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.

- added workstation to auth_session_info in rpc servers
- added session key fetch hook in crypto backends in dcesrv
- store and fetch seed as well as a session key in schannel ldb
- when a client uses schannel to setup a netlogon pipe connection we
also need to setup the credentials from the schannel negotiation so
credentials chaining works
- added server side netr_LogonGetDomainInfo() call

- added server side support for schannel type 23. This allows WinXP to establish a schannel connection
to Samba4 as an ADS DC
- added client side support for schannel type 23, but disabled it as currently the client
code has now way of getting the fully qualified domain name (which is needed)
- report dcerpc faults in the server code in the log

pwd -> password
passwd -> password
username -> account_name
Also work on consistant structure feild names between these two pipes,
and fix up some callers to use samr_Password for the netlogon
credential code.

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.

Samba's NTLMSSP code is now fully talloc based, which should go a long
way to cleaning up the memory leaks in this code. This also avoids a
lot of extra copies of data, as we now allocate the 'return' blobs on
a caller-supplied context.
I have also been doing a lot of work towards NTLM2 signing and
sealing. I have this working for sealing, but not for the verifier
(MD5 integrity check on the stream) which is still incorrect.
(I can aim a rpcecho sinkdata from a Win2k3 box to my server, and the
data arrives intact, but the signature check fails. It does however
match the test values I have...).
The new torture test is cludged in - when we get a unit test suite
back, I'll happliy put it in the 'right' place....

- auto-add the computer objectclass for computer accounts on create
- added two types of password change call in samr server
- reset last_fault_code before each dcerpc call

- This required using NETLOGON_NEG_AUTH2_FLAGS for the
SetupCredentials2 negotiation flags, which is what Samba3 does,
because otherwise the server uses different crypto.
- This tests the returned session keys, which we decrypt.
- Update the Samba4 notion of a 'session key' to be a DATA_BLOB in
most places.
- Fix session key code to return NT_STATUS_NO_SESSION_KEY if none is
available.
- Remove a useless argument to SMBsesskeygen_ntv1
- move netr_CredentialState from the .idl to the new credentials.h

use NTLMSSP sign or seal at the RPC layer
It doesn't work yet, but then again neither does the old code (which
just assumed the SMB session key was used, which of course makes no
sense on a ncacn_ip_tcp connection)

request (a dead socket). I discovered this when testing against Sun's
PC-NetLink.
cleaned up the naming of some of the samr requests
add IDL and test code for samr_QueryGroupMember(),
samr_SetMemberAttributesOfGroup() and samr_Shutdown(). (actually, I
didn't leave the samr_Shutdown() test in, as its fatal to windows
servers due to doing exactly what it says it does).

- implement lsa_LookupNames, lsa_LookupSids and lsa_Close
- add stubs for remaining functions from idl
- fix lsa_OpenPolicy and lsa_OpenPolicy2 to use a temporary
talloc context for the rpc call

added ldbedit, a _really_ useful command
added ldbadd, ldbdel, ldbsearch and ldbmodify to build
solved lots of timezone issues, we now pass the torture tests with
client and server in different zones
fixed several build issues
I know this breaks the no-LDAP build. Wait till I arrive in San Jose for that
fix.

- added schannel sign and sign/seal support to the dcerpc client
code. You select it with binding options of "schannel,sign" or
"schannel,seal".

e.g.
ncacn_np:myserver:[samr,sign,print]
will now enable the packet debugging
and the debugging is not bound anymore to the debuglevel >= 2
in the torture tests
- also the dcesrv_remote module now supports debugging of the packets
use the 'dcerpc_remote:binding' smb.conf parameter.

handles are not shared between open dcerpc connections, even when
those connections are on the same SMB socket. I have tested this with
w2k3, w2k and NT4. It seems that policy handles have a strict scope of
the dcerpc connection on which they were opened.
I realise that this goes against existing folk-law in the team, but it
seems that the previous testing (I'm not sure who did this?) was
wrong. Perhaps clients do send us policy handles from other
connections, but if they do then the correct thing to do is to fail
the operation with a dcerpc fault. I suspect that failing it with
exactly the right dcerpc fault code is important.

This adds support for bigendian rpc in the client. I have installed
SUN pcnetlink locally and am using it to test the samba4 rpc
code. This allows us to easily find places where we have stuffed up
the types (such as 2 uint16 versus a uint32), as testing both
big-endian and little-endian easily shows which is correct. I have now
used this to fix several bugs like that in the samba4 IDL.
In order to make this work I also had to redefine a GUID as a true
structure, not a blob. From the pcnetlink wire it is clear that it is
indeed defined as a structure (the byte order changes). This required
changing lots of Samba code to use a GUID as a structure.
I also had to fix the if_version code in dcerpc syntax IDs, as it
turns out they are a single uint32 not two uint16s.
The big-endian support is a bit ugly at the moment, and breaks the
layering in some places. More work is needed, especially on the server
side.

implements the epm_Lookup() call, I'll add the other important calls
soon. I was rather pleased to find that epm_Lookup() worked first
time, which is particularly surprising given its complexity.
This required quite a bit of new infrastructure:
* a generic way of handling dcerpc policy handles in the rpc server
* added type checked varients of talloc. These are much less error
prone. I'd like to move to using these for nearly all uses of
talloc.
* added more dcerpc fault handling code, and translation from
NTSTATUS to a dcerpc fault code
* added data_blob_talloc_zero() for allocating an initially zero
blob
* added a endpoint enumeration hook in the dcerpc endpoint server
operations
