haven't broken krb5 ticket verification in the mainline code path,
also need to check with valgrind. Everything now compiles (MIT, need
to also check Heimdal) and the "net keytab" utility code will follow.

but security=ADS, we would attempt to free the principal name that krb5
never allocated.
Also fix the dump_data() of the session key, now that we use a data_blob to
store that.

- 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...

keytab support code, but it won't be enabled until we add that to smb.conf.

Please hammer on this...

Currently I'm compiling against MIT Kerberos 1.2.8.
Anthony, you said you have a heimdal installation available. Could you
please compile this stuff with krb and check it with valgrind?
Thanks,
Volker

it's a different rc than KRB5_BAD_ENCTYPE (which exists on both MIT and
Heimdal). This will just make the debug show up at level 3 always.
Jeremy, you may want to revisit this, but it's probably not worth the hassle.

Server code *should* also work (I'll check shortly). May be the odd memory
leak. Problem was we (a) weren't setting signing on in the client krb5 sessionsetup
code (b) we need to ask for a subkey... (c). The client and server need to
ask for local and remote subkeys respectively.
Thanks to Paul Nelson @ Thursby for some sage advice on this :-).

This allows us to join as a BDC, without appearing on the network as one
until we have the database replicated, and the admin changes the configuration.
This also change the SID retreval order from secrets.tdb, so we no longer
require a 'net rpc getsid' - the sid fetch during the domain join is sufficient.
Also minor fixes to 'net'.

Now smbclient, net, and swat use their own proto files - now the global
proto.h
The change to libads/kerberos.c was to break up the dependency on secrets.c -
we want to be able to write an ADS client that doesn't need local secrets.
I have other breakups in the works - I will remove the dependency of
rpc_parse on passdb (and therefore secrets.c) shortly.
(NOTE: This patch does *not* break up includes.h, or other such forbidden
actions).
