The actual hostname is the output of hostname -s
The primary dns domain is the output of hostname -d 
The hostname you should use, is the output of hostname -f 
Your kerberos domain is != hostname -d 

hostname -A and hostname -I  shows all ipadress and hostname/aliasses. 

The resolving order matters a lot in resolv.conf 

And your krb5.conf has problely something like this. 
    default_realm = AD.INTERNALONE.COM

Thats where the kerberos domain is ( the added part ) is comming from. 

But! I dont know lot about RH/Centos, so correct me here if im wrong here.
