1. using smbc_getxattr() et al, one may now request all access control
entities in the ACL without getting all other NT attributes.
2. added the ability to exclude specified attributes from the result set
provided by smbc_getxattr() et al, when requesting all attributes,
all NT attributes, or all DOS attributes.
3. eliminated all compiler warnings, including when --enable-developer
compiler flags are in use. removed -Wcast-qual flag from list, as that
is specifically to force warnings in the case of casting away qualifiers.
Note: In the process of eliminating compiler warnings, a few nasties were
discovered. In the file libads/sasl.c, PRIVATE kerberos interfaces
are being used; and in libsmb/clikrb5.c, both PRIAVE and DEPRECATED
kerberos interfaces are being used. Someone who knows kerberos
should look at these and determine if there is an alternate method
of accomplishing the task.

This patch re-adds support for 'optional' SMB signing. It also ensures that
we are much more careful about when we enable signing, particularly with
on-the-fly smb.conf reloads.
The client code will now attempt to use smb signing by default, and disable
it if the server doesn't correctly support it.

register_vuid correctly. We ended up with the local netbios name in
substitutions for %D later.

P.S: Tridge, I can *really* see why you want to get rid of global variables

additional parameter.
Jerry: This is a change in behaviour, but I think it is necessary.

- 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...
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,

from RFC but I'm smelling a client bug here.
/* only look at the first OID for determining the mechToken --
accoirding to RFC2478, we should choose the one we want

Problem observed when connecting to a member (samba box)
of an AD domain as a user in a Samba domain. Samba member
server sent back krb5/mskrb5/ntlmssp as mechtypes, but the
client (2ksp3) replied with ntlmssp/mskrb5/krb5 and an
NTLMSSP mechtoken. --jerry */
to pstr_sprintf() and fstr_sprintf() to try to standardize.
lots of snprintf() calls were using len-1; some were using
len. At least this helps to be consistent.
I think (my changes haven't affected this I believe). Initial support on the
server side for smbclient. Still doesn't work for w2k clients I think...
Work in progress..... (don't change).
Jeremy.
