This is fine. If the alternate domain contain the "_kerberos.domain.com" DNS
TXT record with the ream, Kerberos client should be able to find the right IPA
server/KDC to talk to (if they have DNS discovery enabled). Recent FreeIPA
versions add this record to owned DNS zones automatically.

If autodiscovery with hosts in your alternate domain does not work, you can
also use just

# ipa-client-install --domain main.ipa.domain.com

and it should find the IPA server.

What I see above looks normal to me. [domain_realm] manual mapping can be used
if you have DNS autodiscovery disabled or you miss the DNS TXT record for
Kerberos, IIRC.
