[Samba] Migrate from Windows AD to Samba 4

[chidokato]

> Here is my implementation:
> Samba 4 with bind <----------------replicate-------------------- old
> windows AD
>
> After replication, I want to demote Windows AD (WAD) and turn it off. So
> I'll use Samba 4 as only active directory domain controller.
> Everything is fine until I join new client to my domain (samba 4 is now
> only AD, already update DNS). It pop-up an error: "Samba security database
> is corrupted", and here is my samba.log:
>
> ../source4/dsdb/repl/drepl_ridalloc.c:207: Failed to find fSMORoleOwner in
> RID Manager object - Cannot find attribute fSMORoleOwner of CN=RID
> Manager$,CN=System,DC=tuan,DC=local to calculate reference dn
>
> So, it's too much for me to handle this kind of error. Any idea?

> Thanks you all.
