Indeed, it is....
You can only have one Kerberos realm named DOMAIN.
How do they know about each other?
There are DNS SRV records for Kerberos KDC and realm names.
Original Kerberos documentation mentions DNS is in:
Kerberos principles (not only DNS) are described in:
For example, if you have the windows domain/Kerb realm MYCOMPANY.COM,
you will not be able to have it coexist with an IPA server controlling
the realm MYCOMPANY.COM.
That's quite unfortunate. How can I work around this? Can I create
the realm BLAH.MYCOMPANY.COM or maybe even NOTMYCOMPANY.COM without a
DNS domain to match, or will I need to interface with the DNS admins?
Is there a good document that describes the nature of these realms and
their relation to DNS?
Best way is to create subdomain UNIX.MYCOMPANY.COM and fill it with proper SRV
records (or let IPA to manage it).
You can configure each all servers and client statically with /etc/krb5.conf,
but it is error-prone and not scalable.
Configuration with AD and IPA with same domain name is not supported, because
it confuses Kerberos libraries.
If it's an oldschool NT type domain you should be OK, but if it's
Active Directory (which uses Kerberos) you can't do it.
It's an Active Directory domain.
