coding have passed, but I could not find a way to get the OpenLDAP libraries
to reliably time out on any of the queries we make, *and* get correct error
returns. No, async calls and ldap_result does NOT work, or I was simply too
stupid to correctly interpret the OpenLDAP manpage and source.
We can not allow to hang indefinitely in an ldap query, especially not for
winbindd. "ldap timeout" now specifies the overall timeout for the complete
operation, that's why I increased that to 15 seconds.

"Jianliang Lu" <j.lu@tiesse.com>. Multi-string attribute changed to
linearised pstring due to ordering issues. A few other changes to
fix race conditions. I will add the tdb backend code next. This code
compiles but has not yet been tested with password history policy
set to greater than zero. Targeted for 3.0.6.

cache entry time comparisons in password lockout. Fixes problems where
pdb_ldap tries to delete the operational attribute modifyTimestamp when
deleting a user account.
bad time locally, updating the directory only for hitting the policy limit
or resetting.
This needed to be done at the passdb level rather than auth, because some
of the functions need to be supported from tools such as pdbedit. It was
done at the LDAP backend level instead of generically after discussion,
because of the complexity of inserting it at a higher level.
The login cache read/write/delete is outside of the ldap backend, so it could
easily be called by other backends. tdbsam won't call it for obvious
reasons, and authors of other backends need to decide if they want to
implement it.
boolean parameter that allows broken iconv conversions to work. Gets rid of the
nasty errno checks in mangle_hash2 and check_path_syntax and allows correct
return code checking.

I know this isn't pretty, but neither was our assumption that all strings
from the directory fit inside a pstring. There was no way this worked
before will all versions of usrmgr (for example, the only version of
mine that has the TS Confic button).
- Fill in the 'backup' idea of a domain, if the DC didn't supply one. This
doesn't seem to occour in reality, hence why we missed the typo.

- all the callers to pull_utf8_allocate() pass a char ** as the first
parammeter, so don't make them all cast it to a void **
nsswitch/winbind_util.c:
- Allow for a more 'correct' view of when usernames should be qualified
in winbindd. If we are a PDC, or have 'winbind trusted domains only',
then for the authentication returns stip the domain portion.
- Fix valgrind warning about use of free()ed name when looking up our
local domain. lp_workgroup() is maniplated inside a procedure that
uses it's former value. Instead, use the fact that our local domain is
always the first in the list.

This patch will change order how attributes are modified
from: add, delete
to: delete, add
This is needed to update single valued attributes in Novell NDS and
should not harm anyone else.
When smb.conf tells us to write to a read-only LDAP replica and we are
redirected by the LDAP server, the replication might take some seconds,
especially over slow links. This patch delays the next read after a rebind for
'ldap rebind sleep' milliseconds.
Metze, thanks for your patience.

* bug #280 (my fault) - initialize sambaNextUserRid and
sambaNextGroupRid
* Unix users shared vis LDAP or NIS between a samba domain member
of a Samba domain are not seen as domain users on the member servers.
not as local users.
to pstr_sprintf() and fstr_sprintf() to try to standardize.
lots of snprintf() calls were using len-1; some were using
len. At least this helps to be consistent.
Not strictly a bugfix, but it should considerably reduce the load we
put on LDAP servers given that at least nss_ldap on Linux keeps a
connection open.
And it should also stress our reconnect-code a bit more ;-)
Thanks to metze for this!

