GENSEC, and to pull SCHANNEL into GENSEC, by making it less 'special'.
GENSEC now no longer has it's own handling of 'set username' etc,
instead it uses cli_credentials calls.
In order to link the credentails code right though Samba, a lot of
interfaces have changed to remove 'username, domain, password'
arguments, and these have been replaced with a single 'struct
cli_credentials'.
In the session setup code, a new parameter 'workgroup' contains the
client/server current workgroup, which seems unrelated to the
authentication exchange (it was being filled in from the auth info).
This allows in particular kerberos to only call back for passwords
when it actually needs to perform the kinit.
The kerberos code has been modified not to use the SPNEGO provided
'principal name' (in the mechListMIC), but to instead use the name the
host was connected to as. This better matches Microsoft behaviour,
is more secure and allows better use of standard kerberos functions.
To achieve this, I made changes to our socket code so that the
hostname (before name resolution) is now recorded on the socket.
In schannel, most of the code from librpc/rpc/dcerpc_schannel.c is now
in libcli/auth/schannel.c, and it looks much more like a standard
GENSEC module. The actual sign/seal code moved to
libcli/auth/schannel_sign.c in a previous commit.
The schannel credentails structure is now merged with the rest of the
credentails, as many of the values (username, workstation, domain)
where already present there. This makes handling this in a generic
manner much easier, as there is no longer a custom entry-point.
The auth_domain module continues to be developed, but is now just as
functional as auth_winbind. The changes here are consequential to the
schannel changes.
The only removed function at this point is the RPC-LOGIN test
(simulating the load of a WinXP login), which needs much more work to
clean it up (it contains copies of too much code from all over the
torture suite, and I havn't been able to penetrate its 'structure').

I wanted to add a simple 'workstation' argument to the DCERPC
authenticated binding calls, but this patch kind of grew from there.
With SCHANNEL, the 'workstation' name (the netbios name of the client)
matters, as this is what ties the session between the NETLOGON ops and
the SCHANNEL bind. This changes a lot of files, and these will again
be changed when jelmer does the credentials work.
I also correct some schannel IDL to distinguish between workstation
names and account names. The distinction matters for domain trust
accounts.
Issues in handling this (issues with lifetime of talloc pointers)
caused me to change the 'creds_CredentialsState' and 'struct
dcerpc_binding' pointers to always be talloc()ed pointers.
In the schannel DB, we now store both the domain and computername, and
query on both. This should ensure we fault correctly when the domain
is specified incorrectly in the SCHANNEL bind.
In the RPC-SCHANNEL test, I finally fixed a bug that vl pointed out,
where the comment claimed we re-used a connection, but in fact we made
a new connection.
This was achived by breaking apart some of the
dcerpc_secondary_connection() logic.
The addition of workstation handling was also propogated to NTLMSSP
and GENSEC, for completeness.
The RPC-SAMSYNC test has been cleaned up a little, using a loop over
usernames/passwords rather than manually expanded tests. This will be
expanded further (the code in #if 0 in this patch) to use a newly
created user account for testing.
In making this test pass test_rpc.sh, I found a bug in the RPC-ECHO
server, caused by the removal of [ref] and the assoicated pointer from
the IDL. This has been re-added, until the underlying pidl issues are
solved.

In developing a GSSAPI plugin for GENSEC, it became clear that the API
needed to change:
- GSSAPI exposes only a wrap() and unwrap() interface, and determines
the location of the signature itself.
- The 'have feature' API did not correctly function in the recursive
SPNEGO environment.
As such, NTLMSSP has been updated to support these methods.
The LDAP client and server have been updated to use the new wrap() and
unwrap() methods, and now pass the LDAP-* tests in our smbtorture.
(Unfortunely I still get valgrind warnings, in the code that was
previously unreachable).

- Update Samba4's kerberos code to match the 'salting' changes in
Samba3 (and many other cleanups by jra).
- Move GENSEC into the modern era of talloc destructors. This avoids
many of the memory leaks in this code, as we now can't somehow
'forget' to call the end routine.
- This required fixing some of the talloc hierarchies.
- The new krb5 seems more sensitive to getting the service name
right, so start actually setting the service name on the krb5 context.

Break out the samsync tests from RPC-NETLOGON into a new RPC-SAMSYNC,
that will cross-verify all the values.
Add support for the way netlogon credentials are shared between the
pipe that sets up schannel and the pipe that is encrypted with it.
Test this support, by calling both NETLOGON and SAMR operations in the
RPC-SCHANNEL test.
Move some of the Netlogon NEG flags into the .idl, now we have an idea
what a few of them really are.
Rename the sam_pwd_hash into a name that has meaning (all other crypto
functions were renamed in Samba4 ages ago).
Break out NTLMv2 functionality for operation on the NT hash - I intend
to do NTLMv2 logins in the samsync test in future, and naturally I
only have the hash.

by making our gensec structures a talloc child of the open connection
we can be sure that it will be destroyed when the connection is
dropped.

This means that 'require NTLMv2 session security' now works for RPC
pipe signing. We don't yet have sealing, but it can't be much further.
This is almost all tridge's code, munged into a form that can work
with the GENSEC API.
This commit also includes more lsakey fixes - that key is used for all
DCE-RPC level authenticated connections, even over CIFS/ncacn_np.
No doubt I missed something, but I'm going to get some sleep :-)

The bug (found by tridge) is that Win2k3 is being tighter about the
NTLMSSP flags. If we don't negotiate sealing, we can't use it.
We now have a way to indicate to the GENSEC implementation mechanisms
what things we want for a connection.

- We can now connect to hosts that follow the SPNEGO RFC, and *do not*
give us their principal name in the mechListMIC.
- The client code now remembers the hostname it connects to
- We now kinit for a user, if there is not valid ticket already
- Re-introduce clock skew compensation
TODO:
- See if the username in the ccache matches the username specified
- Use a private ccache, rather then the global one, for a 'new' kinit
- Determine 'default' usernames.
- The default for Krb5 is the one in the ccache, then $USER
- For NTLMSSP, it's just $USER

- Add the concept of a 'subcontext' into gensec, so that the spengo
code doesn't have to figure out how to make one.
(A subcontext inherits the username, domain, password (or callback)
from the main context).
- Add comments to some other routines, and explain a bit about what
the various 'start' functions are for.

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.

This layer is used for DCERPC security, as well as ntlm_auth at this
time. It expect things like SASL and the CIFS layer to use it as
well.
The particular purpose of this layer is to introduce SPENGO, which
needs generic access to the actual implementation mechanisms.
Schannel, due to it's 'interesting' setup properties is in GENSEC, but
is only in the RPC code.
