Change our Domain controller lookup routines to more carefully seperate
DNS names (realms) from NetBIOS domain names.
Until now, we would experience delays as we broadcast lookups for DNS names
onto the local network segments.
Now if DNS comes back negative, we fall straight back to looking up the
short name.

Changes to our PAM code to cope with the fact that we can't handle some
domains (in particular, the domain of the current machine, if it is not a PDC)
By changing the error codes, we now return values that PAM can correctly
use for better stacking of PAM modules - in particular of the password change
module.
This allows pam_winbind to co-exist with other pam modules for password changes.

Try to gain a bit more consistancy in the output of usernames from ntlm_auth:
Instead of returning a name in DOMAIN\user format, we now return it in the
same way that nsswtich does - following the rules of 'winbind use default
domain', in the correct case and with the correct seperator.
This should help sites who are using Squid or the new SASL code I'm working
on, to match back to their unix usernames.
--
Get the DOMAIN\username around the right way (I had username\domain...)
Push the unix username into utf8 for it's trip across the socket.

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...

workstation, we have to use the workstation type, if we have a BDC account,
we must use the BDC type - even if we are pretending to be a workstation
at the moment.
Also actually store and retreive the last change time, so we can do
periodic password changes again (for RPC at least).
And finally, a couple of minor fixes to 'net'.

- Add a 'privileged' mode to Winbindd. This is achieved by means of a directory
under lockdir, that the admin can change the group access for.
- This mode is now required to access with 'CRAP' authentication feature.
- This *will* break the current SQUID helper, so I've fixed up our ntlm_auth
replacement:
- Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a
challenge.
- Use this to make our ntlm_auth utility suitable for use in current Squid 2.5
servers.
- Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates
are needed.
- Now uses fgets(), not x_fgets() to cope with Squid environment (I think
somthing to do with non-blocking stdin).
- Add much more robust connection code to wb_common.c - it will not connect to
a server of a different protocol version, and it will automatically try and
reconnect to the 'privileged' pipe if possible.
- This could help with 'privileged' idmap operations etc in future.
- Add a generic HEX encode routine to util_str.c,
- fix a small line of dodgy C in StrnCpy_fn()
- Correctly pull our 'session key' out of the info3 from th the DC. This is
used in both the auth code, and in for export over the winbind pipe to
ntlm_auth.
- Given the user's challenge/response and access to the privileged pipe,
allow external access to the 'session key'. To be used for MSCHAPv2
integration.

This updates the 'winbind' authentication module and winbind's 'PAM' (actually
netlogon) code to allow smbd to cache connections to the DC.
This is particulary relevent when we need mutex locks already - there is no
parallelism to be gained anyway.
The winbind code authenticates the user, and if successful, passes back the
'info3' struct describing the user. smbd then interprets that in exactly the
same way as an 'ntdomain' logon.
Also, add parinoia to winbind about null termination.

This patch fixes the segfaults I introduced in the previous conneciton caching
patch. It cleans up the connection cache a *lot* - in particular it adds
significant robustness to the operation.
If a the DC goes down, we no longer fail the next operation - the code checks
if the connection died during one of its own operations on the socket, and
restarts the conneciton as required.
There is still a memory leak in here somewhere - but this code also cleans up a
number of these.
Also added is the abilty to sepecify the domain of the 'get around restrict anonymous'
user that winbind uses.

Add a connection cache to the netlogon pipe. This makes a *massive* difference
to the time-per-auth. Also fix up *some* of the memory leaks in other
connection caches.
Add some debugging messages for the is_connected() code. I'm thinking we
should get a client implementation of SMBecho and call it here - as it would
allow us to always know the DC is around before we start.
Down the debug level for some of the pam_winbind code - I'll probably down it
further when I'm finished debugging.

This adds code to do generic PAM -> NTSTATUS and NTSTATUS -> PAM error
conversions, and uses them to make the error handling in pam_winbind sane.
In particular, pam_winbind now uses PAM error codes, not silly '-1, -2 ...'
stuff, and logs the NTSTATUS error that winbind now sends over the pipe.
Added code to wbinfo to display these - makes a big difference in debugging
winbindd.
The main change here is the code to allow pam_winbind password changing to
correctly stack - This code ripped from pam_unix, and the copyright attached.
(Same as for all pam modules, including pam_winbind)

<a.bokovoy@sam-solutions.net>.
The idea is the domain\username is rather harsh for unix systems - people don't
expect to have to FTP, SSH and (in particular) e-mail with a username like
that.
This 'corrects' that - but is not without its own problems.
As you can see from the changes to files like username.c and wb_client.c (smbd's
winbind client code) a lot of assumptions are made in a lot of places about
lp_winbind_seperator determining a users's status as a domain or local user.
The main change I will shortly be making is to investigate and kill off
winbind_initgroups() - as far as I know it was a workaround for an old bug in
winbind itself (and a bug in RH 5.2) and should no longer be relevent.
I am also going to move to using the 'winbind uid' and 'winbind gid' paramaters
to determine a user/groups's 'local' status, rather than the presence of the
seperator.
As such, this functionality is recommended for servers providing unix services,
but is currently less than optimal for windows clients.
(TODO: remove all references to lp_winbind_seperator() and
lp_winbind_use_default_domain() from smbd)

The winbind connection caching code isn't exactly a plesent beast, and there is

(various e-mails announcements merged into some form of commit message below:)
This patch which adds basics of universal groups support
into Samba 3. Currently, only Winbind with RPC calls supports this, ADS
support requires additional (possibly huge) work on KRB5 PAC. However,
basic infrastructure is here.
This patch adds:
1. Storing of universal groups for particular user logged into Samba
software (smbd/ two winbind-pam methods) into netlogon_unigrp.tdb as array
of uint32 supplemental group rids keyed as DOMAIN_SID/USER_RID in tdb.
2. Fetching of unversal groups for given user rid and domain sid from
netlogon_unigrp.tdb.
Since this is used in both smbd and winbindd, main code is in
source/lib/netlogon_uingrp.c. Dependencies are added to AUTH_OBJ as
UNIGRP_OBJ and WINBINDD_OBJ as UNIGRP_OBJ.
This patch has had a few versions, the final version in particular:
Many thanks to Andrew Bartlett for critics and comments, and partly
rewritten code.
New:
- updated fetching code to changed byte order macros
- moved functions to proper namespace
- optimized memory usage by reusing caller's memory context
- enhanced code to more follow Samba coding rules
Todo:
- proper universal group expiration after timeout

It adds a 'ping' request, just to check winbind is in fact alive
It also changes winbindd_pam_auth_crap to take usernames and domain seperatly.
(backward incompatible change, needs merge to 2.2, but this is not yet released
code, so no workarounds)
Finally, it adds some debugs and fixes a few memory leaks (uses talloc to do
it).

Also removed the dependency on auth_util.o, which makes things nicer.
Finally, this kills off the NECESSARY_BECAUSE_SAMBA_DEPENDENCIES_ARE_SO_BROKEN_OBJ

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.
