a copy of the plaintext password, only the NT and LM
hashes (all it needs). Fix smbencrypt to expose hash
verions of plaintext function. Andrew Bartlett, you
might want to look at this for gensec.
This should make it easier for winbindd to store
cached credentials without having to store plaintext
passwords in an NTLM-only environment (non krb5).

rpcclient-tester for some info-levels.
Jerry, I tried to adopt to prs_pointer() where possible and to not
interfere with your work for usrmgr.
- Add "net rpc trustdom vampire"-tool.
This allows to retrieve Interdomain Trust(ed)-Relationships from
NT4-Servers including cleartext-passwords (still stored in the local
secrets.tdb).
The net-hook was done in cooperation with Lars Mueller
<lmuelle@suse.de>.
To vampire trusted domains simply call:
net rpc trustdom vampire -S nt4dc -Uadmin%pass

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().

with more correct NTLMSSP support in client and server, but it will do
for now.
Also implement LANMAN password only in the classical session setup code, but
#ifdef'ed out. In Samba4, I'll make this run-time so we can torture it.
Lanman passwords over 14 dos characters long could be considered
'invalid' (they are truncated) - so SMBencrypt now returns 'False' if
it generates such a password.

another NTLMv2 combination.
We should allow the NTLMv2 response to be calculated with either the domain
as supplied, or the domain in UPPER case (as we always did in the past).
As a client, we always UPPER case it (as per the spec), but we also
make sure to UPPER case the domain, when we send it. This should give
us maximum compatability.

This fixes a problem joining a Samba domain from a
vanilla win2k client that doesn't set the
NTLMSSP_NEGOTIATE_NTLM2 flag.
Reported on samba ml as "decode_pw: incorrect password length"
when handling a samr_set_userinfo(23 or 24) RPC.

- 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...

NTLMSSP with "" username, NULL password), and add --machine-pass (-P) to
all of Samba's clients.
When connecting to an Active Directory DC, you must initiate the CIFS level
session setup with Kerberos, not a guest login. If you don't, your machine
account is demoted to NT4.

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)

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!

A much better SMB signing module, that allows for mulitple signing algorithms
and correctly backs down from signing when the server cannot sign the reply.
This also attempts to enable SMB signing on NTLMSSP connections, but I don't
know what NTLMSSP flags to set yet.
This would allow 'client use signing' to be set by default, for server
compatability. (A seperate option value should be provided for mandetory
signing, which would not back down).

This kills off the offending code in smbpasswd -j -Uab%c
In the process we have changed from unsing compelatly random passwords
to random, 15 char ascii strings. While this does produce a decrese in
entropy, it is still vastly greater than we need, considering the application.
In the meantime this allows us to actually *type* the machine account
password duruign debugging.
This code also adds a 'check' step to the join, confirming that the
stored password does indeed do somthing of value :-)

code.
In particular this assists tpot in some of his work, becouse it provides the
connection between the authenticaion and the vuid generation.
Major Changes:
- Fully malloc'ed structures.
- Massive rework of the code so that all structures are made and destroyed
using malloc and free, rather than hanging around on the stack.
- SAM_ACCOUNT unix uids and gids are now pointers to the same, to allow them
to be declared 'invalid' without the chance that people might get ROOT by
default.
- kill off some of the "DOMAIN\user" lookups. These can be readded at a more
appropriate place (probably domain_client_validate.c) in the future. They
don't belong in session setups.
- Massive introduction of DATA_BLOB structures, particularly for passwords.
- Use NTLMSSP flags to tell the backend what its getting, rather than magic
lenghths.
- Fix winbind back up again, but tpot is redoing this soon anyway.
- Abstract much of the work in srv_netlog_nt back into auth helper functions.
This is a LARGE change, and any assistance is testing it is appriciated.
Domain logons are still broken (as far as I can tell) but other functionality
seems
intact.
Needs testing with a wide variety of MS clients.

In particular this commit focuses on:
Actually adding the 'const' to the passdb interface, and the flow-on changes.
Also kill off the 'disp_info' stuff, as its no longer used.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
----
These changes introduces a large dose of 'const' to the Samba tree.
There are a number of good reasons to do this:
- I want to allow the SAM_ACCOUNT structure to move from wasteful
pstrings and fstrings to allocated strings. We can't do that if
people are modifying these outputs, as they may well make
assumptions about getting pstrings and fstrings
- I want --with-pam_smbpass to compile with a slightly sane
volume of warnings, currently its pretty bad, even in 2.2
where is compiles at all.
- Tridge assures me that he no longer opposes 'const religion'
based on the ability to #define const the problem away.
- Changed Get_Pwnam(x,y) into two variants (so that the const
parameter can work correctly): - Get_Pwnam(const x) and
Get_Pwnam_Modify(x).
- Reworked smbd/chgpasswd.c to work with these mods, passing
around a 'struct passwd' rather than the modified username
---
This finishes this line of commits off, your tree should now compile again :-)

out the error handling into a bunch of separate functions rather than all
being handled in one big function.
Fetch error codes from the last received packet:
void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num);
uint32 cli_nt_error(struct cli_state *);
Convert errors to UNIX errno values:
int cli_errno_from_dos(uint8 eclass, uint32 num);
int cli_errno_from_nt(uint32 status);
int cli_errno(struct cli_state *cli);
Detect different kinds of errors:
BOOL cli_is_dos_error(struct cli_state *cli);
BOOL cli_is_nt_error(struct cli_state *cli);
BOOL cli_is_error(struct cli_state *cli);
This also means we now support CAP_STATUS32 as we can decode and understand
NT errors instead of just DOS errors. Yay!
Ported a whole bunch of files in libsmb to use this new API instead of the
just the DOS error.
