- Fix segfaults in the 'net ads' commands when no password is provided
- Readd --with-ldapsam for 2.2 compatability. This conditionally compiles the
old options, but the actual code is available on all ldap systems.
- Fix shadow passwords (as per work with vl)
- Fix sending plaintext passwords to unicode servers (again vl)
- Add a bit of const to secrets.c functions
- Fix some spelling and grammer by vance.
- Document the -r option in smbgroupedit.
There are more changes in HEAD, I'm only merging the changes I've been involved
with.

This commit builds on the auth subsystem to give Samba support for trusting NT4
domains. It is off by default, but is enabled by adding 'trustdomain' to the
'auth methods' smb.conf paramater.
Tested against NT4 only - there are still some issues with the join code for
Win2k servers (spnego stuff).
The main work TODO involves enumerating the trusted domains (including the RPC
calls to match), and getting winbind to run on the PDC correctly.
Similarly, work remains on getting NT4 to trust Samba domains.

Remove a stray 'unbecome_root()' in the ntdomain an auth failure case.
Only allow trust accounts to request a challange in srv_netlogon_nt.c.
Currently any user can be the 'machine' for the domain logon. MERGE for 2.2.

this is needed because W2K will send a TCP reset to any open
connections that have not done a negprot when a second connection is
made. This meant that under heavy netlogon load a Samba domain member
would fail authentications.

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)

info3. These are RIDs, and it only makes sense to combine them with the domain
SID returned with them. This is important for trusted domains, where that sid
might be other than the one we currently reterive from the secrets.tdb.
Also remove the become_root()/unbecome_root() wrapper from around both
remaining TDB users: Both are now initialised at smbd startup.

Samba now features a pluggable passdb interface, along the same lines as the
one in use in the auth subsystem. In this case, only one backend may be active
at a time by the 'normal' interface, and only one backend per passdb_context is
permitted outside that.
This pluggable interface is designed to allow any number of passdb backends to
be compiled in, with the selection at runtime. The 'passdb backend' paramater
has been created (and documented!) to support this.
As such, configure has been modfied to allow (for example) --with-ldap and the
old smbpasswd to be selected at the same time.
This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua.
These two backends accept 'non unix accounts', where the user does *not* exist
in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to
avoid conflicts in the algroitmic mapping of RIDs, they use the values
specified in the 'non unix account range' paramter - in the same way as the
winbind ranges are specifed.
While I was at it, I cleaned up some of the code in pdb_tdb (code copied
directly from smbpasswd and not really considered properly). Most of this was
to do with % macro expansion on stored data. It isn't easy to get the macros
into the tdb, and the first password change will 'expand' them. tdbsam needs
to use a similar system to pdb_ldap in this regard.
This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I
don't have the test facilities for these. I plan to incoroprate at least
pdb_ldap into this scheme after consultation with Jerry.
Each (converted) passdb module now no longer has any 'static' variables, and
only exports 1 init function outside its .c file.
The non-unix-account support in this patch has been proven! It is now possible
to join a win2k machine to a Samba PDC without an account in /etc/passwd!
Other changes:
Minor interface adjustments:
pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*.
pdb_update_sam_account() no longer takes the 'override' argument that was being
ignored so often (every other passdb backend). Extra checks have been added in
some places.
Minor code changes:
smbpasswd no longer attempts to initialise the passdb at startup, this is
now done on first use.
pdbedit has lost some of its 'machine account' logic, as this behaviour is now
controlled by the passdb subsystem directly.
The samr subsystem no longer calls 'local password change', but does the pdb
interactions directly. This allow the ACB_ flags specifed to be transferred
direct to the backend, without interference.
Doco:
I've updated the doco to reflect some of the changes, and removed some paramters
no longer applicable to HEAD.

Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps
them around for a long time - often past the next call...
This adds a getpwnam_alloc and a getpwuid_alloc to the collection.
These function as expected, returning a malloced structure that can be
free()ed with passwd_free(&passwd).
This patch also cuts down on the number of calls to getpwnam - mostly by
taking advantage of the fact that the passdb interface is already
case-insensiteve.
With this patch most of the recursive cases have been removed (that I know
of) and the problems are reduced further by not using the sys_ interface
in the new code. This means that pointers to the cache won't be affected.
(This is a tempoary HACK, I intend to kill the password cache entirly).
The only change I'm a little worried about is the change to
rpc_server/srv_samr_nt.c for private groups. In this case we are getting
groups from the new group mapping DB. Do we still need to check for private
groups? I've toned down the check to a case sensitve match with the new code,
but we might be able to kill it entirly.
I've also added a make_modifyable_passwd() function, that copies a passwd
struct into the form that the old sys_getpw* code provided. As far as I can
tell this is only actually used in the pass_check.c crazies, where I moved
the final 'special case' for shadow passwords (out of _Get_Pwnam()).
The matching case for getpwent() is dealt with already, in lib/util_getent.c
Also included in here is a small change to register the [homes] share at vuid
creation rather than just in one varient of the session setup. (This picks
up the SPNEGO cases). The home directory is now stored on the vuid, and I
am hoping this might provide a saner way to do %H substitions.
TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change
the remaining sys_getpwnam() callers to use getpwnam_alloc() and move
Get_Pwnam to return an allocated struct.

Also set the default value of all the allocated strings to "" to avoid changing
the interface (becouse pdb_get...() would point to a null string, rather than a
null pointer and parts of samba rely on that).

This occured when the attempt to contact the PDC failed. The connection code
has already shut down the connection, and 'free'ed the cli or has never
initialised it in the first place.

(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

Replace this with some flags that *we* define. We can do a mapping later
if we actually get some more reliable info about what passwords are actually
valid.

Also more insertion of parenthesis to handle struct members called
'free'.
You can now get useful dmalloc output, as long as it is compatible
with your C library. On RH7.1 it looks like you have to rebuild
dmalloc to allow free(0) by default, because something in libcrypt
does that. (sigh)

The auth_authsupplied_info typedef is now just a plain struct - auth_context,
but it has been modified to contain the function pointers to the rest
of the auth subsystem's components.
(Who needs non-static functions anyway?)
In working all this mess out, I fixed a number of memory leaks and moved the
entire auth subsystem over to talloc().
Note that the TALLOC_CTX attached to the auth_context can be rather long-lived,
it is provided for things that are intended to live as long. (The
global_negprot_auth_context lasts the whole life of the smbd).
I've also adjusted a few things in auth_domain.c, mainly passing the domain as
a paramater to a few functions instead of looking up lp_workgroup(). I'm
hopign to make this entire thing a bit more trusted domains (as PDC) freindly
in the near future.
Other than that, I moved a bit of the code around, hence the rather messy diff.

- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c
- It hasn't been used by anything else since smbpasswd lost its -j
- Add a TALLOC_CTX to the auth subsytem. These are only valid for the length
of the calls to the individual modules, if you want a longer context hide it
in your private data.
Similarly, all returns (like the server_info) should still be malloced.
- Move the 'ntdomain' module (security=domain in oldspeak) over to use the new
libsmb domain logon code. Also rework much of the code to use some better
helper functions for the connection - getting us much better error returns
(the new code is NTSTATUS).
The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for
the LUID feilds is sufficient, or if we should do random LUIDs as per the old
code.
Similarly, I'll move winbind over to this when I get a chance.
This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in
rpc_client, at least as far as smbd is concerned.
While I've given this a basic rundown, any testing is as always appriciated.
