During building an object to send it on a GetNCChanges reply, it checks
the attributes and if any of them is a RODC filtered and the recipient
is a RODC, then such attribute is not sent.

This patch creates the samdb_is_rodc() function, which looks for
the NTDSDSA object for a DC that has a specific invocationId
and if msDS-isRODC is present on such object and it is TRUE, then
consider the DC as a RODC.
The new samdb_rodc() function uses the samdb_is_rodc() function
for the local server.

This choses an appropriate talloc context to attach the schema too,
long enough lived to ensure it does not go away before the operation
compleates.
Andrew Bartlett
The replPropertyMetaData may contain attrid values that we don't yet
have in the local schema. We need to deal with this - it is a serious
error, but we should not segfault.
Andrew Bartlett
The documentation shows that all these functions in fact use the same
flags variable type. To be consistent between functions, and to allow
easy reference to the WSPP docs, it is better for us to also use this
generic DrsOptions bitfield rather than one per operations.
This patch includes the framework for the implementation of all infoTypes of
the DsGetReplInfo() call, and includes the implementation for the first one,
the DS_REPL_INFO_NEIGHBORS.

When a client supplied an uptodateness_vector, we can use it to filter
what objects we return. This greatly reduces the amount of replication
traffic between DCs.
When windows abandons a DRS sync, it will sometimes re-use the same bind handle for
a new sync. This means we need to check the DN of the sync and blank the getnc_state
if the DN has changed.
This also fixes the UDV to use the highest uSN for the partition, not for
the whole SAM.
This patch adds a system_session cache, preventing us from having to
recreate it on every ldb open, and allowing us to detect when the same
session is being used in ldb_wrap
The DRSUAPI_DRS_ADD_REF flag tells the DRS server to run an UpdateRefs
call on behalf of the client after the DsGetNCChanges call. The lack
of support for this option may explain why the repsTo attribute was
not being created for w2k8-r2 replication partners.
The DsUpdateRefs calls takes a set of flags that indicates if the
server should ignore specific add/delete error codes.
This patch also exposes the core UpdateRefs call into a public
function, so that it can be called from DsGetNCChanges
For KERBEROS applications the realm should be upcase (function "lp_realm") but
for DNS ones it should be used lowcase (function "lp_dnsdomain"). This patch
implements the use of both in the right way.
When we indicate that a getncchanges request is not complete, we set
the more_data flag to true in the response. The client usually then
asks for the next block of data. If the client decides it wants to
skip that replication and do a different replication then we need to
make sure that the next call is in fact a continuation of the existing
call, and not a new call.
This relies on returning the results sorted by uSNChanged, as the
client uses the tmp_highest_usn in each result to see if progress is
being made.
- always fetch parentGUID from databases, don't rely on parentGUID in
attributes
- re-fetch nc root mesages to avoid the problem of dual messages for
roots
- support returning messages a chunk at a time, using max_object_count
from request
When this flag is specified in the request these attributes are treated as
secret: currentValue, dBCSPwd, initialAuthIncoming, initialAuthOutgoing,
lmPwdHistory, ntPwdHistory, priorValue, supplementalCredentials,
trustAuthIncoming, trustAuthOutgoing, unicodePwd
Their value is changed to NULL and the meta_data.originating_change_time to 0
In DsGetNCChanges we need to fill in the parentGUID and objectGUID of
each object, plus we need to filter out the rDN from the meta data,
and always send the instanceType
When the client tells us the highest_usn they have is N, then we want
to send them objects with usn>N, not>=N, as otherwise we end up
sending them the same object (the one with the highest uSN) again and
again.
uSNChanged>=N is good enough, and offers a possibility of a simple
optimisation where the partition module could look for that expression
and check the partitions sequence number, then avoid searching a
partition that doesn't have any records with a larger uSN.
We were relying on the uSNChanged>=n search always finding the DN of
the root of the partition, but this now doesn't happen very often as
we are now restricting when we change uSNChanged. This means we need
to always load the replUpToDateVector attribute from the NC root and
use it to populate the cursors in the return.
Our vampire code sends a zero GUID in the updaterefs calls. Windows
seems to ignore the GUID and use the DN in the naming context instead,
so I have changed our UpdateRefs server implementation to do the same.
With this change we can now vampire from s4<->s4 successfully! Now to
see if all the attributes came across correctly.
This patch implements DsReplicaSync by passing the call via irpc to
the repl server task. The repl server then triggers an immediate
replication of the specified partition.
This means we no longer need to set a small value for
dreplsrv:periodic_interval to force frequent DRS replication. We can
now wait for the DC to send us a ReplicaSync msg for any partition
that changes, and we immediately sync that partition.
Metze pointed out what the windows tool ldp.exe will examine repsTo
attributes on remote DCs, so we do in fact need to use the same format
that windows uses. This patch changes the server side implementation
of UpdateRefs to use the windows format
So far it returns the ctr6 responce without proper linked attributes
support and metadata. A couple of improvements are the filter in the search
uses '(uSNChanged>=N)', added extended dn search support, non-replicated attributes
are excluded from the result.
Templates just don't belong in the sam.ldb, as they don't obey any of
the other rules. This moves them to a seperate templates.ldb.
In samldb, this patch reworks the duplicate SID and Name detection
code, to use ldb_search_exp_fmt() rather than gendb_search. This
returns far more useful errors, which we now handle and report better.
The call to samdb_search_for_parent_domain() has been moved in samldb,
to allow both the account and SID uniqueness checks to be in the same
domain. This function also returns better errors.
dcesrv_drsuapi.c is updated for the new prototype of
samdb_search_for_parent_domain()

