GENSEC has the concept of starting the GENSEC subsystem before starting the
actual mechansim. Between these two stages is when most context methods
are called, to specify credentials and features.

This will allow auth plugins such as auth_samba4 to provide an initialised
GENSEC context to auth subsystem callers.

This common structure will make it much easier to produce an auth
module for s3compat that calls Samba4's auth subsystem.
In order the make the link work properly (and not map twice), we mark
both that we did try and map the user, as well as if we changed the
user during the mapping.

Turn the freeing function into a destructor and attach it to the
auth_context.
Make all callers TALLOC_FREE() the auth_context instead of calling
the free function.

This is closer to the structure I want for a common struct
auth_usersupplied_info.

This helps with the upcoming NTLMSSP merge, and allows errors to be returned.

str_list_make(). From Dan Sledz <dan.sledz@isilon.com>:
In samba 3.2 passing NULL or an empty string returned NULL.
In master, it now returns a list of length 1 with the first string set
to NULL (an empty list).

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......

This re-enables the Samba 2.2 behavior where a user that was
successfully authenticated by a remote DC would be mapped
to the guest account if there was not existing UNIX account
for that user and we could not create 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().

- 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...
