Currenly implemented functions are:
dsdb_schema_pfm_new(), dsdb_schema_pfm_make_attid()
and dsdb_schema_pfm_oid_from_attid()
|
|
Currenly those tests cover only the main part of the interface,
i.e. dsdb_schema_pfm_new(), dsdb_schema_pfm_make_attid()
and dsdb_schema_pfm_oid_from_attid()

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.

This allows us to figure out what the system can add, which will not
be in possibleInferiors due to the systemOnly flag.

AD has the concept of a DN prefixed with B:NN:XXXXXX: that contains a
binary blob. We need to support those in order to give correctly
formatted binary blobs for things like wellKnownObjects
This implementation is not ideal, as it allows for binary blobs on all
DNs, whereas it should only allow them on those with a syntax of
2.5.5.7. We should clean this up in the future, but meanwhile this
implementation at least gets us a working DC join of w2k8 to s4.
This patch also uses a static function for marking DNs as invalid,
which is very useful when debugging this code, as you can break on it
in gdb.

These additional debug messages were added to help us track down
w2k8->s4 domain join
|
|
This is currently only triggered via Samba4's schema code.

Currently disabled. The search will be greatly modified,
also the object tree stuff will be simplified.

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.
|
|
In time, this should avoid the astounding (order) complexity of the
objectclass sorting in objectclass.c eventually.

We were trying to encode strings like 'top' as integers, without first
looking them up in our schema. We need special handling for all the
attributes that contain attributeID_id or governsID_id fields that
should be translated first before encoding.
|
|
|
|
Here we just need to map the oid string in the ldb value to
the ATTRTYP id.

This replace the dsdb_syntax_FOOBAR_ldb_to_drsuapi function,
which was left as a TODO code. Implementation in both added functions
is completely identical and probably should differ in the future.
|

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.
Andrew Bartlett
|
|
|
|
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
|
|
This helps ensure we don't load the schema too often in the provision
(allowing a reference in of the schema before the modules load).
Andrew Bartlett
|
|
This allows us to load the schema against one ldb context, but apply
it to another. This will be useful in the provision script, as we
need the schema before we start the LDAP server backend.

Before this change, the first opener of the sam ldb context would
become the owner of the global schema, then the autofree context got a
reference to the schema. Any subsequent opens of the sam ldb also got
a reference. This meant that the talloc hierarchy was inconsistent
between the first sam ldb open and subsequent opens. With this change
the autofree context becomes the owner of the global schema, and all
ldb contexts get a reference.
|
|
This removes a number of cases where we did a cast into a const char *
of an ldb_val. While convention is to alway have an extra \0 at
data[length] in the ldb_val, this is not required, and does not occour
at least on build farm host 'svart'.

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.
|
|
|
|
I tried hard to not change the program logic. Should fix bug #6439.
|
|
- LDB handles now all 32-bit integer attributes correctly (also with overflows)
according to the schema
- LDAP backends handle the attributes "groupType", "userAccountControl" and
"sAMAccountType" correctly. This handling doesn't yet use the schema but
the conversion file "simple_ldap.map.c" which contains them hardcoded.
Did also a refactoring of the conversion function there.
- Bug #6136 should be gone

We are probably still using more memory here than we need to. That
needs to be looked at.
|
|
Sadly it still segfaults at this stage
