First writings on DsGetNCChanges call

[Anatoliy Atanasov]

Hi Team,

Last couple of weeks I am trying to start writing the dcesrv_drsuapi_DsGetNCChanges call.

So far I tried to return meaningful ctr6 structure in response to RPC-DSSYNC test.

I uploaded the work-in-progress branch here: http://repo.or.cz/w/Samba/aatanasov.git?a=shortlog;h=refs/heads/samba_drsuapi
Sorry for the delay, got really busy here and couldn't do much sooner.

There is a problem I found with DSSYNC test against windows 2003 and I tracked it down and fixed it in commit 35bf701c3195f18e10d15f018be2fb828e891bc1: "Fix for DSSYNC test against Windows 2003"

The other case that I hit is in the implementation of dcesrv_drsuapi_DsGetNCChanges. I use dsdb_attribute_ldb_to_drsuapi() to format the reply for the object's attributes but the function is not complete I think because I got a segfault in strange location. 
I suspect schema_syntax.c:735 there is call to dsdb_syntax_FOOBAR_ldb_to_drsuapi and I can't get the objectGUID in the response correctly.  

Metze, I guess its time to start digging into the linked attributes issue.
Tridge, I am very interested in what part of the Replication you are working on.
Andrew, I will keep tracking on tasks on the Fantasy page, at last I can update it with some actual work. 

Looking forward to here from you guys soon,
Anatoliy
