All DCs are Raspberry PI's. The setup was running fine, after i tried to upgrade to 4.8.0. I reverted to 4.7.5 and have now this error: UpdateRefs failed with WERR_DS_DRA_ACCESS_DENIED/NT code 0xc0002105 for 63f4e656-6590-4c1d-a362-c3b97b5e464d._msdcs.local.laurenz.ws CN=Schema,CN=Configuration,DC=local,DC=laurenz,DC=ws No Matter which DNS Backend - i prefer bind by the way.. What happend in Detail: Compiled 4.8.0 and created a deb package Installed this deb package on DC3 (Hostname samba03) Starting Samba 4.8.0 on that DC and all tools (samba-tool) for example fail with complaining about to less memory Deinstalled samba 4.8.0 and installed 4.7.5 Run source4/scripting/bin/sambaundoguididx on DC3 Start Samba 4.7.5 After that the above error occurs.. Then demote and rejoin Then demote and remove dead dc running on DC1 then join Then demote and delete all db-files and rejoin Then demote and delete all db-files and rejoin - with dns_backend=BIND_DLZ Then demote and delete all db-files and remove dead dc running on DC1 and rejoin - with dns_backend=BIND_DLZ Setting replication Issues via Active Directory Sites and Trusts. DC1,2 are in Site A, DC3 in Site B The mentioned failure still exists. I have no idea any more.
