Just 'refresh_fn' and 'loaded_from_module' are copied.
I left 'reload_seq_number' set to 0 intentionally, so that
this Schema cache will looks like a very old one to ,refresh_fn'.
This way, if this shallow copy is attached to LDB, it will be
refreshed as soon as possible by 'refresh_fn'.
We may have no prefix for the remote ATTID (remote OID strictly speaking)
So this is the place for us to update our local prefixMap
adding a prefix for the numeric OID we've recived
in dsdb_attribute_drsuapi_to_ldb() function.
drsuapi_DsReplicaAttribute *in parameter come from remote DC
so we can't rely on in->attid to map it directly to an
dsdb_attribute in our local schema cache
Without this change, when a schema is set to ldb, the
effect is that dsdb_get_schema() returns global_schema
preferably.
Thus we end up with two schemas in effect:
- global one, which is the old one and it is still used everywhere
- new one, which is just cached in ldb, but can't be used, as
there is no way to access it
This is consistent with the test names used by selftest, should
make the names less confusing and easier to integrate with other tools.

dsdb_schema_pfm_attid_from_oid() instead of
dsdb_schema_pfm_make_attid() as those functions are
supposed to return ATTIDs only for OIDs we already know about
(i.e. are in prefixMap)

read-write functions.
dsdb_schema_make_attid() may change prefixMap implicitly
and this is not always desired behavior.
The problem was that
(1) callers had no control on this behavior
(2) callers had no way to know wheter prefixMap has been
changed which can lead to hard to find bugs like
prefixMap is changed in read operation
Currently it is mapped to Octet String LDAP syntax
for comparison purposes.
According to LDAP rfc we should be using same comparison
as Directory String (LDB_SYNTAX_DIRECTORY_STRING), but case sensitive.
But according to ms docs binary compare should do the job:

This implementation doesn't use prefixMap/Schema to validate
numericoid OIDs. We may not have this OID yet, so I see no point
checking schema for if we have it.
Side effect of using prefixMap/Schema for validating numericoids
is that we mistakenly add the OID to the prefixMap.
This led to a corrupted prefixMap in LDB.

these functions operate on ldb_modules, so they should be in the
ldb_modules directory. They also should return ldb errors codes, not
WERROR codes, as otherwise the error can be hidden from the ldap
caller
This re-arrangement fixes a dependency loop in the schema/samdb code.

We have ldb_msg_find_attr_as_* calls which do exactly the same. Therefore this
reduces only code redundancies.

This structure is intended to hold context-dependent data.
Syntax-conversion and object-conversion functions need
that data to convert objects and attributes from drs-to-ldb
and ldb-to-drs correctly.
For instance: ATTID value depends on whether we are converting
object from partition different that Schema partition.
Few comments split on several lines also...

this replaces "return LDB_ERR_OPERATIONS_ERROR" with "return ldb_operr(ldb)"
in places in the dsdb code where we don't already explicitly set an
error string. This should make is much easier to track down dsdb
module bugs that result in an operations error.
It was reported by aatanasov that we kept around one whole schema per
modification made. This does not fix that, but I hope moves us closer
to a fix
The most important part of the fix is that:
- if (schema_out != schema_in) {
- talloc_unlink(schema_in, ldb);
- }
was the wrong way around. This is now handled in the schema_set calls.

Especially the "free"s after "ldb_msg_diff" are very important since the diff
message is allocated on the long-living LDB context.

The problem here is that if the schema has been modified on the source
domain, there may be attributes that appear over DRS with 0 values (to
indicate that any existing values on the target should be deleted).
This would confuse the previous version of this macro.
Andrew Bartlett
O(n) search for dsdb_attribute by msDS-IntId value was
replaced by binary-search in ordered index.
I've choosen the approach of separate index on msDS-IntId values
as I think it is more clear what we are searching for.
And it should little bit faster as we can clearly determine
in which index to perform the search based on ATTID value -
ATTIDs based on prefixMap and ATTIDs based on msDS-IntId
are in separate ranges.
Other way to implement this index was to merge msDS-IntId values
in attributeID_id index.
This led me to a shorted but not so obvious implementation.
This allows the prefixMap from a DRS server to be used when loading
the schema from the local files. This helps us then import other
schema with this map in place.

The change here is to try and convert a per the previous rules, but if
we don't know a particular OID as a attributeID, then store it as an
OID (for example). This allows known values to be converted as
before, but still copes with unknown values.

This works on the assumption that the schema partition can only
contain schema objects.
We may need to pass down some kind of 'relax' to the DRS -> LDB
conversion code, so that it allows incomplete conversions, so that we
don't fail if a new attribute is present, and we can't decode it.
This would then be resolved the second time we do the conversion.

Error checking is simplified and my leave leeks.
I did it this way to make code more readable, and if we
get error in those lines, it will be WERR_NOMEM in which
case we are in a much deeper troubles than delayed freeing
of few bytes.
This reverts commit 8149094edd.
Windows implementation does not set schemaInfo attribute value
until first Schema update request.
This way, newly provisioned forest returns no schemaInfo value.
I think it won't be bad for us to have this value preset, but
I want to mimic Win AD behavior as close as possible.
The use of 'replace' is enough to wipe out the old value, whatever it
is, we don't need to set 'permissive modify' too.
Additionally, this seems to be causing trouble for the OpenLDAP backend
Andrew Bartlett
ldb_msg preparation is moved into separate function
so that it can be used for implementing schemaInfo
updates both on module stack (dsdb_module_... functions)
and directly on ldb_context
This commit reworks Samba4's schema loading code to detect when it
needs to reload the schema. This is done by watching the @REPLCHANGED
special DN.
The reload happens by means of a callback, which is only set when the
schema is loaded from the ldb - not when loaded from an LDIF file or
DRS.
We also rework the global schema handling - instead of storing the
pointer to the global schema in each ldb, we store a flag indicating
that the global schema should be returned at run time. This makes it
much easier to switch to a new global schema.
Andrew Bartlett
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
When specified, we talloc_reference onto this context to ensure that
pointers found in it are valid for the life of the objects they are
placed into. (Such as the string form of LDAP attributes).
Andrew Bartlett
Counters which are used in the way "for (i = 0; array[i] != NULL; i++)" I
modified to "unsigned" since for sure we don't want to have negative array
indexes there.
Counters which are used in the way "for (i = 0; array[i] != NULL; i++)" I
modified to "unsigned" since for sure we don't want to have negative array
indexes there.
There were many counter variables typed "uint32_t". This isn't fully correct
since those count LDB objects. The amount is saved in a "num_*" variable which
is "unsigned" without a bitlength specification. Therefore change also these
counters to be plain "unsigned".
ldb_dn_extended_filter() removes all but the listed components,
I didn't noticed that when writting the code.
Doing a ldb_dn_remove_extended_components(dn2) is wrong.
This was hidden by some bugs in the ldb_dn code.

This is a very heavy weight way of checking this syntax,
but it's very complex and using the existing function
should be ok for now. We can optimize it later.

When we get one we haven't seen before, we can work out the right type
automatically in most cases.
