Current implementation of ldb_msg_find_attr_as_* iterate on the list of
attributes returned by the search and make a string comparison. As we
sorting the array of messages / guids we tend to call this function many
times. By storing the GUID and the USN in a separate structure we are
sure to call this function only once per attribute and object.

when a DC has the GUID_DRS_GET_FILTERED_ATTRIBUTES right on a NC, we
need to allow it to replicate if all the attributes it is asking for
are in the GC partial attribute set

When an object is deleted, link pointed to it are marked as inactive.
When the same object is purged we do not remmove the link pointed to it
(we can't know them) so they stay in the database, it turns to be a
problem for Windows 2008.

this improved the logging of bugs related to linked attribute
replication

we now keep just a list of GUIDs around between getncchanges calls,
instead of an entire db search. This makes the overhead of having a
pending getncchanges call much smaller.

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

The merged I plan in this area require spliting security.h into
two header files, a common header and a session.h for the
remaining source4-specific code.

This implements partial attribute set checking on getncchanges. If the
client sends a partial_attribute_set then we only return the specified
attributes.
This also implements access checking on the NC root for the access
right GUIDs for requests with and without reveal secrets

in case we are handling extended operation.
It seems that windows accept both DRSUAPI_EXOP_ERR_SUCCESS
and DRSUAPI_EXOP_ERR_NONE, but Samba is a little bit
more picky on this.
Most of extended operations I know of work like:
1. do extended operation
2. collect a set of objects to return and start replication cycle
3. continue returning object as we have no more to give
This way we ensure we are doing 1. only once
This adds support for DRSUAPI_EXOP_FSMO_REQ_ROLE, DRSUAPI_EXOP_FSMO_RID_REQ_ROLE
and DRSUAPI_EXOP_FSMO_REQ_PDC.
Developed in collaboration with Anatoliy Atanasov <anatoliy.atanasov@postpath.com>
When DRSUAPI_EXOP_FSMO_RID_ALLOC extended op is handled
in DsGetNCChanges() stub, we need to returned a well know set of
object - see: [ms-adts], 3.1.1.5.1.7
With this hack we are going to return just objects modified
during RID allocation procedure - i.e. "RID Manager$", "RID Set" for
computer object and computer object itself.
Which is a close approximation of what we are expected to return.
This makes the structure much more like NT_USER_TOKEN in the source3/
code. (The remaining changes are that privilages still need to be merged)

when we deny a EXOP_REPL_SECRET call we should set the exop error code
to NONE, and the main return code to WERR_DS_DRA_ACCESS_DENIED (based
on observing windows server behaviour)

The rules for when a RODC can replicate secrets are:
- it can always replicate its own acct
- it can also replicate its krbtgt acct
- it can't replicate other krbtgt accts
- it can't replicate interdomain trust accounts
- it can't replicate users in the denied group list
- it can replicate users in the allowed group list
otherwise it can't replicate

When a RODC uses extended getncchanges operation
DRSUAPI_EXOP_REPL_SECRET it gets an override on the ability to
replicate the secret attributes.

Depending on which NC is being replicated, GetNCChanges() returns
either ATTID based on local prefixMap or msDs-IntId value of
the attributeSchema class for the attribute being replicated.
If set, msDs-IntId value is always returned when replicating
object form NC other than Schema NC.
Objects in Schema NC replica always use prefixMap based ATTIDs.
