lp_load() could not be called multiple times to modify parameter settings based
on reading from multiple configuration settings. Each time, it initialized all
of the settings back to their defaults before reading the specified
configuration file.
This patch adds a parameter to lp_load() specifying whether the settings should
be initialized. It does, however, still force the settings to be initialized
the first time, even if the request was to not initialize them. (Not doing so
could wreak havoc due to uninitialized values.)

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.

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'

there is SYS_utimes syscall defined at compile time in glibc-kernheaders but
it is available on 2.6 kernels only. Therefore, we can't rely on syscall at
compile time but have to check that behaviour during program execution. An easy
workaround is to have replacement for utimes() implemented within our wrapper and
do not rely on syscall at all. Thus, if REPLACE_UTIME is defined already (by packager),
skip these syscall shortcuts.

This protocol looks rather like SMTP headers/LDAP:
NT-Domain: TESTWG
Username: abartlet
...
Password: foo
Challenge-response passwords are in hexideciaml, while any 'plain'
string can be base64 encoded when like this:
Password:: Zm9vCg==
(the :: indicates it, just like LDAP - I hope)
The protocol is not final, so it is #ifdef DEVELOPER for now (so
nobody starts to rely on it until I'm happy), but we may as well get
this into subversion.
My intention is to use this to power the next version of my
PPP/ntlm_auth plugin, and hopefully entice a FreeRadius plugin out of
the woods.

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...

Winbind tickets expired. We now check the expiration time, and acquire
new tickets. We couln't rely on renewing them, because if we didn't get
a request before they expired, we wouldn't have renewed them. Also, there
is a one-week limit in MS on renewal life, so new tickets would have been
needed after a week anyway. Default is 10 hours, so we should only be
acquiring them that often, unless the configuration on the DC is changed (and
the minimum is 1 hour).

domains, this patch ensures that we always use the ADS backend when
security=ADS, and the remote server is capable.
The routines used for this behaviour have been upgraded to modern Samba
codeing standards.
This is a change in behaviour for mixed mode domains, and if the trusted
domain cannot be reached with our current krb5.conf file, we will show
that domain as disconnected.
This is in line with existing behaviour for native mode domains, and for
our primary domain.
As a consequence of testing this patch, I found that our kerberos error
handling was well below par - we would often throw away useful error
values. These changes move more routines to ADS_STATUS to return
kerberos errors.
Also found when valgrinding the setup, fix a few memory leaks.
While sniffing the resultant connections, I noticed we would query our
list of trusted domains twice - so I have reworked some of the code to
avoid that.

Instead of returning a name in DOMAIN\user format, we now return it in the
same way that nsswtich does - following the rules of 'winbind use default

on, to match back to their unix usernames.

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)

- 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...
