It's important to have them separated from make_{server,session}_info_guest(),
because there's a fundamental difference between anonymous (the client requested
no authentication) and guest (the server lies about the authentication failure).
When it's really an anonymous connection, we should reflect that in the
resulting session info.
This should fix a problem where Windows 10 tries to join
a Samba hosted NT4 domain and has SMB2/3 enabled.
We no longer return SMB_SETUP_GUEST or SMB2_SESSION_FLAG_IS_GUEST
for true anonymous connections.
The commit message from a few commit before shows the resulting
auth_session_info change.

This ensures that gensec, and then the NTLM auth subsystem under it, always gets the
remote and local address pointers for potential logging.
The local address allows us to know which interface an authentication is on

With NTLMSSP, for NTLM2 we need to be able to set the effective challenge,
so if we ever did use a module that needed this functionlity, we would
downgrade to just NTLM.
Now that security=server has been removed, we have no such module.
This will make it easier to make the auth subsystem async, as we will
not need to consider making .get_challenge async.
Andrew Bartlett
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 matches check_ntlm_password() and generate_session_info_pac()

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.

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.

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 function handles more than NTLMSSP now, at least when we are an AD DC
and so changing the name may avoid some confusion in the future.

This avoids keeping the event context around on a the gensec_security
context structure long term.
In the Samba3 server, the event context we either supply is a NULL
pointer as no server-side modules currently use the event context.

to the parts of ntlmssp_wrap.c that are now not called.

There is no longer any theft of memory as the underlying routines now
produce a new auth_session_info for this caller, allocating it
on the supplied memory context.
Andrew Bartlett
Rather than passing this value around the callers, and eventually
setting it in register_existing_vuid(), we simply pass it to
create_local_token(). This also removes the need for
auth_ntlmssp_get_username().

This helps map on to the GENSEC semantics better, and ensures that the

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.
