I will add few more details:

"ALIAS" virtual record and its derivatives are not standardized yet and AFAIK there is no implementation which works with DNSSEC.

IPA uses BIND 9.9 as DNS backend and BINDitself doesn't support any variant of ALIAS record at the moment. As a result, IPA doesn't have any means to provide this feature.

If you are interested in details please see dnsop mailing list archives [1] and look for "ALIAS" keyword in subjects.

Thanks Michael, it seems you are correct.

I knew I’d seen it done though - turns out that if you use route53 for your DNS 
amazon has a way of making it work with a virtual record type called an alias. 
I guess we’ll just have to use route53. At least alias lookups are free.

Hello everyone : )

Is it possible to configure a CNAME for a bare domain with freeIPA?

We would like to move our site over to an Amazon ELB, but to do so we have to 
point our domain (foo.com, not www.foo.com) at an was A record with a CNAME 
(something like xxxxxxxxxxxx.eu-west-1.elb.amazonaws.com)

This is technically possible, but IPA complains:

"invalid 'cnamerecord': CNAME record is not allowed to coexist with any other 
records except PTR"

I’m guessing this is because of the @ NS record.

Is there any way to override this behaviour? Can I make manual modifications to 
the zone file?
