the idea is to have a directory service db layer
which will be used by the ldap server, samr server, drsuapi server
authentification...
I plan to make different implementations of this interface possible
- current default will be the current samdb code with sam.ldb
- a compat implementation for samba3 (if someone wants to write one)
- a new dsdb implementation which:
- understands naming contexts (directory parrtitions)
- do schema and acl checking checking
- maintain objectGUID, timestamps and USN number,
maybe linked attributes ('member' and 'memberOf' attributes)
- store metadata on a attribute=value combination...

lm hash from the samdb, and thus not checking the verifier)
fixed the client side to calculate the lm verifier based on the nt
hash, not the lm hash (confirmed using w2k3)

verify that the security descriptor found in the SamSync is the same
as what is available over SAMR.
Unfortunately, the administrator seems unable to retrieve the SACL on
the security descriptor, so I've added a new function to compare with
a mask.

This compares values for the domain and for secrets. We still have
some problems we need to sort out for secrets.
Also rename a number of structures in samr.idl and netlogon.idl, to
better express their consistancy.

NETLOGON.
In particular, rename samr_Name to samr_String - given that many
strings in this pipe are not 'names', the previous was just confusing.
(I look forward to PIDL turning these into simple char * some day...).
Also export out a few changes from testjoin.c to allow for how I have
written the new RPC-SAMSYNC test.

- tidied up some of the system includes
- moved a few more structures back from misc.idl to netlogon.idl and samr.idl now that pidl
knows about inter-IDL dependencies
(This used to be commit 7b7477ac42)
The thing that finally convinced me that minimal includes was worth
pursuing for rpc was a compiler (tcc) that failed to build Samba due
to reaching internal limits of the size of include files. Also the
fact that includes.h.gch was 16MB, which really seems excessive. This
patch brings it back to 12M, which is still too large, but
better. Note that this patch speeds up compile times for both the pch
and non-pch case.
This change also includes the addition iof a "depends()" option in our
IDL files, allowing you to specify that one IDL file depends on
another. This capability was needed for the auto-includes generation.

caller doesn't have to worry about the constraint of only opening a
database a single time in a process. These wrappers will ensure that
only a single open is done, and will auto-close when the last instance
is gone.
When you are finished with a database pointer, use talloc_free() to
close it.
note that this code does not take account of the threads process
model, and does not yet take account of symlinks or hard links to tdb
files.

so talloc now doesn't contain any ldb specific functions.
allow NULL to be passed to a couple more talloc() functions
(This used to be commit 1246f80d80)
void *talloc_reference(const void *context, const void *ptr);
this function makes a secondary reference to ptr, and hangs it off the
given context. This greatly simplifies some of the current reference
counting code in the samr server and I suspect it will be widely used
in other places too.
the way you use it is like this:
domain_state->connect_state = talloc_reference(domain_state, connect_state);
that makes the element connect_state of domain_state a secondary
reference to connect_state. The connect_state structure will then only
be freed when both domain_state and the original connect_state go
away, allowing you to free them independently and in any order.
you could do this alrady using a talloc destructor, and that is what
the samr server did previously, but that meant this construct was
being reinvented in several places. So this convenience function sets
up the destructor for you, giving a much more convenient and less
error prone API.
(This used to be commit dc53150861)
have the handle type implied by the parameter name. There are four
types of handle: connect, domain, user and group handles. The
various samr_Connect functions return a connect handle, and the
samr_OpenFoo functions return a foo handle.
There is one exception - the samr_{Get,Set}Security function can
take any type of handle.
Fix up all C callers.

Fix kerberos session key issues - we need to call the
routine for extracting the session key, not just read the cache.

count features of talloc, instead of re-implementing both those
features inside of samdb (which is what we did before).
This makes samdb considerably simpler, and also fixes some bugs, as I
found some error paths that didn't call samdb_close(). Those are now
handled by the fact that a talloc_free() will auto-close and destroy
the samdb context, using a destructor.
(This used to be commit da60987a92)
This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().

This implements gensec for Samba's server side, and brings gensec up
to the standards of a full subsystem.
This means that use of the subsystem is by gensec_* functions, not
function pointers in structures (this is internal). This causes
changes in all the existing gensec users.
Our RPC server no longer contains it's own generalised security
scheme, and now calls gensec directly.
Gensec has also taken over the role of auth/auth_ntlmssp.c
An important part of gensec, is the output of the 'session_info'
struct. This is now reference counted, so that we can correctly free
it when a pipe is closed, no matter if it was inherited, or created by
per-pipe authentication.
The schannel code is reworked, to be in the same file for client and
server.
ntlm_auth is reworked to use gensec.
The major problem with this code is the way it relies on subsystem
auto-initialisation. The primary reason for this commit now.is to
allow these problems to be looked at, and fixed.
There are problems with the new code:
- I've tested it with smbtorture, but currently don't have VMware and
valgrind working (this I'll fix soon).
- The SPNEGO code is client-only at this point.
- We still do not do kerberos.

names rather than our crazy naming scheme. So DES is now called
des_crypt() rather than smbhash()
- added the code from the solution of the ADS crypto challenge that
allows Samba to correctly handle a 128 bit session key in all of the
netr_ServerAuthenticateX() varients. A huge thanks to Luke Howard
from PADL for solving this one!
- restructured the server side rpc authentication to allow for other
than NTLMSSP sign and seal. This commit just adds the structure, the
next commit will add schannel server side support.
- added 128 bit session key support to our client side code, and
testing against w2k3 with smbtorture. Works well.
