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).

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.
This changes auth_session_info_transport to just be a wrapper, rather
than a copy that has to be kept in sync.
As auth_session_info was already wrapped in python, this required
changes to the existing pyauth wrapper and it's users.

This changes the structure being used to convey the current user state
from the netlogon-derived 'netr_SamInfo3' structure to a purpose-built
structure that matches the internals of the Samba auth subsystem and
contains the final group list, as well as the final privilege set and
session key.
These previously had to be re-created on the server side of the pipe
each time.

This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc. This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.
The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.
Andrew Barltett
This makes everything reference a server_info->sids list, which is now
a struct dom_sid *, not a struct dom_sid **. This is in keeping with
the other sid lists in the security_token etc.
In the process, I also tidy up the talloc tree (move more structures
under their logical parents) and check for some possible overflows in
situations with a pathological number of sids.
Andrew Bartlett
This will be a building block for a tokenGroups test, which can
compare against a remote server (in particular the rootDSE) against
what we would calculate the tokenGroups to be.
(this meant moving some parts out of the auth_sam code into the
containing library)
Andrew Bartlett
This isn't quite as good as using tokenGroups, but that is only
available for BASE searches, and this isn't how the all the callers
work at the moment.
Andrew Bartlett
Even if we can't calculate the local groups (because we don't have a
local SAM to do it with) we still need to include the domain groups in
the session_info token.

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

This allows us to control what groups should be added in what use
cases, and in particular to more carefully control the introduction of
the 'authenticated' group.
In particular, in the 'service_named_pipe' protocol, we do not have
control over the addition of the authenticated users group, so we key
of 'is this user the anonymous SID'.
This also takes more care to allocate the right length ptoken->sids
Andrew Bartlett
The group list in the PAC does not include 'enterprise DCs' and
BUILTIN groups, so we should generate it on each server, not in the
list we pass around in the PAC or SamLogon reply.
Andrew Bartlett
The auth context was in the past only for NTLM authentication, but we
need a SAM, an event context and and loadparm context for calculating
the local groups too, so re-use that infrustructure we already have in
place.
However, to avoid problems where we may not have an auth_context (in
torture tests, for example), allow a simpler 'session_info' to be
generated, by passing this via an indirection in gensec and an
generate_session_info() function pointer in the struct auth_context.
In the smb_server (for old-style session setups) we need to change the
async context to a new 'struct sesssetup_context'. This allows us to
use the auth_context in processing the authentication reply .
Andrew Bartlett
This should always return a simple structure with no need to consult a
DB, so remove the event context, and simplfy to call helper functions
that don't look at privilages.
Andrew Bartlett
This uses Heimdal's PAC parsing code in the:
- LOCAL-PAC test
- gensec_gssapi server
- KDC (where is was already used, the support code refactored from here)
In addition, the service and KDC checksums are recorded in the struct
auth_serversupplied_info, allowing them to be extracted for validation
across NETLOGON.
