This change moves the addition of "Authenticated Users" from the very end of the
token processing to the start. The reason is that we need to see if
"Authenticated Users" is a member of other builtin groups, just as we
would for any other SID. This picks up the "Pre-Windows 2000 Compatible Access"
group, which is in turn often used in ACLs on LDAP objects.
Without this change, the eventual token does not contain S-1-5-32-554
and users other than "Administrator" are unable to read uidNumber
(in particular).

If we create a copy of the credential state we miss updates to the
credentials.
To establish a netlogon schannel connection we create client credentials
and authenticate with them using
dcerpc_netr_ServerAuthenticate2()
For this we call netlogon_creds_client_authenticator() which increases
the sequence number and steps the credentials. Lets assume the sequence
number is 1002.
After a successful authentication we get the server credentials and we
send bind a auth request with the received creds. This sets up gensec
and the gensec schannel module created a copy of the client creds and
stores it in the schannel auth state. So the creds stored in gensec have
the sequence number 1002.
After that we continue and need the client credentials to call
dcerpc_netr_LogonGetCapabilities()
to verify the connection. So we need to increase the sequence number of
the credentials to 1004 and step the credentials to the next state. The
server always does the same and everything is just fine here.
The connection is established and we want to do another netlogon call.
So we get the creds from gensec and want to do a netlogon call e.g.
dcerpc_netr_SamLogonWithFlags.
We get the needed creds from gensec. The sequence number is 1002 and
we talk to the server. The server is already ahead cause we are already
at sequence number 1004 and the server expects it to be 1006. So the
server gives us ACCESS_DENIED cause we use a copy in gensec.

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.

This will allow us to detect from the smb.conf if this is a Samba4 AD
DC which will allow smarter handling of (for example) accidentially
starting smbd rather than samba.
To cope with upgrades from existing Samba4 installs, 'domain
controller' is a synonym of 'active directory domain controller' and
new parameters 'classic primary domain controller' and 'classic backup
domain controller' are added.

To remove finddcs_nbt these missing deps need to be added. These
subsystems linked to to implicit dependencies provided by finddcs.
Due to the new arrangmenet of subsystems, MESSAGING needs to be a
private library to avoid being a source of duplicate symbols.
Andrew Bartlett
This is also where the related krb5_princ_component is declared.
Also fix the configure check to use the correct name
This helps the autoconf build on Heimdal.
Andrew Bartlett
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.
We need to ifdef out some minor things here because there is no available API
to set these options in MIT.
The realm and canonicalize options should be not interesting in the client
case. Same for the send_to_kdc hacks.
Also the OLD DES3 enctype is not at all interesting. I am not aware that
Windows will ever use DES3 and no modern implementation relies on that enctype
anymore as it has been fully deprecated long ago, so we can simply ignore it.
Thanks to Wolfgang Sourdeau for reporting this.

For now let's just loose this functionality with the MIT build.
gss_import/export_cred should be availa ble when MIT 1.11 is released and this
code is used only in some proxy scenario. Not normally needed for common
configurations.
Unfortunately these functions are not available in MIT and there is no easy
workaround or compat funciton I can see at this stage. Will fix properly once
MIT gets the necessary functions or if another workaround can be found.
Make it clearly a gensec_krb5 accessory file.
This function should never be used anywhere else.
This function was copied out from the Heimdal tree and is kept in a separate
file for clarity and to keep the original license boilerplate.
This makes it simpler to slowly integrate MIT support and also amkes it
somewhat clearer what operation is really requested.
The 24u2 part is really only used by the cifs proxy code so we can temporarily
disable it in the MIT build w/o major consequences.
With waf build include directories are defined by dependencies specified to subsystems.
Without proper dependency <gssapi/gssapi.h> cannot be found for embedded Heimdal builds
when there are no system-wide gssapi/gssapi.h available.
Split out GSSAPI header includes in a separate replacement header and use that explicitly
where needed.

This avoids casting to and from the struct auth_user_info_dc *user_info_dc
to to this, the
if (user_info_dc->info->authenticated)

function that gensec_security->auth_context->generate_session_info
points to.
Andrew Bartlett
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.
Andrew Bartlett
These are optional to supply - some callers only provide an auth_context for the
other plugin functions, and so we need to deal with this cleanly.

This makes the dependencies simpler, as this code path is no longer
required. (That is, it makes no sense to have an NTLM login without
an auth context, and the gensec_gssapi and gensec_krb5 modules call
the PAC blob function below instead).
Andrew Bartlett
This demonstrates how a different function pointer can be supplied
to handle the PAC blob, without depending on the provisioned samdb etc.
Andrew Bartlett
This uses a single callback to handle the PAC from the DATA_BLOB
format until it becomes a struct auth_session_info.
This allows a seperation between the GSS acceptor code and the PAC
interpretation code based on the supplied auth context.

This library was tiny - containing just two public functions than were
themselves trivial. The amount of overhead this causes isn't really worth the
benefits of sharing the code with other projects like OpenChange. In addition, this code
isn't really generically useful anyway, as it can only load from the module path
set for Samba at configure time.
Adding a new library was breaking the API/ABI anyway, so OpenChange had to be
updated to cope with the new situation one way or another. I've added a simpler
(compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.

This will allow gensec_start.c to move to the top level. This does not change
what code uses the cli_credentials code, but allows the gensec code to be
more broadly.
Andrew Bartlett
This is done so that the lpcfg_ functions are available across the whole
build, either with the struct loadparm_context loaded from an smb.conf directly
or as a wrapper around the source3 param code.
This is not the final, merged loadparm, but simply one step to make
it easier to solve other problems while we make our slow progress
on this difficult problem.
Andrew Bartlett
to properly support multi-domain forests we need to determine if an
incoming username is part of a known forest domain or not. To do this
for all possible SPN forms, we need to use CrackNames.
This changes map_user_info() to use CrackNames if a SAM context is
available, and asks the CrackNames services to parse the incoming
username and domain into a NT4 form, which can then be used in the
SAM.
