The previous API was not clear as to who owned the returned session key.
This fixes a valgrind-found use-after-free in the NTLMSSP key derivation code,
and avoids making allocations - we steal and zero instead.

with the latest bind9 nsupdate, we need to be able to control if the
ticket we use is forwardable

when we are an RODC we need to be able to allow multiple auth backends
to process a single auth request. First the sam backend will try to
authenticate, using locally stored passwords. If this backend can't
find local passwords then it will try the winbind backend and
authenticate via a writeable DC

when an RODC tries to authenticate against an account and the account
has no password information it needs to send a message to the drepl
server to tell it to try and replicate the secret information from
a writeable DC

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.

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

Using "#!/usr/bin/env python" is more portable. It still isn't ideal
though, as we should really use the python path found at configure
time. We do that in many places already, but some don't.
