samba - Dec 2024 - FSMO transfer of PDC role creates new SRV record in DNS but does not remove old one

Hi,

AFAIK there should be a single DNS SRV record for PDC role in the domain, e.g.:

_ldap._tcp.pdc._msdcs.adx.mobiltel.bg. 900 IN SRV 0 100 389 dc01.example.com.

When doing a 'samba-tool fsmo transfer --role=pdc' on dc02, the reole is
being transferred and a new DNS record added, but the old one for dc01 is not
removed. Is there anything not working correctly in my setup or does it need to
be removed manually?

Also the dns_update_list does on have a line for adding the new record:
${IF_PDC}SRV           _ldap._tcp.pdc._msdcs.${DNSDOMAIN}                   
${HOSTNAME} 389

br

At the end. "One PdcEmulationMasterRole owner, one dns record"

This is a very old bug, see here:

Just delete the wrong dns record