* move rid allocation into IDMAP. See comments in _api_samr_create_user()
* add winbind delete user/group functions
I'm checking this in to sync up with everyone. But I'm going to split
the add a separate winbindd_allocate_rid() function for systems
that have an 'add user script' but need idmap to give them a RID.
Life would be so much simplier without 'enable rid algorithm'.
The current RID allocation is horrible due to this one fact.
Tested idmap_tdb but not idmap_ldap yet. Will do that tomorrow.
Nothing has changed in the way a samba domain is represented, stored,
or search in the directory so things should be ok with previous installations.
going to bed now.
* remove idmap_XX_to_XX calls from smbd. Move back to the
the winbind_XXX and local_XXX calls used in 2.2
* all uid/gid allocation must involve winbindd now
* move flags field around in winbindd_request struct
* add WBFLAG_QUERY_ONLY option to winbindd_sid_to_[ug]id()
to prevent automatic allocation for unknown SIDs
* add 'winbind trusted domains only' parameter to force a domain member
server to use matching users names from /etc/passwd for its domain
(needed for domain member of a Samba domain)
* rename 'idmap only' to 'enable rid algorithm' for better clarity
(defaults to "yes")
code has been tested on
* domain member of native mode 2k domain
* ads domain member of native mode 2k domain
* domain member of NT4 domain
* domain member of Samba domain
* Samba PDC running winbindd with trusts
Logons tested using 2k clients and smbclient as domain users
and trusted users. Tested both 'winbind trusted domains only = [yes|no]'
This will be a long week of changes. The next item on the list is
winbindd_passdb.c & machine trust accounts not in /etc/passwd (done
via winbindd_passdb)
- Try better to add the appropriate mapping between UID and SIDs, based
on Get_Pwnam()
- Look for previous users (lookup by SID) and correctly modify the existing
entry in that case
- Map the root user to the Admin SID as a 'well known user'
- Save the LDAPMessage result on the SAM_ACCOUNT for use in the next 'update'
call on that user. This means that VL's very nice work on atomic LDAP
updates now really gets used properly!
- This also means that we know the right DN to update, without the extra
round-trips to the server.
Andrew Bartlett
We now always read the Domain SID out of LDAP. If the local secrets.tdb
is ever different to LDAP, it is overwritten out of LDAP. We also
store the 'algorithmic rid base' into LDAP, and assert if it changes.
(This ensures cross-host synchronisation, and allows for possible
integration with idmap). If we fail to read/add the domain entry, we just
fallback to the old behaviour.
We always use an existing DN when adding IDMAP entries to LDAP, unless
no suitable entry is available. This means that a user's posixAccount
will have a SID added to it, or a user's sambaSamAccount will have a UID
added. Where we cannot us an existing DN, we use
'sambaSid=S-x-y-z,....' as the DN.
The code now allows modifications to the ID mapping in many cases.
Likewise, we now check more carefully when adding new user entires to LDAP,
to not duplicate SIDs (for users, at this stage), and to add the sambaSamAccount
onto the idmap entry for that user, if it is already established (ensuring
we do not duplicate sambaSid entries in the directory).
The allocated UID code has been expanded to take into account the space
between '1000 - algorithmic rid base'. This much better fits into what
an NT4 does - allocating in the bottom part of the RID range.
On the code cleanup side of things, we now share as much code as
possible between idmap_ldap and pdb_ldap.
We also no longer use the race-prone 'enumerate all users' method for
finding the next RID to allocate. Instead, we just start at the bottom
of the range, and increment again if the user already exists. The first
time this is run, it may well take a long time, but next time will just
be able to use the next Rid.
Thanks to metze and AB for double-checking parts of this.
Andrew Bartlett
and pdb_ldap.
So far, it's just a function rename, so that the next patch can be a very
simple matter of copying functions, without worrying about what changed
in the process.
Also removes the 'static' pointers for the rebind procedures, replacing them
with a linked list of value/key lookups. (Only needed on older LDAP client
libs)
Andrew Bartlett
* remove 'winbind uid' and 'winbind gid' parameters (replaced
by current idmap parameter)
* create the sambaUnixIdPool entries automatically in the 'ldap
idmap suffix'
* add new 'ldap idmap suffix' and 'ldap group suffix' parametrer
* "idmap backend = ldap" now accepts 'ldap:ldap://server/' format
(parameters are passed to idmap init() function
Includes sambaUnixIdPool objectclass
Still needs cleaning up wrt to name space.
More changes to come, but at least we now have a
a working distributed winbindd solution.