some issues in the NBT server (this was a false positive, but easily
worked around) and DRSUAPI server.
We should take care not to use the ldb_context as a talloc pool, and
to always ensure that any results from ldb_search() are moved off that
pool with talloc_steal or talloc_free().
To work around the issue in provision, for which I can find no fault
(other than a lot of work being done in provision), I've moved the
detector trigger to 400 additional blocks.

This patch changes a lot of the code in ldb_dn.c, and also
removes and add a number of manipulation functions around.
The aim is to avoid validating a dn if not necessary as the
validation code is necessarily slow. This is mainly to speed up
internal operations where input is not user generated and so we
can assume the DNs need no validation. The code is designed to
keep the data as a string if possible.
The code is not yet 100% perfect, but pass all the tests so far.
A memleak is certainly present, I'll work on that next.
Simo.

Add the kpasswd server to our KDC, implementing the 'original' and
Microsoft versions of the protocol.
This works with the Heimdal kpasswd client, but not with MIT, I think
due to ordering issues. It may not be worth the pain to have this
code go via GENSEC, as it is very, very tied to krb5.
This gets us one step closer to joins from Apple, Samba3 and other
similar implementations.

authenticated session down into LDB. This associates a session info
structure with the open LDB, allowing a future ldb_ntacl module to
allow/deny operations on that basis.
Along the way, I cleaned up a few things, and added new helper functions
to assist. In particular the LSA pipe uses simpler queries for some of
the setup.
In ldap_server, I have removed the 'ldasrv:hacked' module, which hasn't
been worked on (other than making it continue to compile) since January,
and I think the features of this module are being put into ldb anyway.
I have also changed the partitions in ldap_server to be initialised
after the connection, with the private pointer used to associate the ldb
with the incoming session.

This allowed the code from auth_domain to be shared - we now only

In order to link the resultant binary, samdb_search() has been moved
from deep inside rpc_server into lib/gendb.c, along with the existing

The thing that finally convinced me that minimal includes was worth
pursuing for rpc was a compiler (tcc) that failed to build Samba due
to reaching internal limits of the size of include files. Also the
fact that includes.h.gch was 16MB, which really seems excessive. This
patch brings it back to 12M, which is still too large, but
better. Note that this patch speeds up compile times for both the pch
and non-pch case.
This change also includes the addition iof a "depends()" option in our
IDL files, allowing you to specify that one IDL file depends on
another. This capability was needed for the auto-includes generation.
