Fixed In Version:	ovirt-engine-extension-aaa-ldap-1.4.5	Doc Type:	Release Note
Doc Text:	ovirt-engine-extension-aaa-ldap has been using single request to fetch both A and AAAA records from DNS servers in mixed IPv4/IPv6 setups. Underlying JVM transformed this request to ANY DNS call, which has been recently deprecated by RFC 8482 and that why we haven't got valid addresses from some DNS servers. From version 1.4.5 ovirt-engine-extension-aaa-ldap is going to fetch A and AAAA records in separate DNS requests.	Story Points:	---
