- 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
|
|
|
|
Use msg->elements for the new element values
|
|
Even though we don't create deleted objects ourselves yet, we need to
pass along deleted objects we receive from other replication partners
|
|
getncchanges
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
|
|
When this flag is specified in the request we should return
for ncRoot only and so scope of search is LDB_SCOPE_BASE.
|
|
When this flag is specified in the request we shouldn't use the
uptodateness vector in the request.
|
|
|
|
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
|
|
|
|
This might help the windows client with ordered requests. Later we
need to support the "ancestors" mode flag.
|
|
These additional debug messages were added to help us track down
w2k8->s4 domain join
|
|
|
|
|
|
|
|
There is also an option to disable the security check
by specifying in the smb.conf file:
drs:disable_sec_check = true
|
|
|
|
|
|
|
|
This uses async RPC forwarding for the DsReplicaSync call
|
|
The key DRS calls should only be allowed by administrators or domain
controllers
|
|
The getncchanges uSN is in our local space, so we must compare it to
the local_usn in replPropertyMetaData
|
|
a rename may have no attribute changes
|
|
At least on the command line the braces are needed. Strange.
|
|
It's useful seeing the object count without as much detail
|
|
Without this the client will not update its repsFrom highest_usn values
|
|
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.
|
|
We now have dsdb_loadreps() and dsdb_savereps()
|
|
|
|
|
|
|
|
An early return here didn't do any good :-)
|
|
When a DsAddEntry is used to create a nTDSDSA object we need to also
create the SPNs for the NTDS GUID in the servers machine account.
|
|
Right now parentGUID is a normal attribute in s4, but it should be
generated, which means we need to ask for it in a search if we want to
use it.
|
|
This means we now get passwords vampired correctly for s4<->s4
replication.
|
|
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.

thanks to metze for pointing this out
|
|
These two arrays need to be in sync, as they are walked in sync by the
client
|
|
It is easier to understand without the heavy nesting
|
|
DsAddEntry now seems to work for simple tests
|
|
These will get quite complex eventually, I think we are better
separating them so the code is a bit easier to follow
|
|
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
