6aaa124563 s4-auth: Do not supply the LM hash to the AD DC authentication code
This still passes in the value in the LM field for checking
in case it is an NT response or LMv2.

40f2070d3b s4:auth: let authenticate_ldap_simple_bind() pass down the mapped nt4names
authenticate_ldap_simple_bind*() needs to pass the
result of the cracknames operation into the auth stack
as user_info->client.{account,domain}_name, because
user_info->client.{account,domain}_name is also used
when forwarding the request via netrLogonSamLogon*
to a remote server, for exactly that the values are
also used in order to map a AUTH_PASSWORD_PLAIN into
AUTH_PASSWORD_RESPONSE, where the NTLMv2 response
contains the account and domain names passed in the
netr_IdentityInfo value.

Otherwise it would not be possible to forward the
LDAP simple bind authentication request to a remote
DC.

Currently this only applies to an RODC that forwards
the request to an RWDC.

But note that LDAP simple binds (as on Windows) only
work for users in the DCs forest, as the DsCrackNames
need to work and it can't work for users of remote
forests. I tested that in a DC of a forest root domain,
if rejected the LDAP simple bind against a different forest,
but allowed it for a users of a child domain in the
same forest. The NTLMSSP bind worked in both cases.

c7b8c71b2b s4:auth: check for user_info->mapped.account_name if it needs to be filled
mapped_state is a special hack for authenticate_ldap_simple_bind_send()
in order to avoid some additional work in authsam_check_password_internals().

But that code will be changed in the next commits, so we can simplify
the logic and only check for user_info->mapped.account_name being NULL.
As it's the important factor that user_info->mapped.account_name is
non-NULL down in the auth stack.

fbf95a641b auth4: Remove unused auth_unix
auth_unix was in the source4/auth/ntlm for two reasons:
 - inherited from earlier Samba before the Samba4 fork
 - To support the ejs-backed SWAT (web administration tool)

Neither of these are good reasons to keep this unused code

plaintext PAM authentication in this part of the code in the
future.

6107c79c90 build: Do not build selftest binaries for builds without --enable-selftest
Add new for_selftest option to SAMBA_BINARY() and SAMBA3_BINARY()

This allows us to be much more consistent (at least in the core Samba)
and documents clearly why the binary should not be installed.

Not modified are
 - test_lp_load
 - notifyd-tests
 - gendrandperf
 - test* from examples/libsmbclient
 - dbwrap_torture
 - split_tokens
 - locktest2
 - msgtest
 - msg_sink
 - msg_source
 - versiontest
 - rpc_open_tcp
 - test_headers

As these are not tested in selftest so any change would also be
untested.  Of course they probably should be added in a different
MR.

Also not modified (because they are not tests, nor part of the
build system) are:
 - smb2mount
 - notifydd
 - log2pacp
 - debug2html
 - smbfilter
 - destroy_netlogon_creds_cli
 - spotlight2*
 - tevent_glib_tracker

These do however appear to be untested.

For now, the source4 forked client tools are left unchanged:
 - smbclient4
 - nmblookup4

Finally, the heimdal binaries are left as install=False as
they are either part of the build system or end-user tools
that we just don't want to install.  These are however tested.

The motivation is commit like c34ec003b7
and da87fa998a, which are both totally
correct but are not needed if the selftest is not run on MacOS.

There are likely other platforms or build environments where building
our test binaries is more pain than valuable, see for example also

Summary of the of the Query and Response from Microsoft on it's usage.

[REG:119013019612095] [MS-NRPC]: NETLOGON_LOGON_IDENTITY_INFO: Does
the Reserved field have LogonId meaning?

Questions:
  In NetrLogonSamLogonEx does the Reserved field
  (of NETLOGON_LOGON_IDENTITY_INFO) have LogonId meaning?

  What is a valid LogonID, and does have any audit usage?

  Samba is sending a constant "deadbeef" in hex and would like to
  understand any usage of this field.

Response:
  The NRPC spec is accurate in defining the field as Reserved, and without
  protocol significance. In the header file in our source code, it is
  defined as LogonId and commented as such, but it’s effectively not used.
  This is probably why the API structure has that field name. It may have
  been intended as such but it’s not used.

Samba will send a random value in this field.

899d00e6be s4-auth-tests: Fix test_kerberos with MIT krb
When a keytab of type MEMORY is used, the MIT kerberos krb5_kt_add_entry()
library function adds a keytab entry to the beginning of the keytab table,
instead of the end.

This adds a MIT kerberos conditional to reverse iterate through
the keytable entries to address this.

2fa2f132ae dsdb: Avoid calculating the PSO multiple times
In a typical user login query, the code tries to work out the PSO 2-3
times - once for the msDS-ResultantPSO attribute, and then again for the
msDS-User-Account-Control-Computed & msDS-UserPasswordExpiryTimeComputed
constructed attributes.

The PSO calculation is reasonably expensive, mostly due to the nested
groups calculation. If we've already constructed the msDS-ResultantPSO
attribute, then we can save ourselves extra work by just re-fetching the
result directly, rather than expanding the nested groups again from
scratch.

The previous patch improves efficiency when there are no PSOs in the
system. This should improve the case where there are PSOs that apply to
the users. (Unfortunately, it won't help where there are some PSOs in
the system, but no PSO applies to the user being queried).

Also updated sam.c so the msDS-ResultantPSO gets calculated first,
before the other constructed attributes.

442a38c918 dsdb/auth: Use PSO settings for lockOutThreshold/Duration
If a PSO applies to a user, use its lockOutThreshold/Duration settings
instead of the domain setting. When we lookup a user, we now include the
msDS-ResultantPSO attribute. If the attribute is present for a user,
then we lookup the corresponding PSO object to get the lockOutThreshold/
Duration settings.

Note: This is not quite enough to make the PSO lockout tests pass, as
msDS-User-Account-Control-Computed is still constructed based on the
domain lockoutDuration setting rather than the PSO.

Updating the password_hash.c code properly will be done in a subsequent
commit.

With the changes to make samba python code Py2/Py3 compatible there
now are many instances where string content is decoded.
Decoded string variables in Py2 are returned as the unicode type. Many
Py2 c-module functions that take string arguments only check for the
string type. However now it's quite possibe the content formally passed
as a string argument is now passed as unicode after being decoded,
such arguments are rejected and code can fail subtly. This only affects
places where the type is directly checked e.g. via PyStr_Check etc.
arguments that are parsed by ParseTuple* functions generally already
accept both string and unicode (if 's', 'z', 's*' format specifiers
are used)

7bf0308a31 s4:auth/gensec: let GENSEC_FEATURE_SESSION_KEY result in GSS_C_INTEG_FLAG
This is important to allow the 'new_spnego' with mech_list protection to work
for a SMB session setup.

This is not strictly needed as we always announce GENSEC_FEATURE_SESSION_KEY
in gensec_gssapi_have_feature(), but it's better to send GSS_C_INTEG_FLAG
over the wire.

This may prevent a ticket from a Samba client to an SMB server
(particularly a DC) being misused to connect to the LDAP server on that
DC, as the LDAP server will require GSSAPI signing of the connection.
