RODC Samba DNS Records Not Replicating

UCS - Univention Corporate Server

Hello, how are you?

We installed a new RODC server with Samba DNS backend (ucsrodc).

dns/backend: samba4

As mentioned in the documentation:
Univention Documentation

When joining the server to the domain, the initial synchronization is performed and the existing records appear in Samba.

However, when we create new DNS records on the master, they are not replicated to the RODC DNS. (They do appear in LDAP, but not in Samba.)

Running the following queries on the RODC (ucsrodc) gives us:

samba-tool dns query ucsrodc.mydomain.com mydomain.com dnstest A -U Administrator
Password for [MYDOMAIN\Administrator]:
ERROR: Record or zone does not exist.

univention-ldapsearch -LLL “(zoneName=mydomain.com)” dn | grep dnstest
dn: relativeDomainName=dnstest,zoneName=mydomain.com,cn=dns,dc=mydomain,dc=com

Is this the expected behavior, or should the record also appear in Samba?

thanks very much,
best regards.

Hi @carlitostevez,

maybe this knowledge base articles could help you, to understand if the drs replication works in you environment and solve the issue.
