This broke DRS replication from samba to windows
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

We should not be going to the top of the module stack
|
|
It is valid to get a NULL GUID over DRS for a deleted forward link. We
need to match by DN if possible when seeing if we should update an
existing link.

This ensures that a link is not seen before the object it points to
|
|
We were sending zero GUIDs. Not good!

I think we probably have more work to do on the sort order, but this
brings us a bit closer.
|
|
the sorting is quite delicate, and easier to get right in the
getncchanges code

sometimes windows sends us a zero GUID in a DRS DN.

windows sends objectclasses in DRS in the opposite order to what LDAP
uses
|
|
This allows you to call dsdb_module_*() functions while including the
current module in the module stack to be used

This is needed to support DSDB_FLAG_OWN_MODULE

Use ^1 everywhere, to ensure it works for both forward and backward
links
|
|
We should overwrite an existing entry if found

Added two debugging parametric options
drs:max object sync =
drs:extra filter =

This uses the RELAX control and checking of single valued attributes
in ldb modules to avoid problems with multi-valued links where all
values but one are deleted
|
|
This is used in conjunction with the RELAX control, to check for
violations of single value rules for linked attributes
|
|
We need to send non-upgraded links using the old format
|
|
This is used to detect if a link has been stored in the w2k3 extended
format
|
|
When using w2k3 linked attributes we are allowed to have multiple
values on a single valued attribute. This happens when the other
values are deleted.
Setting the RELAX control tell the ldb-tdb backend to not check for
this on replace, which means the caller has to check for single valued
violations.
|
|
When any value of a w2k formatted linked attribute is modified,
upgrade the links.
|
|
|
|
We need this for the linked attribute meta data

We need a separate RMD_LOCAL_USN to allow us to tell what attributes
need to be sent in a getncchanges request. Thanks to Metze for
pointing this out.

The linked_attributes module only has to deal with renames now, as
other linked attribute updates happen in repl_meta_data. This allows
it to be much simpler.
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

|
This makes updating the links a bit easier
|
|
backlinks in add and delete operations can be processed immediately,
rather than at the end of a transaction. This can save on backlink
list processing time.
|
|
This is now handled in the repl_meta_data module
|
|
This also handles the backlink creation that was previously in the
linked_attributes module

This implements repmld_delete(), which handles the meta_data updates
for an object when deleting. A delete gets mapped to a combination
of a rename followed by a modify request, which has the effect of
moving the object into the Deleted Objects container.
This is based on the code from Eduardo Lima
<eduardoll@gmail.com>. Eduardo's code was modified to take account of
the linked attributes changes that Andrew and I have been working on.

delete handling is now moved into repl_meta_data
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
|

We don't want to be debugging two different code paths through the ldb
module stack, so better to always do the work of repl_meta_data, even
for a standalone server
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

|
We need to use ldb_rename() and not dsdb_module_rename() here as we
need the rename to be processed by the current module
|
|
This functionality has moved into repl_meta_data
|
|
backlinks need more careful handling now that we store the additional
meta data for deleted links. It is easier to handle this in
repl_meta_data than in linked_attributes.
Eventually linked_attributes will disappear, with the functionality
moved into repl_meta_data.

We now have the core code for handling storage of linked attribute
meta-data with local modifies

When in functional levels above w2k, we need to store much richer meta
data about linkked attributes. We also need to keep deleted linked
attributes around to allow the deletion to be propogated to other DCs.
