by saving the UNIX token used to set a delete on close flag,
and using it when doing the delete. libsmbsharemodes.so still
needs updating to cope with this change.

Don't count open pipes in the num_files_open on a connection.
conn_idle_all() handles this by looking for open rpc handles
If there are no open handles, we can close the IPC$ share.

Make the corresponding messages a debug level 3, not 0 to not flood log.smbd.

- 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...
There is a workaround documented in the bug report.
This patch does:
* add server support for the LSA_DS UUID on the lsarpc pipe
* store a list of context_ids/api_structs in the pipe_struct
so that we don't have to lookup the function table for a pipe.
We just match the context_id. Note that a dce/rpc alter_context
does not destroy the previous context so it is possible to
have multiple bindings active on the same pipe. Observed from
standalone win2k sp4 client.
* added server code for DsROleGetPrimaryDOmainInfo() but disabled it
since it causes problems enumerating users and groups from a 2ksp4
domain member in a Samba domain.
This time its the pdb_getsampwuid() function - which was only being used by the
SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is
actually generated at login time, and the other changes here simply move that
data around.
This also means that (when I check some details) we will be able to use the
user session key, even when we are not actually the DC, becouse its one of the
components of the info3 struct returned on logon.

degree of seperation betwen reading/writing the raw NamedPipe SMB packets
and the matching operations inside smbd's RPC components.
This patch is designed for no change in behaviour, and my tests hold that to be
true. This patch does however allow for the future loadable modules interface
to specify function pointers in replacement of the fixed state.
The pipes_struct has been split into two peices, with smb_np_struct taking the
information that should be generic to where the data ends up.
Some other minor changes are made: we get another small helper function in
util_sock.c and some of the original code has better failure debugs and
variable use. (As per on-list comments).
