talloc_free()'ed at the end of a session.
Rework the passwd cache code to use talloc_unlink and
talloc_reference, to more carefully manage the cache.

password at next logon" code. The "password last set time" of zero now
means "user must change password", because that's how windows seems to
use it. The "can change" and "must change" times are now calculated
based on the "last set" time and policies.
We use the "can change" field now to indicate that a user cannot change
a password by putting MAX_TIME_T in it (so long as "last set" time isn't
zero). Based on this, we set the password-can-change bit in the
faked secdesc.

to make full use of the new talloc() interface. Discussed with Volker
and Jeremy.
* remove the internal mem_ctx and simply use the talloc()
structure as the context.
* replace the internal free_fn() with a talloc_destructor() function
* remove the unnecessary private nested structure
* rename SAM_ACCOUNT to 'struct samu' to indicate the current an
upcoming changes. Groups will most likely be replaced with a
'struct samg' in the future.
Note that there are now passbd API changes. And for the most
part, the wrapper functions remain the same.
While this code has been tested on tdb and ldap based Samba PDC's
as well as Samba member servers, there are probably still
some bugs. The code also needs more testing under valgrind to
ensure it's not leaking memory.
But it's a start......

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 used to be commit 724e8d3f33719543146280062435c69a835c491e)
For a (very) long time, we have had a bug in Samba were an NTLMv2-only
PDC would fail, because it converted the password into NTLM format for
checking.
This patch performs the direct comparison required for interactive
logons to function in this situation. It also removes the 'auth flags', which
simply where not ever used.
Natrually, this plays with the size of structures, so rebuild, rebuild
rebuild...

subsystem into a seperate file - ntlm_check.c.
This allows us to call these routines from ntlm_auth. The purpose of this
exercise is to allow ntlm_auth (when operating as an NTLMSSP server) to
avoid talking to winbind. This should allow for easier debugging.
ntlm_auth itself has been reorgainised, so as to share more code between
the SPNEGO-wrapped and 'raw' NTLMSSP modes. A new 'client' NTLMSSP mode
has been added, for use with a Cyrus-SASL module I am writing (based on vl's
work)

The next move will be to remove our password checking code from the SAM
authentication backend, and into a file where other parts of samba can use
it.
The ntlm_auth changes provide for better use of common code.

- 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...

me to review it).
This patch works well for a DC running with trusted domains, becouse it lets
you check the local SAM first, but only for this domain's users.

password. On NT4, NT_STATUS_NOLOGON_INTERDOMAIN_TRUST_ACCOUNT means
the password was correct. So the PDC believed that he had his trust
account correctly added. Later the auth2 naturally failed.
BTW, setting up an interdom trust account is not what I would call
well documented and easy to handle... Working on that now :-)
