To be absolutely sure I tried to put two CNAME records to one node. BIND 9.10 refuses to load the zone and gives following error: zone t1.test/IN: loading from master file t1.db failed: multiple RRs of singleton type zone t1.test/IN: not loaded due to errors.

Thanks, Gady Hello, you don't, ldapschema limits CNAME to just one value in IPA It is possible with BIND9.1+ to have multiple CNAMEs ? http://docstore.mik.ua/orelly/networking_2ndEd/dns/ch10_07.htm Anyway this is violation of RFC. You should use for load balancing A records.

[Freeipa-users] RoundRobin - Cname - 2 servers with same services
Hello World, I am trying to enable roundrobin on freeipa. I have 2 servers providing same service (http). I am trying to give it a friendly name so that when user what to access it, they can land on any one of the 2 servers. But IPA dns doesn't want to let me create CName that has the same name but 2 different destination. How do I go around this?
