dsdb_schema_pfm_contains_drsuapi_pfm()
dsdb_schema_pfm_contains_drsuapi_pfm() is part of reimplemented
prefixMap interface.
This name was choosen to clearly show, that this a week verification
in case we want to determine if remote schema is changed.

dsdb_get_oid_mappings_drsuapi() just need to call
dsdb_drsuapi_pfm_from_schema_pfm() to get filled-in DRSUAPI
prefixMap.
Perhaps it won't be bad to rename this function to have
more expressive name in the future

Also, dsdb_load_oid_mappings_drsuapi() was reimplemented to use
dsdb_schema_pfm_from_drsuapi_pfm() function to load
drsuapi_prefixMap into schema->prefixmap

The biggest change is that 'oid' field is transmited in binary format.
Also the field name is changed to 'binary_oid' so that
field format to be clear for callers.
After those changes, Samba4 should work the way it works before -
i.e. no added value here but we should not fail when
partial-oid is part of prefixMap transmited from Win server.
Also, thre is a bug in this patch - partial-binary-OIDs are
not handled correctly. Partial-binary-OIDs received during
replication will be encoded, but not handled correctly.

This avoids using an ldb_search(), which would run from the top of the
module stack. This will help us load the schema before the partitions
are initialised.

These additional debug messages were added to help us track down

This is currently only triggered via Samba4's schema code.

Using DLIST_ADD_END() to construct a long list is very inefficient (it
is O(n^2). These lists are not ordered, so using DLIST_ADD() is much
better.

This changes dsdb_write_prefixes_from_schema_to_ldb() to use an
internal talloc hirarchy, so we can safely give it a NULL context from
the python.
It also fixes manual construction of the ldb_message - we now use the
right helper functions.

The aim is to create a function that is more easily wrapped for
python, so that we can write the updated prefixMap in an upgrade
script.

The problem is that samdb_result_string() and
ldb_msg_find_attr_as_string() both simply cast the string, rather than
ensuring the return value is NULL terminated. This may be best
regarded as a flaw in LDB, but fixing it there is going to be more
difficult.

This triggered a failure in the updateNow schema test, as the current
global schema was not being updated when a new schema element was
added

Using ldb unique indexes for samAccountName doesn't work with DRS as
the other DC may send us a deleted record (tombstone record), which
has the same samAccountName as an existing record. That would then
create two records in the same partition with the same samAccountName.
So we needed to put back the logic in samldb.c which explicitly
checked whether a samAccountName already exists on add
|
|
The previous code incorrectly assumed that attributes such as
subClassOf come over the wire as strings. In fact they come over as 32
bit integers which refer to goversIDs. We have to post-process these
as it sometimes happens that a governsID comes over the wire before
the record that defines what it means.

This is all working towards supporting the full WSPP schema without a
major performance penalty.
We now use binary searches when looking up classes and attributes. We
also avoid the loop loading the attributes into ldb, by adding a hook
to override the ldb attribute search function in a module. The
attributes can thus be loaded once, and then saved as part of the
global schema.
Also added support for a few more key attribute syntaxes, as needed
for the full schema.

|
|
The short-to-long name canonicalisation rules use the schema, so
clearly they won't work when loading it.

This search uses the index, and is not recursive, so should avoid the
major performance problem with the current sorted schema load.
The ad2oLschema code (recently moved to provision-backend) no longer
needs the schema to be sorted.

This includes things such as allowed attributes, which were not
populated into the schema structure before.

The previous ldb_search() interface made it way too easy to leak results,
and being able to use a printf-like expression turns to be really useful.
|
|
This should make schema manipulation a little easier to follow.

This reads the schema from the in-memory structure, when the magic
attributes are requested. The code is a modified version of that used
in the ad2oLschema tool (now shared).
The schema_fsmo module handles the insertion of the generated result.
As such, this commit also removes these entries from the setup/schema.ldif
Metze's previous stub of this functionality is also removed.

LDB does not know about nor process the AD schema, so it makes no
sense to have this tool there. I've been changing it anyway, to use a
common schema manipulation library, and will enhance these links in
the future.

This implements the logic in the schema_fsmo_add() function,
but it only calls a dummy dsdb_create_prefix_mapping() yet.

To make Samba4, using the python provision system, pass this test
required some major rework. Untested code is broken code, and some of
the refactoring for a seperate provision test (which also now passes)
broke things.
Similarly, the iconv work has compiled, but these codepaths have never
been run (NULL pointer de-reference).
In working to use a local, rather than global, loadparm context, and
to support using a target directory, a few things needed to be
reworked, particularly around path handling.
