The answer is:

IPA is even more strict, one DNS *name* can have only one TTL for all RRsets.

This limitation is enforced by LDAP structure we use. All DNS records for
single DNS name are stored in one LDAP object and DNS TTL is represented as
one attribute.

The follow up question is:

But dnsrecord_add/mod has a dnsttl attribute.  What happens if I do a
dnsrecord_mod {"dnsttl": adifferentvalue}?  Does it change the ttl for _all_

Yes it does, it should always affect the whole DNS name.

IMHO the right behavior for "import scripts" is to compute min(TTL in IPA, TTL of the new record) and use this value when adding a record.

Default TTL is now 86400 seconds. There is a plan to implement per-zone default TTL.

Let me know if you have some problems because of this, we can try to find some solution.
