As a part of CVE-2020-25717 mitigations, Samba now assumes 'CLASSIC
PRIMARY DOMAIN CONTROLLER' server role does not support Kerberos
operations. This is the role that IPA domain controller was using for
its hybrid NT4/AD-like operation.
Instead, 'IPA PRIMARY DOMAIN CONTROLLER' server role was introduced in
Samba. Switch to this role for new installations and during the upgrade
of servers running ADTRUST role.
