This helps clarify the role of this structure and wrapper function.
The purpose here is to provide helper functions to the lib/param
loadparm_context that point back at the s3 lp_ functions. This allows
a struct loadparm_context to be passed to any point in the code, and
always refer to the correct loadparm system. If this has not been
set, the variables loaded in the lib/param code will be returned.
As requested by Michael Adam.

This is important in some situations where these queries might be
costly LDAP queries and is just not required for the system token.
This is because the system token should be just the NT
AUTHORITY\SYSTEM user and just enough unix info to allow the token to
be used.

This removes the duplication on how to detect that a user is system in Samba
now that the smbd system account is also only SID_NT_SYSTEM we can use the same

auth_netlogond was an important module in the development of the
combined Samba 4.0, and was the first module to link smbd with the AD
authentication store, showing that it was possible for NTLM
authentication to be offloaded to the AD server components.
We now have auth_samba4, which provides the full GENSEC stack to smbd,
which also matches exactly the group membership and privileges
assignment and which is supported and tested as part of the official
Samba 4.0 release configuration.

To cover all the enum values, ROLE_ACTIVE_DIRECTORY_DOMAIN_CONTROLLER
is mapped to the samba4 auth module, and this is no longer required to
be specified in fileserver.conf.

The SID for the SYSTEM token should be a fixed value, and not the
administrator. Note however that it will be replaced by the SID of
sec_initial_uid() by the create_local_token() code. Fixing this
requires fixes the other parts of the code that cannot cope with a
token of just SID_NT_SYSTEM.

This continues on from commit caaebb455cf955f66c2f662c53998c480cb2d6c9
which is marked as being part of bug #8944, ldapsam:trusted and ipasam
and an additional fix for bug #8567
(0528cb5f3a15b72dcb34ece21a3ffb3e7b8d6eb9).
The problem here was that the primary_gid was simply the pointer result
of dom_sid_parse_talloc() cast to a uint32_t (found by the IRIX cc on
the build farm).

System MIT krb5 build also enabled by specifying --without-ad-dc
When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level
configure in WAF build we are trying to detect and use system-wide MIT krb5
libraries. As result, Samba 4 DC functionality will be disabled due to the fact
that it is currently impossible to implement embedded KDC server with MIT krb5.
Thus, --with-system-mitkrb5/--without-ad-dc build will only produce
* Samba 4 client libraries and their Python bindings
* Samba 3 server (smbd, nmbd, winbindd from source3/)
* Samba 3 client libraries
In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture.
This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
"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).

The performance of these is minimal (these days) and they can return
invalid results when used as part of applications that do not use

On LSA and SAMR pipes session_key is truncated to 16 byte when doing encryption/decryption.
However, this was not done for trusted domain-related modifying operations.
As result, Samba 4 client libraries do not work against Samba 3 while working
against Windows 2008 r2.
Solved this by introducing "session_extract_session_key()" function that allows to specify
intent of use of the key.

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.
Andrew Bartlett
This patch ensures consistency in behaviour between NTLMSSP and NTLM
session setup handlers. By calling the same layer that auth_ntlmssp
calls, we can not only allow redirection of all authentication to the
AD DC, we ensure that map to guest and username map handling is
consistent, even in the file server alone.
Andrew Bartlett
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.

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.

This crypto is incredibly poor, and can technically be enabled on an otherwise more
secure connection that uses NTLM for the actual authentication leg. Therefore
disable it by default.

This is possible because we now supply the auth4_context abstraction that this
code is looking for.
Andrew Bartlett
Signed-off-by: Stefan Metzmacher <metze@samba.org>
This avoids creating a second auth_context, as it is a private pointer
in the auth4_context that has already been passed in, and makes the
gensec_ntlmssp code agnostic to the type of authentication backend
behind it. This will in turn allow the ntlmssp server code to be
further merged.
