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

We already confirm that we have this functionality before we set HAVE_KRB5 at
configure time.

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.

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.

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.

These operate on NTLM authentication, so make that clear.

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 matches check_ntlm_password() and generate_session_info_pac()

gensec_ntlmssp_server_start()

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

auth4_context
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.

Replaced the undescriptive SMB_PORT1 and SMB_PORT2 defined constants
with the slightly more descriptive names NBT_SMB_PORT and TCP_SMB_PORT.
Also replaced several hard-coded references to the well-known port
numbers (139 and 445, respectively) as appropriate.
Small changes to clarify some comments regarding the two transport
types.

gensec_ntlmssp does not need to know the internal form of the
struct user_info_dc or auth_serversupplied_info. This will allow the
calling logic to be put in common.

This is causing circular depdnendcies that bring libpdb in all code and this is
BAD.
This change 'protects' the sid and guid of the domain by adding a special key
that makes them effectively read only.
Limit this temporarily to the samba 4 build, once it gets some good testing the
samba4 ifdefs can be dropped.

This matches the auth_ntlmssp case and the smbd/sesssetup.c code.

This simplifies a lot of code, as we know we are always dealing with a
struct gensec_security, and allows the gensec module being used to
implement GSSAPI to be swapped when required for AD-server operation.
