This should make it easier to port rpcclient code across to net.
It also allows SPNEGO (the NTLMSSP subsystem in particular) to work, becouse
it kills off the early destruction of the clear-text password.

subystem.
The particular aim is to modularized the interface - so that we
can have arbitrary password back-ends.
This code adds one such back-end, a 'winbind' module to authenticate
against the winbind_auth_crap functionality. While fully-functional
this code is mainly useful as a demonstration, because we don't get
back the info3 as we would for direct ntdomain authentication.
This commit introduced the new 'auth methods' parameter, in the
spirit of the 'auth order' discussed on the lists. It is renamed
because not all the methods may be consulted, even if previous
methods fail - they may not have a suitable challenge for example.
Also, we have a 'local' authentication method, for old-style
'unix if plaintext, sam if encrypted' authentication and a
'guest' module to handle guest logins in a single place.
While this current design is not ideal, I feel that it does
provide a better infrastructure than the current design, and can
be built upon.
The following parameters have changed:
- use rhosts =
This has been replaced by the 'rhosts' authentication method,
and can be specified like 'auth methods = guest rhosts'
- hosts equiv =
This needs both this parameter and an 'auth methods' entry
to be effective. (auth methods = guest hostsequiv ....)
- plaintext to smbpasswd =
This is replaced by specifying 'sam' rather than 'local'
in the auth methods.
The security = parameter is unchanged, and now provides defaults
for the 'auth methods' parameter.
The available auth methods are:
guest
rhosts
hostsequiv
sam (passdb direct hash access)
unix (PAM, crypt() etc)
local (the combination of the above, based on encryption)
smbserver (old security=server)
ntdomain (old security=domain)
winbind (use winbind to cache DC connections)
Assistance in testing, or the production of new and interesting
authentication modules is always appreciated.

Subject: [patch]: makes some arrays const to be shared between processes
Hi!
This patch makes some arrays const. So these arrays go to text/rodata
segment and are shared between all of the processes which use shared
library with these arrays.
Regards,
Andrew V. Samoilov.
P.S. Please cc your answer to kai@cmail.ru,
I don't subscribed to this list.
ChangeLog:
* cliconnect.c (prots): Make const.
* clierror.c (rap_errmap): Likewise.
* nmblib.c (nmb_header_opcode_names): Likewise.
(lookup_opcode_name): Make opcode_namep const. Eliminate i.
* nterr.c (nt_err_code_struct): Typedef const.
* smberr.c (err_code_struct): Make const.
(err_classes): Likewise.
NTLMSSP in cli_establish_connection()
What we really need to do is kill off the pwd_cache code. It is horrible,
and assumes the challenge comes in the negprot reply.
packet which means I can extract the service and realm, so we should
now work with realms other than the local realm.
it also means we now check the list of OIDs given by the server just
in case it says that it doesn't support kerberos. In that case we
should fall back to NTLMSSP but that isn't written yet.
activate you need to:
- install krb5 libraries
- run configure
- build smbclient
- run kinit to get a TGT
- run smbclient with the -k option to choose kerberos auth
out the error handling into a bunch of separate functions rather than all
being handled in one big function.
Fetch error codes from the last received packet:
void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num);
uint32 cli_nt_error(struct cli_state *);
Convert errors to UNIX errno values:
int cli_errno_from_dos(uint8 eclass, uint32 num);
int cli_errno_from_nt(uint32 status);
int cli_errno(struct cli_state *cli);
Detect different kinds of errors:
BOOL cli_is_dos_error(struct cli_state *cli);
BOOL cli_is_nt_error(struct cli_state *cli);
BOOL cli_is_error(struct cli_state *cli);
This also means we now support CAP_STATUS32 as we can decode and understand
NT errors instead of just DOS errors. Yay!
Ported a whole bunch of files in libsmb to use this new API instead of the
just the DOS error.
This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
that libsmb/ creates a local tcp socket then launches smbd as a subprocess
attached to that socket. smbd thinks it is being launched from inetd.
to use it do the following:
- compile with -DSMB_REGRESSION_TEST
- run like this (also works with smbtorture etc)
export SMBD_TEST=1
export LIBSMB_PROG=bin/smbd
smbclient //server/share -Uuser%pass
obviously you need to setup a smb.conf etc. Using --prefix to configure
is useful.
The aim of all this stuff is to add a decent set of regression tests
to the build farm, so we know if smbd actually runs correctly on all the
platforms, not just builds. We can run smbtorture, masktest, locktest etc,
plus a bunch of smbclient scripts and any new tests we write.
This doesn't help much with nmbd (at least not yet) but its a good start.
send unaligned unicode strings sometimes!
Fixed our handling of the workgroup name tacked on the end of the
NT1 negprot response (a unaligned unicode)
fixed a couple of places where we should be using the message_end fns instead
of pre-calculated buffer lengths
back to working order. The main change is that the cli_*() RPC
functions from libsmb/*.c now should accept a struct cli_state*.
The reason for this is that rpcclient should establish the
connection to the server at startup so that it is not necessary
to keep the clear test or password hash in memory for each command.
enumports and enumprinters now works as well. lsa* functions
have been tested. SAMR calls may or may not work (one of the core
dumps I know), but it compiles :-)

I've currently got this code disabled by default as it is
incomplete. You enable it by setting a USE_UNICODE environment
variable. Once the support is complete this check will be removed and
the CAP_UNICODE capability bit will be the sole determination of
whether the client library code uses unicode
right now I have converted session_setup and tconx. I will do more fns
over the next few days.
see clistr.c for the new client side string interface. Luckily it
tends to make the code smaller and neater while adding unicode
support.
