We should treat most gensec related structures private.
It's a long way, but this is a start.

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).

This allows a password alone to be used to accept kerberos tickets.
Of course, we need to have got the salt right, but we do not need also
the correct kvno. This allows gensec_gssapi to accept tickets based on
a secrets.tdb entry.

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.

Several functions use the same logic as kerberos_pac_logon_info. Move
kerberos_pac_logon_info to common code and reuse it to remove the code

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 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
check everywhere.

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.

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.

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.
