IPA Service Discovery without DNS?

Is it possible to configure IPA for Service Discovery Without DNS and use it with RHEV-M?  When I run the rhevm-manage-domains command, the following error message is displayed:

Error: Authentication Failed. Please verify the fully qualified domain name that is used for authentication is correct.. Problematic domain is: example.com
Failure while applying Kerberos configuration. Details: Authentication Failed. Please verify the fully qualified domain name that is used for authentication is correct.
 

The following error entry is recorded in rhevm-manage-domains.log:

2011-12-20 10:36:55,679 ERROR [org.ovirt.engine.core.dns.DnsSRVLocator] Error in getting SRV list for protocol _tcp and domain EXAMPLE.COM Exception message is DNS name not found [response code 3]
