Both ;-), the record should be added when you join a Samba DC, but if it 
isn't, then samba_dnsupdate should add it the first time Samba is run on 
a DC.

Ahh, a Windows DC will not have samba_dnsupdate, you will probably have 
to create the records manually with samba-tool or ADUC

You are using the Fedora packages to provision a DC, it looks like you 
might just have found another reason not use them for a DC ;-)

Couple of answers to that ;-)
