b4abd3faaf s3-auth: remove "security=server" (depricated since 3.6)
"security=server" has a lot of problems in the world with
modern security (ntlmv2 and krb5). It was also not very
reliable, as it needed a stable connection to the password
server for the lifetime of the whole client connection!

Please use "security=domain" or "security=ads" is you
authentication against remote servers (domain controllers).

77602d877e s3-auth: Remove single-implementation plugin layer
The ->get_ntlm_challenge and ->check_ntlm_password elements of struct auth_context
were only ever initialised to a single value.  Make it easier to follow by
just calling the function directly.

d7bb961859 s3-auth: Remove security=share (depricated since 3.6).
This patch removes security=share, which Samba implemented by matching
the per-share password provided by the client in the Tree Connect with
a selection of usernames supplied by the client, the smb.conf or
guessed from the environment.

The rationale for the removal is that for the bulk of security=share
users, we just we need a very simple way to run a 'trust the network'
Samba server, where users mark shares as guest ok.  This is still
supported, and the smb.conf options are documented at
https://wiki.samba.org/index.php/Public_Samba_Server

At the same time, this closes the door on one of the most arcane areas
of Samba authentication.

Naturally, full user-name/password authentication remain available in
security=user and above.

This includes documentation updates for username and only user, which
now only do a small amount of what they used to do.

8a9b6fe26d s3-auth: Add a way to get an auth4_context from the auth stack
This will allow us to use the same layer that auth_ntlmssp does
in the non-SPNEGO session setup, which will in turn make the
authentication code more consistent in the AD server case.

23994e1b53 s3:auth Make Samba3 use the new common struct auth_usersupplied_info
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.

2203bed32c r13576: This is the beginnings of moving the SAM_ACCOUNT data structure
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......
