I have a domain, example.com
We own the example.com domain on the internet, and have a server hosted on Amazon using EBS - this gives us a URL which we need to point our domain to. In this case, we have setup server.example.com to point to EBS on the internet, with a cname - works without problems.
On univention, I've tried to setup server.example.com as a CNAME, however it simply doesn't work. The details save, but nslookup's fail.
Our local domain and forward lookup zone is example.com
Right now, I can't get server.example.com working locally due to this, I'm forced to use A records which eliminates Amazon load balacning.
