look over).

This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
