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.

This is not only a useful way to encode stuff, it also allows python
to handle the structures, and natrually allows them to be NDR encoded.

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.

I've examined the code paths involved, and it appears an alternative
fix has been made in the ldap_server/ldap_bind.c code, and there is no

As a server only try the mechs the client proposed

If the server doesn't support the first mech we pick the

By setting the event context to use for this operation (only) onto
the krb5_context just before we call that operation, we can try
and emulate the specification of an event context to the actual send_to_kdc()
This eliminates the specification of an event context to many other
cli_credentials calls, and the last use of event_context_find()
Special care is taken to restore the event context in the event of
nesting in the send_to_kdc function.
Andrew Bartlett
A new event context is constructed by LDB when required for secrets.ldb
This will be essentially unused, as LDB on TDB will only trigger 'fake'
events, and blocks on transactions and lock operations anyway.

when we are an RODC we need to be able to allow multiple auth backends

This makes the structure much more like NT_USER_TOKEN in the source3/
code. (The remaining changes are that privilages still need to be merged)
Andrew Bartlett
This also changes the primary group for anonymous to be the anonymous
SID, and adds code to detect and ignore this when constructing the token.
Andrew Bartlett
This also changes the calling convention slightly - we should always
allocate this with talloc_zero() to allow some elements to be
optional. Some elements may only make sense in Samba3, which I hope
will use this common structure.
Andrew Bartlett
This means that the core logic (but not the initialisation) of the
NTLMSSP server is in common, but uses different authentication backends.
Andrew Bartlett

This changes the talloc treatment of the session keys to avoid
memory duplication - the session key has always been allocated
onto the ntlmssp_context by the auth subsystem callback.
The remainder of the changes are cosmetics, such as avoiding
using lm_session_key as a pointer (and avoiding then doing an
if statement on something that is always true).
Andrew Bartlett
By re-adding this wrapper, the actual guts of these functions are now very
similar to that found in source3/libsmb/ntlmssp.c
This should make it easier to merge the implementations.
Andrew Bartlett
While it would save some CPU to only setup the session key when
requested (like windows does), this instead matches the
implementation in source3/libsmb/ntlmssp.c
We could re-add this later after the codebase is merged.
Andrew Bartlett
This does not change behaviour, and some of the whitespace isn't ideal, but
at the moment making this code more similar, even in cosmetics, will assist
later merge efforts.
Andrew Bartlett

Using "#!/usr/bin/env python" is more portable. It still isn't ideal

The common code does not have a mem_ctx on ntlmssp_check_packet() and
ntlmssp_unseal_packet().
We do however need some internal working of the code exposed, so some
structures are moved to ntlmssp_sign.h
Andrew Bartlett
The challenge here is that we are asked not to add the domain groups
again, but we need to search inside them for any aliases that we need
to add. So, we can't short-circuit the operation just because we found
the domain group.
Andrew Bartlett
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
This creates a new interface to the auth subsystem, to allow an
auth_context to be created from the ldb, and then tokenGroups to be
calculated in the same way that the auth subsystem would.
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
We perhaps need a more general API here, but for now extend the
credentials API to return the password last changed time that the
s3compat layer will need.
Andrew Bartlett
This allows for the rare case where the caller knows the target
principal. The check for lp_client_use_spnego_principal() is moved to
the spengo code to make this work.
Andrew Bartlett
This means that we consider the ccache only as reliable as the least
specified of the inputs we used.
This means that we will regenerate the ccache if any of the inputs change.
Andrew Bartlett
the talloc python interface for tp_alloc and tp_dealloc relies on a
cast to a py_talloc_Object to find the talloc_ctx (see
py_talloc_dealloc). This means we rely on the talloc_ctx for the
object being directly after the PyObject_HEAD
This fixes the talloc free with references bug in samba_dnsupdate
The actual problem was the tp_alloc() call in
PyCredentialCacheContainer_from_ccache_container() which used a cast
from a py_talloc_Object to a PyCredentialCacheContainerObject. That
case effectively changed the parent/child relationship between the
talloc_ctx and the ccc ptr.
This patch changes all the structures that follow this pattern to put
the TALLOC_CTX directly after the PyObject_HEAD, to ensure that if
anyone else decides to do a dangerous cast like this that it won't
cause the same sort of subtle breakage.
Pair-Programmed-With: Rusty Russell <rusty@samba.org>
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.
