As abartlet rememberd me NT_STATUS_IS_ERR != !NT_STATUS_IS_OK
This patch will cure the problem.
Working on this one I found 16 functions where I think NT_STATUS_IS_ERR() is
used correctly, but I'm not 100% sure, coders should check the use of
NT_STATUS_IS_ERR() in samba is ok now.
Simo.

The code was nice, but put in the wrong place (group mapping) and not
supported by most of the code, thus useless.
We will put back most of the code when our infrastructure will be changed
so that privileges actually really make sense to be set.
This is a first patch of a set to enhance all our mapping code cleaness and
stability towards a sane next beta for 3.0 code base
Simo.

We really need idmap_ldap to have a good solution with ldapsam, porting
it from the prvious code is beeing made, the code is really simple to do
so I am confident it is not a problem to commit this code in.
Not committing it would have been worst.
I really would have been able to finish also the group code, maybe we can
put it into a followin release after 3.0.0 even if it may be an upgrade
problem.
The code has been tested and seem to work right, more testing is needed for
corner cases.
Currently winbind pdc (working only for users and not for groups) is
disabled as I was not able to make a complete group code replacement that
works somewhat in a week (I have a complete patch, but there are bugs)
Simo.

to the system. This means that we always run Get_Pwnam(), and can never add
FOO when foo exists on the system (the idea is to instead add foo into
the passdb, using it's full name, RID etc).

I really don't like passing flags down to inner routines and
complicated if/else conditions, but this time he might be right. ;-)

* pdbedit -i -e sets all SAM_ACCOUNT elements
to CHANGED to satisfy the new pdb_ldap.c handling
* pdbedit -g transfers group mappings. I made this
separate from the user database, as current installations
have to live with a split backend.
So, if you are running 3_0 alphas with LDAP as a backend
and upgrade to the next 3_0 alpha, you should call
pdbedit -i tdbsam -e ldapsam -g
to transfer your group mapping database to LDAP.
You certainly have to have all your groups as posixGroup
objects in LDAP and adapt the LDAP schema before this
call.

This patch catches up on the rest of the work - as much string checking
as is possible is done at compile time, and the rest at runtime.
Lots of code converted to pstrcpy() etc, and other code reworked to correctly
call sizeof().

The work here includes:
- metze' set/changed patch, which avoids making changes to ldap on unmodified
attributes.
- volker's group mapping in passdb patch
- volker's samsync stuff
- volkers SAMR changes.
- mezte's connection caching patch
- my recent changes (fix magic root check, ldap ssl)

fixed tdbsam memory corruption (and segfault)
reducing calls to pdb_uid_to_user_rid and countrary to 0 to move to a non alghoritmic rid allocation with some passdb modules.
(This used to be commit 9836af7cd6)
much saner :-).
Change to pdb_init_sam()/pdb_free_sam() loop rather than reset based due to
the talloc basis.

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.
(This used to be commit ff354c99c5)
These strings are allocated using talloc(), either using its own memory context
stored on the SAM_ACCOUNT or one supplied by the caller.
The pdb_init_sam() and pdb_free_sam() function have been modifed so that a call
to pdb_free_sam() will either clean up (remove hashes from memory) and destroy
the TALLOC_CTX or just clean up depending on who supplied it.
The pdb_init_sam and pdb_free_sam functions now also return an NTSTATUS, and I
have modified the 3 places that actually checked these returns.
The only nasty thing about this patch is the small measure needed to maintin
interface compatability - strings set to NULL are actually set to "".
This is becouse there are too many places in Samba that do strlen() on these
strings without checking if they are NULL pointers.
A supp patch will follow to set all strings to "" in pdb_default_sam().

Thou shalt not reference SAM_ACCOUNT members directly - always use
pdb_get/pdb_set.
This is achived by making the whole of SAM_ACCOUNT have a .private member,
where the real members live. This caught a pile of examples, and these have
beeen fixed.
The pdb_get..() functions are 'const' (have been for some time) and this
required a few small changes to constify other functions.
I've also added some debugs to the pdb get and set, they can be removed if
requested.
I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb
interface, but I need the flags info to do it properly.
The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such
I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result.
Finally, any and all testing is always appriciated - but the basics seem to
work.

members (such as uid and gid). This way we will be able to
keep ourselves from writing out default smb.conf settings when
the admin doesn't want to, That part is not done yet.
Tested compiles with ldap/tdb/smbpasswd. Tested connection with smbpasswd
backend.
oh...and smbpasswd doesn'y automatically expire accounts after 21 days
from the last password change either now. Just ifdef'd out that code
in build_sam_account().
Will merge updates into 2.2 as they are necessary.
