I downloaded and built Samba 4, and I'm at the step where I'm trying to add it to the domain and I'm getting a replication error when it's trying to do it's initial replication. bin/samba-tool domain join domain.coop DC -Uusername --realm=domain.coop Finding a writeable DC for domain 'domain.coop' Found DC DC.domain.coop Password for [DOMAIN\username]: workgroup is DOMAIN realm is domain.coop checking sAMAccountName Adding CN=SambaServer,OU=Domain Controllers,DC=domain,DC=coop Adding CN=SambaServer,CN=Servers,CN=SV,CN=Sites,CN=Configuration,DC=domain,DC=coop Adding CN=NTDS Settings,CN=SambaServer,CN=Servers,CN=SV,CN=Sites,CN=Configuration,DC=domain,DCcoop Adding SPNs to CN=SambaServer,OU=Domain Controllers,DC=domain,DC=coop Setting account password for SambaServer$ Enabling account Calling bare provision No IPv6 address will be assigned Provision OK for domain DN DC=domain,DC=coop Starting replication Schema-DN[CN=Schema,CN=Configuration,DC=domain,DC=coop] objects[402] linked_values[0] Schema-DN[CN=Schema,CN=Configuration,DC=domain,DC=coop] objects[804] linked_values[0] Schema-DN[CN=Schema,CN=Configuration,DC=domain,DC=coop] objects[1206] linked_values[0] Schema-DN[CN=Schema,CN=Configuration,DC=domain,DC=coop] objects[1376] linked_values[0] Analyze and apply schema objects Partition[CN=Configuration,DC=domain,DC=coop] objects[402] linked_values[0] Partition[CN=Configuration,DC=domain,DC=coop] objects[804] linked_values[0] Partition[CN=Configuration,DC=domain,DC=coop] objects[1206] linked_values[0] Partition[CN=Configuration,DC=domain,DC=coop] objects[1608] linked_values[55] Partition[CN=Configuration,DC=domain,DC=coop] objects[1650] linked_values[10] Replicating critical objects from the base DN of the domain Partition[DC=domain,DC=coop] objects[96] linked_values[20] Partition[DC=domain,DC=coop] objects[434] linked_values[64] Partition[DC=domain,DC=coop] objects[698] linked_values[37] Partition[DC=domain,DC=coop] objects[945] linked_values[20] Partition[DC=domain,DC=coop] objects[1130] linked_values[45] Refusing to replicate DC=TAPI3Directory\0ADEL:421d2b48-4a80-45e1-a921- b1700eb4daca,DC=domain,DC=coop from a read-only repilca into a read-write replica!

I deleted it and it didn't seem to help. I've also run ldp.exe, and tried to find it that way. As well as running repadmin /removelingeringobjects thinking it might just not have been fully deleted. Is this just having to wait for the tombstone lifetime of the deleted object to pass, or is there something I can do to fix this and get the replication working for the Samba 4 server I'm trying to setup.
