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.
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
The getncchanges call needs to be able to access the sam as the system
user for RODC clients. To do this it needs a sam_ctx connection with
system credentials

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.
w2k8r2 is setting this bit as a RODC. Instead of refusing the
replication, we now remove the bit from req8, which means other places
in the code that check this bit can stay the same

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

Windows gives them in chunks, but I don't know the correct
rule to calculate the chunk size.
For now I'll use 1500 as the max size.
Windows isn't happy when it gets ~ 100000 linked attributes in one
response. It corrupts its directory index and later moves some objects
to the LostAndFound folder.

This checks whether a replication client is a RODC by inclusion of the

This is used for allowing operations by RODCs, and denying them
operations that should only be allowed for a full DC
This required a new domain_sid argument to

During building an object to send it on a GetNCChanges reply, it checks
the attributes and if any of them is a RODC filtered and the recipient
is a RODC, then such attribute is not sent.

This patch creates the samdb_is_rodc() function, which looks for
the NTDSDSA object for a DC that has a specific invocationId
and if msDS-isRODC is present on such object and it is TRUE, then
consider the DC as a RODC.
The new samdb_rodc() function uses the samdb_is_rodc() function
for the local server.

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.

The replPropertyMetaData may contain attrid values that we don't yet
have in the local schema. We need to deal with this - it is a serious
error, but we should not segfault.
