Changes all over the shop, but all towards:
- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to
merge the 'client' and 'server' functions, so they both operate on a
single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of
data structures...

get Win2k to send a valid signiture in it's session setup reply - which it will
give to win2k clients.
So, I need to look at becoming 'more like MS', but for now I'll get this code
into the tree. It's actually based on the TNG cli_pipe_ntlmssp.c, as it was
slightly easier to understand than our own (but only the utility functions
remain in any way intact...).
This includes the mysical 'NTLM2' code - I have no idea if it actually works.
(I couldn't get TNG to use it for its pipes either).

relitivly useful external lib from this code, and to remove the dupicate
NTLMSSP code elsewhere in samba (RPC pipes, LDAP client).
The code I've replaced this with in cliconnect.c is relitivly ugly, and
I hope to replace it with a more general SPENGO layer at some later date.

of the SWAT code, and adding a base64 encoder.
The main purpose of this patch is to add NTLMSSP support to 'ntlm_auth', for
use with Squid. Unfortunetly the squid side doesn't quite support what we need
yet.
Changes to winbind to get us the info we need, and a couple of consequential
changes/cleanups in the rest of the code.

eliminate the dependency on the auth subsystem. The next step is to add
the required code to 'ntlm_auth', for export to Squid etc.

This tries to extract our server-side code out of sessetup.c, and into a more
general lib. I hope this is only a temporay resting place - I indend to
refactor it again into an auth-subsystem independent lib, using callbacks.
Move some of our our NTLMSSP #defines into a new file, and add two that I found
in the COMsource docs - we seem to have a double-up, but I've verified from
traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real.
This code also copes with ASCII clients - not that we will ever see any here,
but I hope to use this for HTTP, were we can get them. Win2k authenticates
fine under forced ASCII, btw.
Tested with Win2k, NTLMv2 and Samba's smbclient.
