Did you have an existing dns server for your domain ?

If your read our documentation, you would find that we do not recommend 
using your dns domain, it is recommended to use a subdomain.

Probably the best idea, but you would need to provision again, because 
you will also have to change the dns domain (because the REALM is the 
dns domain in uppercase).

Not that I am aware of.
