David-

We have multiple domains that we want to manage under one Kerberos realm. I
see that's it's possible for FreeIPA to manage multiple realms, but, for
simplicity, I'd rather use just one and have all domains underneath:

REALM.COM
controls example1.com, example2.com, example3.com, etc.

Since we control all domain's DNS, we would create text records for each of
the example{x}.com domains pointing to REALM.COM Kerberos realm. We would
also create SRV records for each of the example{x}.com domains directing
Kerberos lookups to REALM.COM. I know it's a little unorthodox, but I'd
like to do it so we can keep everything in one easily managed lot.

P.S. I got several pornny spammy replies to this message. Is someone
sneaking into this list somehow?
