Interesting question. I do not think bind-dyndb-ldap supports the $GENERATE
directive. I am not even sure how to extend LDAP DNS tree to support it as it
has a very specific syntax. You would need to add a new LDAP space accepting
strings that would be then passed to BIND... I will let Petr to assess if this
is possible or not.

For now, the best approach would be to either add all these records to LDAP or
to have it in a BIND zone file and synchronize between all FreeIPA DNS servers.
